The Corrosion Resistance and Heat Resistance of 321S32 Steel Grade

[ad_1] The 321S32 steel grade is a stainless steel alloy with good corrosion resistance and heat resistance properties. It contains the following chemical composition:

– Iron (Fe): balance
– Chromium (Cr): 17-19%
– Nickel (Ni): 9-12%
– Manganese (Mn): max 2%
– Silicon (Si): max 1%
– Phosphorus (P): max 0.045%
– Sulfur (S): max 0.03%
– Carbon (C): max 0.08%
– Nitrogen (N): max 0.10%
– Titanium (Ti): 5x(C+N)-0.70% maximum

The 321S32 steel grade exhibits improved intergranular corrosion resistance and resists polythionic acid stress corrosion cracking. It also has excellent high-temperature strength and good oxidation resistance. Additionally, this grade is easy to machine, stamp, and weld. These properties make it suitable for applications in industries such as aerospace, chemical processing, and high-temperature environments.
