History of Galvanized Steel in the Automotive Industry

2019-04-12T01:54:39+00:00 March 21st, 2019|News Blog, NMC Media|

Galvanized steel is among the most popular and useful steels due to its durability, cost effectiveness and, most importantly, its rust-resistant qualities. But galvanized steel wasn’t always in high demand.

In the early 1990’s, steel was consistently the go-to material in automobile manufacturing, but public demand for corrosion-resistant steels in the North American market hadn’t become wide enough for manufacturers to begin implementing it.

In fact, it wasn’t until the late 1980’s, when the Japanese began importing automobiles with anti-corrosion features, that Western markets would discover the advantage of the material. Galvanized steel was indispensable in Japan, a country with a coastal environment that created heavier levels of oxidation and rust.

At the time, North American made vehicles were experiencing severe durability issues due to rust – a serious issue that (quite literally) couldn’t be solved by just throwing on another coat of paint.

Western automakers had developed specific standards for their warranties which further exacerbated the problem of switching to galvanized steels, as its implementation into processing lines would take serious time and money. However, forced to compete, they began to make the transition.

This important switch led to the use of electrogalvanizing lines.

Electrogalvanizing is a process in which a layer of zinc is bonded to steel in order to protect against corrosion. The process involves electroplating, running a current of electricity through a saline/zinc solution with a zinc anode and steel conductor. The plating of zinc was developed at the beginning of the 20th century. At that time, the electrolyte was cyanide based. A significant innovation occurred in the 1960s, with the introduction of the first acid chloride based electrolyte…The 1980s saw a return to alkaline electrolytes, only this time, without the use of cyanide.” (Source: Wikipedia)

Going into the mid 90’s, electrogalvanizing was the only process that was approved for automotive quality; but automakers had set their sights on another way to galvanize steel – hot dip galvanization. This technique was being used in other markets, but hadn’t yet reached the level of quality necessary for automobiles. That is, until the 1990’s.

Nowadays, the use of zinc-coated bodies for automobiles is standard procedure in auto manufacturing. The ‘body-in-white’ of a car makes up about 80% of the body, all using galvanized steel. The rust resistance of galvanized steel is also a good marketing tool for the automotive industry because they can provide anti-rust warranties to customers.

What are the Benefits of Galvanized Steel?

There’s a reason so many different industries utilize galvanized steel. It has a wide array of benefits for industries to take advantage of, including:

  • Low initial cost compared to most treated steels.
  • Lower maintenance costs than most coated steels (saves time on repairs and replacements).
  • Increases durability of the steel’s finished product which also increases the product’s reliability.
  • Galvanized steel is very protective, including sharp corners and recesses that couldn’t be protected with other coatings, making it resistant to damage.
  • Self-healing, meaning the galvanized coating includes an automatic protection for damaged areas. The coating will corrode preferentially to the steel, creating a sacrificial protection to the areas that are damaged.
  • Galvanized steel is immediately ready to use when delivered. It does not require additional preparation of the surface, inspections, painting/coatings, etc.

Advanced High-Strength Steel Rules the Road in 2019

2019-02-05T17:59:41+00:00 February 5th, 2019|News Blog, NMC Media|

Advanced High-Strength Steel is a new generation of steel revolutionizing the automotive industry. The widespread use of advanced high-strength steel doesn’t seem to be slowing down as we move into 2019. This high-performance material offers high-strength and low weight, all while maintaining formability that is crucial to the automotive manufacturing process.

Strong and dependable, steel continues to be the frontrunner when it comes to car manufacturing. A recent survey showed that steel is the preferred material in automobiles, with 90% of consumers saying they believe steel is stronger than other materials used by automakers. 75% said that a car’s crash safety, and other safety features, were the most important factors when buying or leasing a vehicle.

Various automotive manufacturers have announced intentions to increase their use of AHSS in automobiles, and several 2019 and 2020 models made with higher proportions of the advanced high-strength steel have already been unveiled.

Last month, a large automotive manufacturer “…revealed its brand-new “flagship” three-row SUV, describing a steel body with a 13.7 percent higher average tensile strength than its next-generation 2019 coupe.”

The article continues to highlight the SUV’s new build, saying it has “…a very rigid structure, with strategic use of Advanced High Strength Steel (AHSS) in key suspension and crash areas to provide increased tensile-strength. Use of Advanced High Strength Steel has several benefits: lighter overall vehicle weight and greater vehicle strength and rigidity without the excessive costs of more exotic lightweight materials.”

The SUV “…is expected to achieve TSP+ from the IIHS and a 5-star NHTSA rating. Robust underbody and side structures are designed to increase energy absorption and cabin intrusion in a severe collision, especially in the small overlap test. Further, its underbody uses multiple load paths to better disperse potential crash energy in the event of a collision.’”

Another automotive manufacturer announced that “The 2019 sedan model ‘strengthens its bones’ for its third generation, describing a body made up of 54 percent advanced high-strength steel.”

The vehicle also added “hot-stamped components”, a reference likely to indicate ultra-high-strength steels.

This new configuration is likely to restrict what auto body shops can do to the popular sedan. Higher-strength steels tend to carry heat, sectioning and repair restrictions because of their metallurgy or role in crash protection.

“Because body stiffness plays a major role in NVH performance, engineers worked to increase rigidity for a quieter cabin and better handling tuned to match the car’s sporty and dynamic exterior appearance, resulting in a 16 percent stiffer body in white,” the automotive manufacturer wrote in a news release Wednesday.

“New subframe designs help to improve lateral responsiveness, while steering feel is upgraded compared to its predecessor’s thanks to enhancements within the Motor Driven Power Steering (MDPS) system that reduce artificial steering feel and friction.”

Throughout the last year, we shared information on the various types of AHSS products, including DP Steel, TRIP, Complex Phase, and more.  The widespread use of advanced high-strength steel doesn’t seem to be slowing down as we move into 2019.

The Life Cycle of an Ultra High-Strength Steel

2018-11-16T17:27:20+00:00 November 25th, 2018|Uncategorized|

Hot molten metal being poured into long, thin cast.

In recent years, the automotive industry has benefited greatly from the integration of advanced high-strength steels (AHSS).

Each step of the manufacturing process of a new advanced high-strength steel, the different configurations of chemical composition, and achievable microstructures, is a result of a closely controlled heating and cooling process. During these processes, several strengthening mechanisms are employed to achieve different levels of strength, fatigue tolerances, and toughness.

Among the advanced high-strength steel family are Dual Phase (DP), Complex Phase (CP), Transformation-Induced Plasticity (TRIP), Martensitic (MS), and Ferritic-Bainitic (FB). They are all produced by controlling the chemistry and cooling rate in the austenite-ferrite phase during the hot rolled phase or in the annealing furnace.

But, what are the steps that are taken to create each of these materials? What are all the factors that metallurgists are searching for when they undertake such a task?

Here’s a checklist:

Designed for mass production

The driving force behind creating any variant of AHSS is to produce it on a mass scale. Therefore, starting from day one, full-scale processing concerns are addressed in the design. Different compositions are simulated and tested to achieve the most optimal composition.


The materials’ forgeability refers to the total fatigue, fracturing toughness, and tensile strength tolerances of the steel alloy.


Tests are rendered on the material to observe its boring, tapping, milling, threading, drilling, and turning capabilities. Everything is tested, from the optimal insert and cutting tool configurations to the best feed speed.

Heat treatment

The material will be tested for the mechanical differences between their annealed and hardened states.

Combination of properties

There are an incredible amount of possible alloying compositions using elements such as cobalt, nickel, manganese, copper, carbon, chromium, and more. Rigorous testing is done on the different alloy compositions to achieve the optimal desired properties.

What’s the key factor in any structure material? Its functional strength. The ultimate tensile strength (UTS) is the most important aspect of weight-limiting designs, so this property is the among the most crucial in the creation of new AHSS steels.

Fracture toughness

Another important element of the steel is its fracture toughness. This measures the materials’ ability to resist fracturing under stress.

Yield strength

As opposed to fracture toughness, yield strength refers to the point at which the fibers of the material begin to break down, and its form becomes plastic, instead of elastic. A higher yield strength will allow part designs to endure more stress before becoming disfigured.


Once the material is created and tested for mass production, it begins its life as it is machined into a useable part for the automotive industry. What happens as it’s made, put out into the world, and comes to the end of its life cycle?

Efficient steel production

Though AHSS is, at the moment, more expensive overall to produce than traditional steel grades, it uses less overall materials within the manufacturing process. The aim of AHSS’s is to reduce their weight while simultaneously achieving higher strength. A byproduct of this design philosophy is that less material waste is used during its creation.

Production methods

After its initial production, the material is further worked with during a processing series of casting, hot rolling, cooling, pickling, cold rolling, then annealing.

Reusing materials during the process

Manufacturers will attempt to use residual materials, byproducts of the manufacturing process, and recirculate them into the steel production process as opposed to using raw materials. This makes the material more cost effective and renewable.

Resource-efficient product manufacture

The pursuit of lower carbon emissions and increased crash safety is the purpose of AHSS’ strong and light properties. Some modern cars are made of more than 50% AHSS.

Recyclability of steel

Steel is the world’s most recycled industrial material, and maintains its properties no matter how many times that it’s recycled, similar to aluminum. Products made from steel have a long useful life and can then still be recycled indefinitely.
