The working vacuum should be selected according to the material and heating temperature. First, the working vacuum required for no oxidation heating should be met, and then the surface brightness, degassing and evaporation of alloy elements should be comprehensively considered. The working vacuum of commonly used materials is recommended as follows:
真空熱處理 Vacuum heat treatment | 推薦工作真空度Recommended working vacuum | 真空釬焊 Vacuum brazing | 推薦工作真空度 Recommended working vacuum |
鋼合金工具鋼、結(jié)構(gòu)鋼、軸承鋼 Steel (alloy tool steel, structural steel, bearing steel) | 1-10-1Pa | 鋁制產(chǎn)品 Aluminum products | 10-3Pa |
含Cr、Ni、Si等合金鋼 Alloy steel containing Cr, Ni, Si, etc | 10Pa | 銅基產(chǎn)品 Copper base products | 10-1-10-2Pa |
不銹鋼，高溫合金，鐵基、鎳基、鈷基 Stainless steel, high-temperature alloy, iron, nickel, cobalt base | 10-2-10-3Pa | 鎳基產(chǎn)品Nickel-based products | 10-2-10-3Pa |
鈦合金 Titanium alloy | 10-3Pa | 多元合金產(chǎn)品Multicomponent alloy product | 10-1-10-3Pa |
銅合金 Copper alloy | 133-13.3Pa | 高速鋼回火 High speed steel Tempering | 1.3-10-2 |
