Stainless steel 310S (also known as 0Cr25Ni20 or S31008) is a high alloy austenitic chromium-nickel stainless steel known for its excellent high temperature resistance, oxidation resistance and corrosion resistance. It is widely used in industrial equipment in extremely high temperature and corrosive environments.

3. Advantages and limitations
Advantages
✅ Ultra-high temperature stability (still usable at 1200°C)7.
✅ Excellent oxidation and corrosion resistance, suitable for harsh environments24.
✅ Good mechanical strength, not easy to deform at high temperatures59.
✅ Non-magnetic, suitable for electromagnetic sensitive equipment8.
Limitations
❌ High processing difficulty: high hardness makes cutting and cold forming difficult8.
❌ High cost: high nickel content, the price is 3-4 times that of 304 stainless steel8.
❌ Limited low temperature applicability: although it can be used at -450°F (-268°C), the strength decreases5.
