The union of farming and metalworking has led to many of civilizations technological and agricultural developments. Before the invention of farming, most early civilizations existed as gatherers and hunters. Because farming created the conditions in which people could settle, it ultimately contributed to the building of modern society and culture. Farming, and the stability farming provided humanity, led to the benefits of modernity: technology, politics, literature, the arts, and culture. Metal, like farming, helped to tilt the balance of power between mankind and nature towards mankind. Human beings could finally subdue the natural elements around them, which, beforehand, they seemingly had little to no control over.
Before the union of farm work and metal, farmers had inefficient tools to contend with the harsh conditions. These medieval farms only produced somewhere between 4.34 seeds for each seed of wheat sown. Entire village populations were constantly on the brink of starvation. Metalworkers introduced the iron plow to farmers, who had been using the ineffectual wooden plow. The new iron plows could cut through the heavy northern European soil, even during winter frost. This mingling of metal and farm work, among other technological/intellectual developments, led to the Enlightenment era and a population boom that reshaped the social order.
Today, the interaction between farming and metalworking continues to provide humanity with bountiful harvest. Although farms have become much more efficient, profit and competitive margins remain slim. Advances in metallurgy – like galvanized steel, are a keystone to modern farming operations by helping farmers to save time and money.
The Benefits of Galvanized Steel
Galvanized metal has been around for hundreds of years, although the methods for applying the zinc coating have become more sophisticated.
Less expensive when compared with most treated steels.
Lower in maintenance cost than other coated metals – saving time on repairs and replacements.
Damage-resistant, very durable, and can withstand outdoor elements.
Self-healing in the way it’s coating provides automatic protection for damaged areas and will corrode preferentially to the steel, creating protection to the areas that are damaged.
Ready to use immediately upon delivery – it does not require additional preparation of the surface (painting/coatings, etc.) prior to installation.
Agricultural Galvanized Steel Advances
The longevity of galvanized steel is economical. It’s low maintenance enables farmers to spend their time running the farm. Galvanized steel can be found in virtually every area of a modern agricultural operation. Modern farmers—wise to the cost in savings by using this affordable, maintenance-free, rust-protected steel—use galvanized steel on fences, storage facilities, equipment, external structures, and for many other applications.
Today farmers are taking advantage of galvanized steel and galvanized high strength steel for agriculture in the following applications:
Grain elevators and conveyors
Milk storage containers
Silo Extraction Equipment
High Speed Freezing Equipment

Expansion & The Future of NMM
In 2017, National Material Company announced the expansion of their plants in Mexico for a twofold reason: first, to meet increased demand and second, to focus on the futuristic Advanced High Strength Steel that is going into cars. As VP General Manager Carl Grobien explains:
“We opened up this facility in 1997 with one slitter. Now, we have two slitters, one for electrical steel and one for carbon steel. After so many years, the first slitter is more than 100% full and with the new generation steel, AHSS or Advanced High Strength Steel, going in to automobiles, our steel now goes into lighter cars with better gas mileage. So AHSS are extremely strong, very hard: the equipment we are putting in is focused on the future of those types of requirements from the industry.”
Expanded steel processing area to accommodate AHSS slitter and new plant equipment

No one has ever walked into a car dealership and said to the salesperson: “Hey, do you have anything made out of an unstable material?” When assembling vehicles, car manufacturers face a specific challenge: they need materials with seemingly contradictory properties: lightweight, but strong, and highly formable into rigid structures. This is a challenge in light of how metals deform. The strains from forming accumulate into localized areas on the part, leading to excessive thinning known as “necking.” These areas are thinner than the rest of the part, and are the most likely to have durability or fatigue problems during the vehicle life. Higher strength materials are more likely to experience “necking” during the production process, which, in turn, creates an unstable part. Most would agree that would never be a good quality in a car.
The first antidote to this challenge was introduced in the 1980’s when the steel industry developed interstitial free (IF) steels. These steels have a microstructure primarily consisting of a single phase known as ferrite, which is iron with typically less than 50ppm carbon in an interstitial solid solution. It has a body-centered cubic (bcc) structure at room temperature. ULC steels are highly formable, a desirable trait for auto companies that have a high demand for steel that can be molded into the new complex shape of cars. However, these steels are relatively soft which makes them poor candidates for the automotive body structures that need to withstand increasingly stringent crash resistance requirements. Steelmakers had to create new steel grades that combine mechanical strength with high ductility (the ability to undergo significant plastic deformation before rupture). Enter advanced high strength steel!
What is AHSS?
The metallurgy and processing of advanced high strength steel (AHSS) grades are somewhat novel compared to conventional steels. Their remarkable mechanical properties are the result of their unique processing and structure. They are classified into categories based on their microstructure or how they deform: dual phase (DP) steel, transformation-induced plasticity (TRIP) steel, complex phase (CP) steel, martensitic (MS) steel, ferritic bainitic (FB) steel, and twinning-induced plasticity (TWIP) steel. AHSS solves two distinct automotive needs by using two different groups of steels. The DP and TRIP grades of steel have increased values of the work hardening exponent. These possess higher strength levels with improved formability and crash-energy absorption compared to the current HSLA (High Strength, Low Alloy) grades. The CP and MS grades extend the availability of steel in strength ranges above the HSLA grades.
Additional steels are designed to meet specific process requirements. These include increased edge stretch flangeability, strengthening after forming, and improved bendability. By combining a number of different microstructures not traditionally found in conventional high strength steels and controlling the phase distribution, a wide range of properties are possible. This allows steel companies to tailor their processing to meet the ever-more focused application requirements demanded by the automotive industry.
Why is AHSS so beneficial for auto manufacturers?
AHSS is most advantageous when used for safety components of automobiles and their structural parts where high strength with reasonable ductility is important. AHSS has become the material of choice for passenger safety cage components like sill reinforcements, A-pillars, B-pillars, side impact beams, waistline reinforcements, bumpers, and roof bows. Advanced high strength steel has also been introduced in all other vital areas of the automotive industry, like seats. Many new cars are already composed of 30% – 40% AHSS. The high strength of AHSS is a useful tool to reduce the weight of bumper systems, door side impact beams, seat structures, etc. The advantages of using AHSS are evident in all types of automobiles. Small cars benefit from greatly improved crash safety while heavier cars, like SUVs, can be made much more fuel efficient. There has been a smooth and cost-efficient transition from mild steels, or conventional high strength steels. The qualities of AHSS make it a leading success factor behind improvements the automotive industry.
AHSS in 2020: towards a clean future
Advanced high strength steel is beneficial for several reasons including:
A decreased carbon-footprint. AHSS is strong, light, and produced with a reduced life cycle impact – helping automakers decrease a vehicle’s life-long carbon footprint.
Fewer e The use of AHSS contributes to a 5% reduction in greenhouse gas emissions. New grades of advanced high strength steels enable carmakers to reduce vehicle weight by 25-39% compared to conventional steel. When applied to a typical five-passenger family car, the overall weight of the vehicle is reduced by 170 to 270 kg, which corresponds to a lifetime saving of 3 to 4.5 tons of greenhouse gases over the vehicle’s total life cycle.
Electric v Like most automotive manufacturers, the producers of electrical vehicles favor AHSS over aluminum because it’s strong and cost effective. Electric vehicles are gaining widespread popularity due to their high-performing nature, efficiency, and aesthetic appeal. AHSS is leading the way towards a clean and green future.
NMC’s commitment to AHSS and the future
