Stainless steel 200 series

Stainless steel of the 200 seriesare chromium-manganese-nickel austenitic steels, similar in their properties to AISI 301. In the annealed state, they completely retain the austenitic structure. After cold deformation and strengthening, these steels are applicable in those cases where it is necessary to take into account the load factors in the structures. The combination of a high content of manganese and nitrogen, as well as a sufficient amount of nickel, gives this alloy excellent strength, rigidity at cryogenic temperatures and ambient temperatures. Steels of the 200 series have good oxidation resistance, comparable to AISI 301 at temperatures up to 800 ° C.

Steels of the 200 series are used in many areas where AISI 301 and AISI 304 steel grades have traditionally been used. Alloys of this series are relatively economical compared to austenitic grades of the 300 series. At the same time, they have similar formability and weldability. They have good resistance to moderately aggressive environments. They can be welded by all traditional methods applied to grade 304 austenitic stainless steel. Filler wire or electrodes made of ordinary chromium-nickel steel of the 300 series can be used. The sensitivity of these steels to intercrystalline corrosion in the heating zone during welding is similar to that of AISI 304. Steels of the 200 series are very strong and ductile. They are easily subjected to cold drawing, bending, drawing and twisting.
