牌号 | C ≤ | Mn ≤ | P ≤ | S ≤ | Si ≤ | Ni | Cr | Mo | N |
317LN | 0.035 | 2.0 | 0.04 | 0.03 | 0.75 | 11.0 ~15.0 | 18.0 ~20.0 | 3.0 ~4.0 | - |
Remarks: X2CrNiMoN17 13 5 () is a stainless steel with excellent pitting corrosion resistance and crack corrosion resistance, and Mo plays an important role in it. Therefore, it must be noted that the Mo content in welding materials is higher than that of the base material. As for what welding material to use, I forgot for a moment. Uses: It is mostly used in chemical industry, petroleum, textile, paper-making equipment, pipelines, containers, etc. |
