ACID DEW POINT CORROSION-RESISTANT STEEL AND EXHAUST GAS FLOW PATH CONSTITUENT MEMBER |
摘要 |
A steel has improved sulfuric acid dew point corrosion resistance without relying upon the addition of Sb and can have improved hydrochloric acid dew point corrosion resistance. The acid dew point corrosion-resistant steel includes from 0.005 to 0.200% of C, from 0.20 to 0.80% of Si, from 0.05 to 1.50% of Mn, from 0.002 to 0.020% of P, from 0.005 to 0.015% of S, from 0.10 to 0.50% of Cu, from 0.05 to 0.30% of Ni, from 0.005 to 0.100% of Al, and 0 or more and less than 0.010% of Mo in terms of % by mass, with the balance being Fe and impurities. In the case of attaching great importance to hydrochloric acid dew point corrosion resistance, it is desirable to control the Mo content in the foregoing steel to from 0.005 to 0.030% by mass. |

1. An acid dew point corrosion-resistant steel comprising from 0.005 to 0.200% of C, from 0.20 to 0.80% of Si, from 0.05 to 1.50% of Mn, from 0.002 to 0.020% of P, from 0.005 to 0.015% of S, from 0.10 to 0.50% of Cu, from 0.05 to 0.30% of Ni, from 0.005 to 0.100% of Al, and 0 or more and less than 0.010% of Mo in terms of % by mass, with the balance being Fe and impurities. |
