DIN 17155 HI steel always finds their own broad application areas in manufacturing pressure vessels, boilers and hot liquids transporting pipes. DIN 17155 HI steel has good weld-ability and excellent strength.
DIN 17155 HI is the German standard for pressure vessel steel. DIN 17155 HII has been superseded by the new Euro standard EN 10028, but our customers often search and make sales enquiry for this steel grade.
