HI this material is mainly used to fabricate boiler and pressure vessel. So ,same the other boiler and pressure vessel using steel plate, this kind of steel has the good grain and Mechanical properties. It's yield strength is around 245 MPa.HI tensile strength is from 360 MPa to 450 MPa. (different min strength point at the different thickness.) More detailed information about DIN 17155 HI steel Mechanical Properties , please refer to the following table:
