【摘要】 本文主要针对桑塔纳轿车发动机部件用CH13钢金属铸模的国产化,对CH13铜的若干性能进行了试验研究。结果表明CH13钠和H13钢有相近的强度,回火稳定性优于H13钢,但塑性较H13钢低。更多还原

【Abstract】 In order to realize thc domestic production of CH13 steel molds, which will be used to make engine parts for Santana cars, some properties of CH13 steel were investigated. Results showed that the strength of CH13 steel was similar to that of H13, the tempering stability of CH13 was higher than that of H13 steel, but the plasticity of CH13 was lower than that of H13 steel.更多还原
