Narrow & Oscillate Steel Coil Grades
Modern steel coil grades offer a large range of properties that make stronger, harder, or even more lightweight parts. Resistance to weathering is obtained through steel chemistry and through coatings on top of the steel. The steel industry is constantly doing research to develop steel coils that are simultaneously stronger, more formable, and more corrosion-resistant than previous grades. As a steel coil distributor, we are proud to offer these new narrow & oscillate steel coil and grades. Talk to us about which of these new steel coprovide the most economical combination of strength, ductility, and corrosion-resistance for you.

How Do I Select the Most Appropriate Steel Grade?
In selecting a steel grade for your application, it is important to keep a few factors in mind, namely: strength, formability, corrosion resistance, weight, chemistry, cost, and recommended uses of that steel. Your need and which of these factors is most important to you will determine the specific grade. Whether you need a steel that is more formable and you can sacrifice on strength, or you need a steel that is highly corrosion resistant but less formable, we can help you find the perfect grade.
Steel strength is measured as a force per unit area to stretching (Yield Strength) or breaking (Tensile Strength), in kilo(1000)-pounds per square inch (ksi), or Mega-Pascal (MPa). 1 ksi is equivalent to 6.9 MPa.
Formability is defined as how much you can stretch the surface before cracks appear and is measured as the % Elongation.
Siegal Steel is happy to personally guide you through the steel selection process. However, should you like to explore on your own, we recommend starting with Commercial Steel. This is a low carbon steel with good strength and formability. It is easy to machine and fabricated, plus it can be securely welded.
What Causes Defects in Steel?
In the process of making steel, it is first melted to form molten steel. Once in this state, elements like sulfur are removed, while elements such as vanadium and boron may be added. The second step involves the addition of elements such as silicon and aluminum. These elements are unique in that they combine with oxygen atoms, forming compounds with high melting temperatures. The addition of these elements is crucial to ensuring oxygen doesn’t form compounds that may melt when the steel is heated for rolling. Both of these types of compounds can remain in the steel as microscopic particles or “inclusions.” The current technology and advancements in steel making have reduced the size and frequency of these inclusions.
After all the necessary elements are added and removed, the molten steel is then cast. Immediately following casting it is either rolled or completely cooled and reheated later for the rolling process. During the casting and rolling process it is possible that surface defects may be introduced. However, these defects that could cause surface cracking and tearing are removed. Siegal Steel will help you select a steel grade that economically meets the internal and surface requirements for your product.
