HIGH SILICON CHROMIUM NICKEL STEEL AND A METHOD OF USING IT TO INHIBIT CORROSION OF APPARATUS BY STRONG NITRIC ACID |
| 摘要 |
A high-silicon-nickel-chromium steel resistant to concentrated nitric acid with a good workability and a good weldability, comprising carbon in an amount of not more than 0.03% (C</=0.03%), silicon in an amount of from more than 5% to not more than 7% (5%<Si</=7%), manganese in an amount of not more than 10% (Mn</=10%), chromium in an amount of from not less than 7% to not more than 16% (7%</=Cr</=16%), nickel in an amount of from not less than 10% to less than 19% (10%</=Ni</=19%), and the balance being iron and inevitable impurities, percentages being by weight. |
