TStE355 steel

 DIN TStE355 ,A pressure vessel steel grade with good weldability and high resistance to brittle cracking, DIN TStE355 steel is used by the world's fabricators for the manufacture of pressure vessel tanks for the storage of pressurised gases.
DIN TStE355 steel plate/sheet, under DIN standard, we can regard DIN TStE355 for boilers and Pressure Vessels steels.DIN TStE355 steel is for boilers and Pressure Vessels steels,it is a normalized steel plate and sheet which is mainly used for building pressure vessels and boilers and pipes for hot liquid.
