S890QL1 high-strength plate is a high-strength structural steel plate that can withstand the challenges of high-strength and high-load working environments. S890QL1 steel plate has superior strength, plasticity and toughness and is an ideal material for heavy machinery, construction projects and various important industrial equipment.
S890QL1 is a water quenched and tempered, fine grained structural steel with minimum yield strength of 890MPa,mainly used as low temperature resistant, high strength of key parts, construction machinery, mining machinery structure, etc.
S890QL1 Grade Designation
S =structural steel
890= the minimum yield strength 890Mpa
Q=quenched and tempered.
S890QL1 steel could be through the -60 temperature impact and the energy is 30J, which could be used in lower temperature environment.
