DIN 17135A St 45 steel steel is a weldable pressure vessel and boiler steel grade used by the world's industrial fabricators.
The material, DIN 17135A St 45 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.
We can produce DIN 17135A St 45 steel accord to many foreign Standard directly---ASTM/ASME /JIS/DIN/BS/EN/AISI
Providing DIN 17135A St 45 steel cutting and welding service according to your drawing.
