摘要
介绍１７─７ＰＨ高｀强度不锈弹簧钢丝的优异性能，指出１７─７ＰＨ弹簧钢丝应力裂纹倾向大，生产难度高．通过调整钢的化学成分和改进冶炼、锻造、热轧、冷拉等工序的工艺可基本消除裂纹，但全面防止１７─７ＰＨ冷技裂纹还需深入研究．
The article introduces the excellent property of 17─7PH high strength stainless spring steel wire, indicates that this kind of steel wire has great tendency of producing stress crack, and that it has high degree of production difficulty.It can basically clear up the crack through regulating the chemical composition of steel and improving the technology of working procedure such as smelting, forging,hotrolling and cold-drawing etc,but it still need to make thorough research on overall preventing 17─7PH cold-drawing crack from producing.
