321 Stainless steel chemical composition

321 Stainless steel chemical composition

321 stainless steel is a derivative of 304 stainless steel, the difference in corrosion resistance is not large, but in the heat condition of 500-600 degrees Celsius, most of the 321 stainless steel is used, because 321 stainless steel has titanium (Ti) as a stabilizing element, so that it effectively controls the formation of chromium carbide, but also heat strength steel. The 321 stainless steel has better resistance to intergranular corrosion and high temperature strength, so it can be used to manufacture wear-resistant acid containers and the lining and transportation pipeline of wear-resistant equipment. However, Wuxi Zhongxingeide does not recommend 321 stainless steel as decorative parts.

321 stainless steel chemical composition is as follows:

C (carbon) : ≤0.08;

Si (Silicon) : ≤0.75;

Mn (manganese) : ≤2.00;

P (P) : ≤0.045;

S (sulfur) : ≤0.030;

Ni (nickel) : 9.00~12.00;

Cr (Chromium) : 17.00~19.00;

N (nitrogen) : ≤0.10;

Ti (titanium) : ≥5XC.
