A ST 52 steel plate, DIN17135 A ST 52 metal plate is a kind of materials for boiler and strain vessel metal. DIN17135 A ST 52 metal plate is characterised by a minimal yield strength of MPa and by good weldability, so A ST 52 metal is mainly used for manufacturing boilers, strain vessels and pipes transporting scorching liquids. 

1, According to German standard DIN 17100, St52 steel is split into St52 3U (1.0553) and St52 3N (1.0570 materials).
