What is Steel Processing? The Processes That Shape and Support our World

andre2021-04-26T16:18:27+00:00April 26th, 2021|News Blog, NMC Media|

It is easy to take the miracle of mass-produced steel for granted. Just in 2019, 1869.9 million tons (Mt) of steel rolled out of facilities and into our appliances, cars, planes, buildings, roads, and beyond. Yet, the steel processing that we enjoy today has been a work in progress for centuries, a work that, today, is evolving towards greener, more eco-friendly production.

What steps go into the processes that shape and support our world?

Raw Materials:

As has been done in the past, much of today’s steel processing begins with mined raw materials: iron ore, coal, and limestone. The molten iron produced from these initial materials are transformed into steel using a basic oxygen furnace or a modern electric arc furnace

However, the steel industry’s commitment to green processes means that every year in the United States, 70 million tons of steel are recycled, producing astonishing energy and raw material savings by the American Steel industry. According to World Steel, “A basic oxygen furnace can be charged with as much as 30% steel scrap. An electric furnace can be charged with 100% steel scrap. On average, new steel products contain 37% recycled steel.”

Refining, Adjusting, and Casting:

After the production of molten steel, a flurry of different processes can be applied, the most basic of which is when elements are either added or taken away to manipulate the final characteristics of the steel. Currently there are over 3,000 steel grades, each with a different balance of elements and heating adjustments to produce the desired properties. This includes the advanced high-strength steel grades.

When finished undergoing secondary steel making processes, molten steel is cast into “semifinished” billet, bloom, or slabs preparing the steel for its final physical shape.

Forming, Fabricating, and Finishing:

Afterwards, steel processing service centers take steel billets, blooms, and slabs and create deliverable steel products. This includes forming steel through hot rolling and cold rolling, and applying processes such as:

Steel Blanking
Steel Pickling
Steel Slitting
Shearing
Leveling
Milling
Saw Cutting
Drilling
Flame Cutting
Tumbler
Burning

The steel service centers then deliver the steel to final manufacturers who will transform it into a final, consumer product such as automobiles and appliances.

Coming full circle:

As mentioned earlier, The EPA estimates that nearly 70% of U.S. steel is recycled, meaning that the life cycle and processing of steel never truly ends, but begins again to create a healthier environmental future.

Steel’s Versatility: Why the Steel Industry Stands the Test of Time

andre2021-02-08T20:20:57+00:00February 8th, 2021|News Blog|

Steel’s broad applicability has made it the world’s sweetheart. It’s a stalwart in everything from modern décor, to structural elements, to specialty parts in aerospace, automotive, shipbuilding, military, and infrastructure industries. Even landmarks such as the Golden Gate Bridge and the Gateway Arch shine bright with steel produced by the American steel service industry.

Futurists, such as Elon Musk, have called steel “the best decision they have ever made.” The ancient general Alexander called strong enemies “walls of steel.” All this praise speaks to steel’s remarkable characteristics. In this blog, we will focus our attention specifically on steel’s versatility.

Steel can be used in a broad swath of temperature ranges

Highs

High-temperature grades of stainless steel can be used in temperatures up to 2100° F. This allows them to be used in furnaces, ovens, boilers, valves, and pipes. This also makes them ideal in the aerospace industry.

Lows

In low temperatures, many steel grades tend to become brittle after a certain threshold. A case in point was the steel hull of the Titanic which suffered brittle fracture in the steel bolts. However, modern steel grades have vastly improved on their low temperature range with cryogenic steels that show 100 Joules of toughness at -196 degrees Celsius.

Steel: perfect for exposure to chemicals and the elements

Hygiene

Stainless steel’s resistance to corrosion allows it to withstand many chemical cleaners. This makes it an ideal surface for many industries that require high levels of hygiene, especially in such applications as kitchens and chemistry labs.

Longevity

The Chrysler building’s stainless-steel roof, a pinnacle of Art Deco architecture, has only been cleaned three times since its construction in 1930! This is a strong flex on steel’s longevity and anti-corrosion properties that can resist the most damaging natural elements.

The average life of a steel product? 40 years.

Innovation and Specialization

The secret to steel’s versatility is the process of constant improvement since its discovery more than 4,000 years ago. With so much research, it’s no wonder that steel is such a specialized metal with an intricate grading system to categorize every form of steel.

Specialization

Whatever the job, there is a steel grade for it. Different techniques cause variances in ductility, toughness, machinability, and ability to be welded.

According to the World Steel Association, there are more than 3,500 grades of steel, each with its own unique properties. This includes the grades known as advanced high strength steels.

Innovation

When Hittites were creating steel 3,000 years ago, they probably created it by accident when the carbon from their furnaces mixed with iron. Since then, metalworkers have not only perfected the creation of different steel […]

Steel Processing at National Galvanizing

andre2020-09-30T19:24:37+00:00September 30th, 2020|News Blog|

Today, modern chemists must face the same problem that one element posed to the Egyptians thatshould have destroyed the pyramids. It’s that ubiquitous element that threatens everything made by humans: water. As frost formed inside the stone structure at night and expanded with the morning, slow cumulative damage should have been done to the pyramids. For many years, this mystery defied the explanation of archeologists, however was eventually solved. A detailed study concluded that ancient Egyptians relied on technology to defy the power of water: they had invented a primitive form of cement.

Water threatens the integrity of modern structures. Steel, the very backbone of modern civilization, rusts when it comes into contact with water. Technology has been the answer for modern man, just as it was for the pyramid builders. Various techniques have been developed to prevent steel from corroding. One of the most sought after by leading industries is galvanizing. Both long-lasting and cost-friendly, galvanized steel can resist rust for 70 years or more. The characteristics of the environment where it is used, and the thickness of the protective coat can influence the lifespan of the steel. Today, a sophisticated process known as hot-dipping is used to galvanize steel. Essentially, galvanizing adds a zinc-iron coating to the metal, forming a protective layer. The multi-step process described below gives galvanized steel its protective qualities:
1) The steel is cleaned in a degreasing solution.
2) After being cleaned, the steel is pickled by running through various tanks containing hot sulfuric acid.
3) The steel is then fluxed in an aqueous solution (typically zinc-ammonium chloride).
4) After the flux, the steel is galvanized through immersion in a vat of molten zinc.
5) Afterward, the steel is inspected for consistency and a complete coating.
Galvanized steel has a low, initial cost, and no need for maintenance. It also provides other important advantages:
• Rust resistance: The iron elements in steel are incredibly prone to rusting, but the addition of zinc acts as a protective buffer between the steel and any moisture or oxygen.
• Easy inspection: It is easy to tell how strong a galvanized coating is just by looking at it. There are also quick stress tests that can determine how thick the zinc coating is.
• Sacrificial anode: This ensures that any damaged steel is protected by the surrounding zinc coating. It does not matter if the steel section is completely exposed; the zinc will still corrode first.
• Longer life: With galvanization, a piece of industrial steel is expected to last 70 years in average environments and can last over 20 years with severe water exposure. No maintenance required.
Galvanization is part of a larger framework in steel preparation. Clients can benefit through facilities that can apply various processes to steel including hot-dipped galvanizing. That’s why National Galvanizing’s state-of-the-art facility enables pickling, galvanizing, galvannealing, and slitting, all in one location. As a joint venture between National Material L.P. and Heidtman Steel, National Galvanizing has an unparalleled structure for quality, high-speed supply that serves the automotive, heavy truck, agricultural, garage door hardware, and HVAC industries, among others.

Steel and Recycling: Fun Facts!

andre2020-08-06T19:53:22+00:00August 6th, 2020|News Blog|

Here at National Material Company, we thought we’d pause, reflect, and share some good news and fun, interesting facts about the steel industry.

In 2016, Azo CleanTech reported that steel is the most recycled material in North America. The metal comes not only from cans but also from construction scraps, automobiles, and appliances, and it can be turned right back into steel that can be used in the same applications.

Recycling is at the core of the steel industry’s commitment to sustainability. According to steel.org, the North American steel-making furnaces “consume nearly 70 million tons of domestic steel scrap in the production of new steel.” By using steel scrap to make new steel, the North American steel industry conserves energy, emissions, raw materials, and natural resources. This commitment drives the reduction of steel’s environmental footprint, while producing advanced, highly-recycled steel products that meet an advancing society’s needs.

Here are some fun facts about steel and recycling:

Steel products can be recycled repeatedly without loss of strength.
Recycling steel saves the equivalent energy to power about 18 million households for a year.
More than 80 million tons of steel are recycled each year in North America.
For every ton of steel recycled, 2,500 pounds of iron ore, 1,400 pounds of coal, and 120 pounds of limestone are conserved.
Almost 69 percent of all steel is recycled in North America each year – more than paper, aluminum, plastic, & glass combined. North America’s average steel recycling rate has been in excess of 60 percent since 1970.
More than 95 percent of the water used for making steel in North America is recycled.
One scrapped car produces more than four steel utility poles.
95 percent of the steel taken from commercial construction demolition sites was recycled and made into new steel products in 2002.
100 percent of a steel roof can be recycled. Asphalt roofs – zero percent. (Steel roofs provide your family with excellent protection against wind, water, snow, ice, and fire and are even hail-resistant. Asphalt roofs actually weigh twice as much as steel roofs. Steel roofs can last over 50 years, while traditional roofs last only 17 years!
Steel food cans are the most recycled food package. 24,000 community recycling programs in North America collect steel cans. Canned food is as nutritious as its fresh and frozen counterparts upon preparation! Canned goods do not contain preservatives!!
All 99 pounds of steel in the average major appliance can be recycled to make
new steel products.

Also, according to Utah Recycles, there are many more encouraging examples of how the steel industry’s commitment to recycling is helping to save the planet. Steel only takes up to 100 years to fully decompose in a landfill, whereas it takes plastic 1000 years to break down (aluminum can take 200 years, tin can take decades)! Recycling steel takes 25% less energy and creates only 25% of the water and air pollution required to produce steel from raw materials. About 70% of all metal is […]
