High Strength Low Alloy (HSLA) Structural Steel Plates

High Strength Low Alloy (HSLA) structural steel plates are very strong, highly formable, and easy to weld. 

They resist corrosion and rust better than plain-carbon steels. HSLA Steels are made to provide specific mechanical properties rather than specific chemical compositions. They are used in cars, trucks, cranes, bridges, and other structures where their high strength-to-weight ratio is most cost-effective.

HSLA Steels resist corrosion and rust better than plain-carbon steels. Use HSLA steels in cars, trucks, cranes, bridges, and other structures where their high strength-to-weight ratio is most cost-effective.

HSLA steels are available in a series of grades, designated by their tensile strength.  As shown in this graph, there is a trade-off between Strength and Formability.

Figure. Elongation of HSLA steels decreases as Yield Strength increases

HSLA – F grades are available with about 10% higher Formability at each Strength.

We will be glad to help you select the exact grade for your needs.
