≤8 | 390-550 | ≥245 | ≥25 |
4.Corrosion resistance
In the medium temperature and concentration of sulfuric acid, Nd steel passivation occurs due to dissolution, the surface of the steel formed a layer rich in Cu,Cr,Sb and other alloy elements of the passivation layer, and has a high sulfuric acid corrosion resistance.
