适用范围
This document specifies the technical delivery requirements for — semi-finished products, hot formed (e.g. blooms, billets, slabs) (see NOTE 1), — bars (see NOTE 1), — wire rod, — finished flat products, and — hammer or drop forgings (see NOTE 1) manufactured from the case-hardening non-alloy or alloy steels listed in Table 3 and supplied in one of the heat-treatment conditions given for the different types of products in Table 1 and in one of the surface conditions given in Table 2. The steels are, in general, intended for the manufacture of case-hardened machine parts. NOTE 1 Hammer-forged semi-finished products (blooms, billets, slabs, etc.), seamless rolled rings and hammerforged bars are covered under semi-finished products or bars and not under the term “hammer and drop forgings”. NOTE 2 For International Standards relating to steels conforming with the requirements for the chemical composition in Table 3, however, supplied in other product forms or treatment conditions than given above or intended for special applications, and for other related International Standards, see the Bibliography.

热处理原理与常见种类(二)

3、稳定工件尺寸    4、对于退火难以软化的某些合金钢,在淬火(或正火)后常采用高温回火,使中碳化物适当聚集,将硬度降低,以利切削加工。    补充概念    1、退火:指金属材料加热到适当的温度,保持一定的时间,然后缓慢冷却的热处理工艺。常见的退火工艺有:再结晶退火、去应力退火、球化退火、完全退火等。...

模具热处理变形与开裂的预防措施

3、合理制定技术条件合理制定技术条件(包括硬度要求)是防止淬火变形、开裂的一条重要途径。局部硬化表面硬化就可以满足使用要求的,尽量不要整体淬火。对于整体淬火模具,局部可放宽要求的,尽量不要强求一致。对于成本高或结构复杂的模具,当热处理难以达到技术要求时,应更改技术条件,适当放宽那些对使用寿命影响不大的要求,以免因多次返修而造成报废。...
