A Deeper Dive into Steel & Steel Processing

Cara2022-08-05T16:28:02+00:00January 14th, 2022|News Blog|

In an ancient Greek myth, Prometheus steals fire from the gods so that humans may escape their wretched situation on Earth. A modern rendition of this myth may have Prometheus bringing us steel rather than fire.

It is steel, strong and versatile, which releases modern humans from the constraints of nature. It is a stalwart in everything from medical equipment to structural elements, to specialty parts in aerospace, automotive, shipbuilding, military, and infrastructure industries. Today, our steel researchers, metallurgists, technicians, and engineers put on the garb of Prometheus as they continue to perfect different grades and specialty steel.

What are some of the aspects that go into steel processing?

Steel Grades Make Steel Processing Easier

In the modern world, there is a specialist for every job. It’s no different with steel. The “grade” of steel is a descriptor that identifies both the physical properties of the steel as well as its composition, among other descriptors. Currently, there are more than 3,500 grades of steel, each tailored towards a specific task. Of these, the grand majority were developed just in the last 25 years.

Thanks to this variety, steel processors can offer their clients the perfect “specialist” for the job.

Steel Processing: Earth-Friendly

No modern industry can claim to be for the benefit of mankind without being sustainable. For this reason, steel sustainability has made huge leaps in the last decades towards social responsibility.

Fortunately, as a material, steel is very compatible with sustainable goals. Steel is 100% recyclable. It is also very long-lasting and improves the performance of transportation vehicles, which makes for greener rides. Recently with the increased prominence of electric arc furnaces, more and more steel recycling has given new life to old steel. All this is done without reductions in quality or performance.

Creating Better Steel for Steel Processing

The creation of new grades of steel involves transformation of the chemical composition of steel alloys as well as using different physical processes to transform steel.

Steel can be categorized into four basic groups based on the chemical compositions:

Carbon steel
Alloy steel
Stainless steel
Tool steel

Check out this page to learn more about each of those categories.

Steel Processing: A Huge Enterprise

2020 saw the production of 1.88 billion metric tonnes (Mt) globally, which was actually 0.3% above the pre-pandemic 2019 production numbers. The worldwide COVID-19 pandemic caused many industries to grind to a halt, which – in turn, decreased the demand for steel. However, in 2022 demand promises to bounce back. The Worldsteel Association predicts that “steel demand will grow by 4.5% in 2021 and reach 1,855.4 Mt after 0.1% growth in 2020. In 2022, steel demand will see a further increase of 2.2% to 1,896.4 Mt. The current forecast assumes that, with the progress of vaccinations across the world, the spread of variants of the COVID virus will be less damaging and disruptive than seen in previous waves.”

The Slitting Line and Steel Slitting Process Explained

andre2021-06-24T18:47:26+00:00June 24th, 2021|News Blog, NMC Media|

Steel is an alloy of iron that is mixed with carbon which improves its strength and durability. Combine these properties with its low cost and you have a perfectly-suited alloy for a multitude of uses in various end applications, including (but not limited to) automotive, infrastructure, and appliance/HVAC.

Enter the role of steel processors. Steel processing companies like National Material Company provide manufacturers with the right steel material for their industry. This article will focus on the topic of steel slitting and how the slitting process works.

Steel slitting is a steel manufacturing process wherein a coil of steel is slit into the lengths and widths specified by the end application. This process requires machinery lines equipped with a decoiler, slitter, and a recoiler — to achieve the end product: slit steel coils, or “mults.”

An operator will feed the steel coil onto the uncoiler mandrel. The uncoiler unwinds the master coil, feeding it into the slitter head where the steel will be slit into narrow mults (strips) by rotary knives. The operator then inspects the individual mults to ensure the gauge width and edge condition meet required specifications. The mults will then travel through a looping pit to insure stress-free and camber-free recoiling of the slit material. Individual mults are then banded and packaged to specific customer requirements.

This process requires careful precision. Leading steel processing company NMC operates several steel service centers in the United States and Mexico using robust precision slitting machines equipped with advanced technology in software, tooling practices, and hardware. This helps National Material Company streamline their production and reduces their time to delivery. NMC thoroughly checks their equipment for alignment and regularly calibrates their machine line to help reduce scrap and overall cost.

National Material Company spent decades perfecting the art of steel processing to provide only the best to their clients, earning their position as a top steel processor. NMC guarantees top tier quality for all of your steel supply needs, and they also offer a wide variety of steel processing capabilities.

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.
