A633 High Strength Steel Plate
A633 is an American Standard low alloy plate that is a normalized high strength structural steel, ideal for welding, riveting or bolting.
There are four grades: A, C, D, and E.
Typical applications is in the areas of construction equipment, offshore support structures, and other construction areas where additional strength is critical.
gnee Steel stocks and supplies the ASTM A633 structural steel plate, which offers stronger notch toughness.
ASTM A633 structural steel plate Overview:
Normalized high-strength structural steel grade ideal for welding, riveting or bolting.
Available in four grades: A, C, D and E.
Exhibits greater notch toughness in low ambient temperatures than compared to as-rolled materials of similar strength.
Charpy test requirements for specific zones and climates may be requested.
May be multiple-certified as API or ABS specifications on Mill Test Report, but guaranteed to be certified to meet ASTM A633 standards.
