摘要
通过试验研究对比了446与310S在浓硫酸中的耐蚀性能以及力学性能。研究表明:446具有优良的耐浓硫酸腐蚀性能和力学性能,在w(H2SO4)95%以上浓硫酸中的耐蚀性不低于甚至优于310S。铁素体不锈钢446可应用于干燥塔、吸收塔、低温位热回收塔、换热器以及泵阀管线等设备。
The corrosion resistance and mechanical properties in concentrated sulphuric acid of 446 compared with 310S was described. The results demonstrate that 446 is of excellent corrosion resistance in concentrated sulphuric acid and good mechanical properties,the corrosion resistance in concentrated sulphuric acid above 95% is no less than or even better than 510S. Ferritic stainless steel 446 can be used in the drying tower, absorption tower, low heat recovery tower, heat exchanger and valve piping and other equipment.
