DIN17165 HII Steel plate for Boiler Pressure Vessel
HII steel plate, DIN17165 HII steel plate is a kind of material for boiler and pressure vessel steel. DIN17165 HII steel plate is characterized by a minimum yield strength of 185 - 265 MPa and by good weldability, so HII steel is mainly used for manufacturing boilers, pressure vessels and pipes transporting hot liquids. The followings are DIN17165 HII steel plate's Chemical composition and mechanical properties.

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 . DIN17155 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 This standard is no longer active and has been superseded along with the old British Standard by EN 10028, the new Euro Norm standard
