200 series Stainless Steel came into existence due to shortage of Nickel. 300 Series Stainless Steel has some Nickel content in it. This Nickel content is replaced by Manganese and Nitrogen in 200 series Stainless Steel. This substitution obviously brings about a cost advantage. Also, with all the basic composition remaining the same, 200 Series has all the properties of 300 Series Stainless Steel. These properties along with cost advantage make 200 Series a good substitute for 300 Series Stainless Steel.

The method of production for 200 Series is same as 300 Series Stainless Steel. Same equipments and similar annealing temperature is used in the production process. Further, the composition is also same except that the costlier Nickel is replaced by cheaper Manganese and Nitrogen. This helps 200 Series in getting similar properties as 300 Series and hence it performs at par with 300 Series Stainless Steel with cost advantage.

One important question that may arise is that whether quality is hampered by changing the composition? The answer is a clear no; this small change in composition does not affect the quality. Stainless Steel of 200 Series exhibits good strength and formability. It possesses good corrosion resistance properties. These grades have austenitic structure similar to 300 series Stainless Steel. Austenitic structure confers valuable properties, which enables it to be cold worked, drawn and deformed into any shape based on the requirement. Austenitic stainless steels have good resistance to corrosion and oxidation; hence it can be used for variety of applications including handling of chemicals and in processing industries. They are not magnetic but austenitic hence difficult to differentiate from 304 Series.
