【摘要】 ND钢具有很高的抗硫酸露点腐蚀能力，并具有SO2＋Cl-及Cl-溶液中的高耐腐蚀性能，与20g相比，还具有较高的中温（200℃～500℃）力学性能，故在一定范围内可替代20g，Cotren．Sten．CRI普通304及316不锈钢。更多还原

【Abstract】 The paper introduces that ND steel has high ability of sulfuric acid slution corrosion resistance under the condition of fow dense and high temperature. Compared with 20g steel. it has higher mechanical properties on the temperature range from 200℃to 500℃. To a certain extent we can substitude ND steel instead of Steel such as 20g, Corten.
