DIN HII steel is a weldable pressure vessel and boiler steel grade used by the world's industrial fabricators.
The material, DIN HII steel is ideally suited for elevated temperature service, is commonly found in the oil & gas, petrochemical and chemical industry. This European standard grade steel has replaced the BS1501 and DIN17155 specification.
Providing DIN HII steel cutting and welding service according to your drawing.
