S890QL
S890QL is a structural steel grade with an even greater yield strength than S690QL. The material serves as a great option for procurers who wish to promote high strength in a cost effective way. Due to the characteristics of the steel, clients can use this material in numerous applications resulting in a leaner build whilst still maintaining great strength.
S890QL is a water quenched & tempered steel which complies with the EN10025:6:2004 specification.
Please refer to the technical details below referring to S890QL.
