UNS S32550 Super Duplex Seamless Pipe 24% Cr Corrosion Resistance 1.4507
S32550 / 255 Duplex Stainless Steel Seamless Pipe 24%Cr Corrosion resistance 1.4507
S32550 / 1.4507 / 255 24% chromium duplex stainless steel
S32550 / 255 Duplex Stainless Steel processing performance:
Because S32550 / 255 Duplex Stainless steel contains copper, the hot working temperature of this steel should not be too high, and the final forging temperature is generally about 980 ° C. The steel can be sheared, stamped, stamped, etc., but due to the high strength of the steel, the cold working deformation force is 2 to 3 times higher than that of austenitic stainless steel.
If the steel is heated to 200 ° C, the yield strength can be reduced by 25%, and the forming process can be easily performed. The steel can be welded by various protective welding, can be welded with other grades of duplex stainless steel, and can also be welded with dissimilar steel (non-stainless steel) or non-alloy steel.
