Stainless steel material is selected from 304 stainless steel:
1.304L is more corrosion resistant, 304L contains less carbon.
2.304 has a wide range of uses, has good corrosion resistance, heat resistance, low temperature strength and mechanical properties; good hot workability such as stamping and bending, no heat treatment hardening (non-magnetic, use temperature -196°C~800°C).
3. 304L has excellent resistance to intergranular corrosion after welding or stress relief; it can maintain good corrosion resistance without heat treatment, and its use temperature is -196°C-800°C.
