Grade HII steel
Grade HII steel is under DIN 17155 standard which is the German standard for pressure vessel steel. This standard is no longer active and has been superseded along with the old British Standard by EN 10028, the new Euro Norm standard. Our customers often search and make sales enquiries for Grade HII steel.
Grade HII steel
Because of Grade HII steel has many advantages, such as, a minimum yield strength of 185 - 265 MPa and good weldability, it has a much bigger market need.
