EN 10149-2 Standard of steels

High yield strength steels under EN 10149-2 are mostly thermomechanically rolled. Has a good cold forming performance, weldability and so on. Such steel is usually used for load-bearing cold forming components, such as: steel frame, bearing beam and piping systems, the use of heat treatment should be avoided and high temperature environment, high temperature will reduce the yield strength of steel itself.
