Super duplex stainless steel woven mesh is a high-performance alloy material that combines austenitic-ferritic duplex structures with molybdenum, offering excellent corrosion resistance and mechanical properties. According to chemical composition, it is mainly divided into two types: UNS32750 and UNS31803:
Chemical Composition
| Steel Grade | C ≤ | Mn ≤ | Si ≤ | S ≤ | P ≤ | Cr | Ni | Mo | Cu ≤ | N |
|---|---|---|---|---|---|---|---|---|---|---|
