Product details
High strength quenched and tempered steel for welding structure The quenched and tempered steel for welding structure is the killed steel after fine grain treatment.
Welding structure with high strength quenched and tempered steel, according to its minimum yield point stress is divided into 420, 460, 500, 550, 620 and 690MPa six strength grades, each strength level and according to its impact toughness is divided into A, D, E, F four grades
Product information:
The grade of high-strength quenched and tempered steel for welding structures consists of a letter of impact toughness grade + a number of yield strength grade (three digits).
Impact toughness grade letters and meanings:
A -- Impact toughness grade at 0℃
D -- Impact toughness grade at -20℃
E -- Impact toughness rating at -40°C
F -- Impact toughness rating at -60°C
Yield Strength Rating Number (three digits) Indicates minimum yield stress value (MPa)
