摘要
试验研究了成分(%)为:0.39C,0.70Ni,16.73Cr,1.07Mo和0.53C,1.05Ni,16.87Cr,0.96Mo两种Cr17Mo型耐蚀塑料模具钢的淬回火组织、力学性能和耐蚀性能。试验结果表明,当Cr17Mo型钢中碳含量由0.39%提高至0.53%时,经1 060℃淬火,475℃回火后该钢的峰值硬度HRC值由46.5提高到53.4;两种试验钢在弱酸、氧化性酸和1%盐酸中均有较高的耐腐蚀性能。
The quenched and tempered structure, mechanical properties and corrosion resistance of two Cr17Mo type corrosion resistant stainless steels for plastic mould - 0.39C, 0.70Ni, 16.73Cr, 1.07Mo and 0.53C, 1.05Ni, 16.87Cr, 0.96Mo have been tested and researched. As the carbon content in Cr17Mo type steel increased from 0.39% to 0.53%, the peak HRC hardness value of steel quenched at 1 060 ℃ and tempered at 475 ℃ increased from 46.5 to 53.4; and the two test steels had better corrosion resistance in weak acid, oxidizing acid and 1% HCl.
