The successful application of 400 series stainless steel in India is because it is possible to replace 304 stainless steel in some specific applications. and nitrogen) to replace some or all of the nickel to produce lower nickel content austenitic stainless steels.
The disadvantages of this series of materials are:
The 18% chromium content and the low nickel content are not balanced and ferrite is formed. For this reason, the chromium content in the 200 series stainless steel is reduced to 15% to 16%, and in some cases to 13% to 14%. Its corrosion resistance is not comparable to 304 and other similar steels. Furthermore, manganese and in some cases copper reduce the effect of repassivation under acidic conditions common to corrosion sites in deposit zones and crevices.
2B BA No.1 ASTM A240 430 410S 409 Stainless Steel Plate will fail approximately 10-100 times faster than 304 stainless steel under these conditions. Also, the residual sulfur and carbon content of these steels is often not controlled during production, and the material cannot be traced back to its source, even when the material is recycled.
