CG Steel provides Din17155 steel plate and equivalent grades to meet customer needs. The DIN 17155 standard, a former German specification for gas cylinders, gas vessels, and pressure vessel plates, has been outdated. This specification, in conjunction with the BS standard, has been succeeded by EN 10028. Given its historical significance and continued demand, CG Steel is equipped to manufacture steel plates and sheets in accordance with this specification.

DIN17155 HII stands out as a widely favored steel grade for gas cylinder manufacturing, offering excellent welding performance. Welding is carried out in compliance with pressure requirements. Other grades such as HI, 17Mn4, etc., can be substituted with various alternative standards.
