High Strength Low Alloy (HSLA) steel is very strong, highly formable, and easy to weld.
High Strength Low Alloys 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.

What is HSLA Steel Recommended For?
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.
Strength, Yield Strength ksi(MPa), Tensile Strength ksi(MPa): Stronger, 35-100 (240-690)
For higher strength and lower weight, consider Advanced High Strength Steels
Formability: % Elongation: Good, 10 – 24 % depending on strength level
For better formability consider Deep Drawing Steel
Chemistry – up to several percent of Mn, Si, Cr, Mo.
- Cost – Medium
