ASTM A514 Grade J is an alloy steel plate that's quenched and tempered for extra strength. It's part of the A514 group, with metals like nickel and molybdenum to make it tough. The ASTM A514 standard covers strong steel plates for welding in tough spots. Grade J is for thin plates, with high yield strength.
