Product Description


SUS321 Stainless Steel Characteristics:
 Add Ti to  enhance intergranular corrosion resistance, not recommended as decorative  components.

Corrosion Resistance
 SUS321, SUS347  and SUS348 are stainless steel with titanium, niobium and niobium stabilized,  suitable for welding components used in high temperature.348 is a kind of  stainless steel which is suitable for nuclear power industry, and has certain  limitation on the amount of tantalum and drill.
