低淬透性钢58(55 1050—74)及整体加热表面淬火方法,在汽车和拖拉机零件的制造中已被广泛应用于制作重载零件。用该钢制作的零件经整体——表面淬火,与合金钢制作的零件经常规热处理(调质、正火、渗碳、表面感应淬火)相比,具有较高的强度。用这种材料和热处理方法,可节省昂贵的合金钢,并可降低能耗,摒弃 Low Hardenability Steel 58 (55 1050-74) and Whole Heating Surface Hardening are widely used in the manufacture of automotive and tractor parts for the manufacture of heavy-duty parts. Parts made from this steel, as a whole - are surface hardened and have higher strength than those made from alloy steel by conventional heat treatment (tempering, normalizing, carburizing, surface induction hardening). With this material and heat treatment methods can save expensive alloy steel, and can reduce energy consumption, to abandon
