High Quality 
Mature Technical 
Safe and 
1, Normalized high-strength structural steel grade ideal for welding, riveting or bolting.
2, Available in four grades: A, C, D and E.
3, Exhibits greater notch toughness in low ambient temperatures than compared to as-rolled materials of similar strength.
4, Charpy test requirements for specific zones and climates may be requested.
5, May be multiple-certified as API or ABS specifications on Mill Test Report, but guaranteed to be certified to meet ASTM A633 standards.
