ASTM A514 - Grade B Construction Alloy Steel - Plates

“T-1” type A steel can be furnished to the following heat-treated mechanical properties.


Thickness 3/16” to 3/4” incl. Over 3/4” to 1 1/4” incl.
Yield Strength, Ext. under load (min) 100000 psi 100000 psi
Tensile Strength 115000 to 135000 psi 115000 to 135000 psi
Elongation in 2”, % (min) 18 18
Reduction of Area, % min 40 50

For maximum resistance to impact abrasion, “T-1” type A steel may be ordered to a minimum hardness of 321 BHN, in which case all other mechanical properties are waived.
