GH90高温合金弹簧丝材的试制

Trial-Production of GH90 High Temperature Alloy Wires

GH90高温合金弹簧钢丝采用固溶再经表面酸洗皮膜处理进行单道次大压缩率冷拉的生产工艺,可获得高强度、一定的韧性,一定的抗弯曲扭转能力,其产品满足质量要求。本文探讨了GH90合金弹簧钢丝的固溶处理、表面处理以及拉拔变形量和拉拔工艺。

Using the production process of solid solution ＋ surface pickling treatment ＋ cold drawing at a big reduction ratio in a single pass, the produced GH90 high temperature alloy spring wires axe demonstrating to have a high strength, a certain toughness, a certain bending and torsional resistance. The products meet the quality requirements. This paper discusses the solid solution , surface treatment and drawing deformation and drawing process of GH90 alloy spring steel wires.
