DIN 17155 HII steel plate/sheet for gas cylinders and gas vessels
HII steel plate/sheet, DIN 17155 HII steel plate/sheet, under DIN 17155 standard, we can regard HII steel plate/sheet for gas cylinders and gas vessels.
HII steel plate/sheet is one mainly of Steel for gas cylinders and gas vessels.DIN 17155 HII steel grade is for heat resistant plates in grade HI, HII, 17 Mn4, 15 Mo3, 13CrMo44, 10CrMo910 and AST41 steel grade.DIN 17155 HII 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 This standard is no longer active and has been superseded along with the old British Standard by EN 10028, the new Euro Norm standard.
