UNS S30815 stainless steel plate supplier, UNS S30815 plate, 253MA steel plate, 1.4835 Duplex steel sheet, Duplex steel S30815 sheet, Duplex steel 1.4835 sheet, 253MA Duplex steel plate and sheet manufacturer in HT PIPE.

Stainless steel 253MA has high carbon content so is highly susceptible to sensitisation from service exposure or welding. Although not designed for aqueous corrosion resistance, the high chromium and nitrogen contents give it a pitting resistance approximating that of 316. Solution Treatment (Annealing) - Heat to 1050-1150°C and cool rapidly. To achieve maximum creep strength in service it is recommended that the material be solution treated after 10-20% cold work. It cannot be hardened by thermal treatment. It provides excellent weldability, 253MA welding with Grade 22.12HT rods or electrodes is pre-qualified by 1554.6. If lower creep strength can be tolerated Grade 309 fillers can be used.
