Offer Ability:5 000MT/Per Month EN10025-3 S420NL alloy special structural steel plates
EN10025-3 S420NL alloy special structural steel plates are European standard high strength steel. The comprehensive mechanical properties of S420NL steel plates are especially high after normalizing or normalizing plus tempering. In grade S420NL,
NL means the steel need to do impact absorption test in a low temperature environment of 50 degrees below zero and the impact value is not less than 27J.
