为了满足化肥工业用设备对高温、高压、抗氢氮氨介质腐蚀的要求,经过几年试验,已成功地研制出一种新型材料—10MoWVNb钢。该钢经有关钢厂批量试生产证明,在现有冶炼设备条件下,具有工艺性能稳定,无特殊要求,材料综合性能和可焊性良好的特点。使用证明,10MoWVNb钢优于目前化工部门使用的10GrMo910和17Gr_3MoWVA抗氢钢的水平,满足了化工合成氨中置式锅炉等设备抗氢、氮、氨用材的要求,并有着广阔的发展前景。 1.概述金属材料在化工生产设备系统中的高
In order to meet the high temperature, high pressure and anti-ammonia nitrogen medium corrosion requirements of fertilizer industrial equipment, after several years of experiments, a new type of material, 10MoWVNb steel, has been successfully developed. The steel by the relevant steel batch trial production proved that the existing smelting equipment under the conditions of a stable process performance, no special requirements, the overall performance of materials and weldability good features. Proof of use, 10MoWVNb steel superior to the current chemical industry 10GrMo910 and 17Gr_3MoWVA resistant to hydrogen steel to meet the chemical ammonia in the home boiler and other equipment against hydrogen, nitrogen, ammonia timber requirements, and has broad prospects for development. 1.
