碳钢弹簧钢丝常用铅浴淬火工艺，可获得非常细小的珠光体组织（索氏体），对于改善深度拉拔性能及弹簧性能都是有益的，铅浴的替代工艺流化床还未推广，目前在一些小直径上有应用。合金钢丝一般采用退火热处理，使显微组织适应拉拔变形。不锈钢丝的热处理采用固溶处理，其目的也是改善组织以适应拉拔的需要。油淬火工艺用在成品钢丝上铜钟 一次性止血带 标志桩模具 钢丝轮 流水槽模具 防撞墙模具 检查井钢模具 不锈钢铸件 模锻件，采用感应加热或燃气、燃油加热炉，将钢丝加热至奥氏体化温度保温一段时间，淬火后再进行一次中温回火。虽然名义上叫油淬火，基本上都采用水淬火或加高分子材料的水淬火。
Lead bath quenching process is commonly used in carbon steel spring steel wire, which can obtain very fine pearlite structure (sorbite). It is beneficial to improve deep drawing performance and spring performance. The replacement process of lead bath fluidized bed has not been popularized, and it has been applied in some small diameter steel wires. The alloy steel wire is generally annealed to make the microstructure adapt to drawing deformation. The heat treatment of stainless steel wire adopts solution treatment, its purpose is to improve the microstructure to meet the needs of drawing. The oil quenching process is used on the finished steel wire. The steel wire is heated to the austenitizing temperature by induction heating or gas and oil heating furnace for a period of time. After quenching, the steel wire is tempered at medium temperature. Although it is nominally called oil quenching, it is basically water quenching or water quenching with polymer materials
