Propertise of S.S.200
Chemical Properties ::
The chemistry offered is derived form the parent AISI 200 series, with suitable technical modification to achieve the final properties in a cost effective manner as compared to the existing 304 Grade SS. Literature survey reveals that AISI 200 series were developed in 1950's in the United States, that development was strictly by the nickel shortage which was prevalent at that time. The composition of these Steels varied widely with carbon ranging from 0.08 to as high as 0.25%, nickel from 0.3 to around 7 % , Nitrogen from 0.10 to 0.4% with a chromium level of 14 to 18%. The technical theme behind development of these grades was mainly to substitute the costly nickel with manganese and nitrogen to achieve the austenitic structure by controlling the ratio of austenite forming elements and ferrite forming elements (Ferrite Factor) The drawbacks with these steel were higher carbon (>0.1%) and higher nitrogen resulting into poor formability characteristics. With these backgrounds a new chemistry was designed in which the carbon is controlled to a maximum level of 0.09% and nitrogen up to 1700ppm to aid in formability addition Copper is made so that the work hardening rate is controlled. Thus the optimized chemistry offered by us is

Corrosion Properties ::
Considering that the components manufactured out of these sheets are used in normal atmospheric condition chromium level 14.5% to 25.5% is quite to resist pitting corrosion. Experiment carried out showed the following result
Kitchen utensils and cutleries retained their surface finish and luster similar to 304 Grade
Laboratories scaled experiments carried out under different media revealed the following data
