A633 grade E steel plate belongs to the American standard low-alloy high-strength structural steel plate. A633 grade E steel plate has high strength, high toughness, good weldability and cold formability. A633 grade E steel plate has a lower cold-brittle transition temperature. If it is applied to large welded components, it is also required to have high fracture toughness.
The grade of A633 grade E steel plate indicates:
"A": Indicates the implementation of American standard high-strength board;
"633": indicates the yield strength of the steel plate is 633, the unit is MPa;
"E": Indicates the quality grade of the steel plate, impact test at -40°C
A633 gradeE steel plate implementation standard: implementation of ASTM (American Standard) standard.
Delivery state of A633 grade E steel plate: delivered in normalized state, can add flaw detection standard requirements, flaw detection grade requirements, alloy element composition control requirements, etc. A633 gradeE steel plate thickness direction performance requirements: Z15, Z25, Z35.
