S32550 stainless steel pipe can be welded by GTAW, SMAW and GMAW methods, and can also be welded with other duplex stainless steel pipes or dissimilar steels, such as 316, carbon steel, etc. The welding process is similar to that of austenitic stainless steel, but in order to improve the weld metal for corrosion resistance, generally larger heat input is used, and heat treatment is usually not required after welding.

When using the SMAW method for welding, it is necessary to use a core with a higher nickel content (Ni about 70%) than the base metal to increase the amount of austenite in the weld and make the weld metal have the same plasticity as the base metal.

S32550 stainless steel pipe can be sheared, stamped, molded, etc. Due to the high strength of the steel, the deformation begins to require 2 to 3 times the external force to be deformed than the austenitic stainless steel. If heated to 200°C, the yield strength of steel can be reduced by 25%, which is beneficial to the forming of steel and reduces the resilience of steel.

The hot working and hot forming of S32550 stainless steel pipe is the same as that of duplex stainless steel containing 25% Cr and molybdenum. However, because the steel contains copper, it is not suitable to use too high hot working temperature. The final forging temperature is generally controlled at about 980℃ The hot working temperature range of steel is narrow.

S32550 stainless steel pipe has good mechanical properties and local corrosion resistance, especially its abrasion resistance is better than ordinary stainless steel, and it is easier to weld and form. It is precisely because of this versatility that the steel has a very wide range of applications. Wide, suitable for the manufacture of various industrial equipment and components. It is still a kind of duplex stainless steel used in large quantities, especially in the seawater environment. It is suitable for ship propellers, shafts, rudders, Submarine seals, etc.

S32550 stainless steel pipe is not only used in the marine industry but also in the chemical industry, petrochemical industry, oil and natural gas, pulp and paper, environmental protection, wet-process phosphoric acid and metal processing industries. It is mostly used in scrubbers, dryers, cyclones, agitators, Centrifuges, pumps, valves, fasteners, etc.
