耐硫酸腐蚀的特种钢阀门

Sulphuric Acid Corrosion-Resistant Special Stainless Steel Valve

介绍N9不锈钢的物理、机械性能和抗腐蚀性能;详述用N9不锈钢生产阀门时,在冶炼、铸造、机加工等方面的操作要点。现场使用表明,N9不锈钢阀门有良好的抗硫酸、磷酸腐蚀的性能,其寿命比普通不锈钢高三倍以上。

The physical and mechanical properties and corrosion resistance of N9 stainless steel are described, along with processing consideration -n smelting, casting and mechanical work of it for valve manufacture. The industrial application showed that N9 stainless steel valves were rather resistant to corrosion of sulphuric acid and phosphoric acid, giving a service life over 3 times longer than ordinary stainless steel ones.
