HSLA Structural Quality

       A572 Gr50, 60, 65

       A572 Gr42

       A633

       A607 Gr50, 65

 

HSLA structural quality steels are hot-rolled carbon-based steels with small additions of alloy. This combination of carbon and alloy provides a substantially increased strength and toughness compared to general-purpose, low-carbon grades. By comparison, this category of steel offers improved strength-to-weight ratios.

 

HSLA Structural Quality With Improved Formability

       A656 Gr80

       A715 Gr50

       100 KSI as rolled

       130 KSI as rolled

 

Steels produced to this standard are hot-rolled carbon-based steels with small additions of alloy. The combination of carbon, low alloy, and killed steel fine grain melt provides increased strength, toughness, and improved strength-to-weight ratio over general-purpose, low-carbon grades–plus improved formability.

 

HSLA Structural Quality With Atmospheric Corrosion Resistance

       A606 Type 4

       A588/242

 

Steels produced to this standard are hot-rolled carbon-based steels, which may have the addition of alloying elements, and are usually specified with 0.20 minimum copper. This combination of chemical elements provides a substantially increased strength-to-weight ratio, toughness, and improved resistance to atmospheric corrosion.
