The drawing indicated " heat treatment HRC55"是指整体达到这个硬度还是表面达到
整体热处理和表面热处理用英语怎么说 本帖最后由 孤鸿踏雪 于 2012-2-19 10:16 编辑
图面显示为HRC55.整体热处理:bulk heattreatment;表面热处理:surface heat treatment。 Can you specify what kind of heat treatment used by the part? Is there any requirements in the drawing?
Normally, if not specified specially, the hardness requirement in the drawing means the surface hardness.
We can use "direct hardening" for "整体热处理“, and "Surface hardening" for the "表面热处理".
