Description

S890QL1 is a high strength low alloy steel plate with Quenching and Tempering Steel,which is in EN 10025-6 technical delivery conditions for flat products of high yield strength structural steels in QT delivery condition.
S890QL1 is a water-quenched and tempered fine-grained structural steel with a minimum yield strength of 890MPa.The low temperature impacting test for high strength steel plate S890QL1 should be done at minus 60 centigrade.

S890QL1 Grade Designations

S=structural steel,

890 =minimum yield strength of 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.
