PRODUCT CENTER
ASTM A573/A573M grades are divided into: 58, 65, 70, and the steel coils are suitable for structural grade carbon-manganese-silicon steel coils in three tensile strength ranges. ASTM A573/A573M steel coils are mainly used for important purposes of improving notch toughness at room temperature.
A588 Low Alloy Structural Steel Coil
ASTM A588 is a high strength low-alloy structural steel specification with higher strength and improved atmospheric corrosion resistance. It covers Grade A, Grade B, and Grade K. Grade A, B is the specification for atmospheric corrosion structural steel of High-Strength Low-Alloy, yield strength minimum 50 ksi 345 Mpa.
ASTM A633 is a high-strength / low alloy grade produced in the normalized condition. It is predominantly used in environments where superior notch toughness is needed at low ambient temperatures. Grades are divided into A, C, D, E.
A high-strength, low-alloy, hot-rolled structural steel coil utilized in structural applications where lighter weight and improved formability is critical. Applications include: truck frames, crane booms, and rail car components. Made to Grades 50, 60, 70 and 80, the grade designating the yield strength.
A709 Carbon Structural Steel Coil
The ASTM A709 is the Standard Specification for Structural Steel for Bridges and encompasses carbon, high-strength low-alloy, and quenched and tempered alloy steels used as structural coils in the construction of bridges. It following five grades of A709; 36, 50, 50W, HPS 50W and HPS 70W.
Cold rolled steel is rolled at room temperature and then rolled again below its recrystallization temperature. This process enables better control over finished product shape, thickness, dimensions, and a more consistent finish.
SAE/AISI 4000 Series Alloy Coil
Alloy Steel is a combination of Iron, Carbon, and various other elements like Nickel, Chromium, and Molybdenum. The additional elements make alloy steel unique and enhance the already excellent physical properties like strength, toughness, and corrosion resistance to a new extreme.
