適用范圍
鋼、表面淬火鋼、銅、鋁合金、薄板、帶鋼、硬質(zhì)合金鋼、鍍鋅、鍍鉻、鍍錫、材料表面熱處理和化學(xué)表面處理的各種金屬材料。HD9-45B Motorized Superficial Rockwell & Vickers Hardness Tester with 6 steps testing force is able to meet the needs of superficial Rockwell & Vickers hardness tests. Testing force can be loaded, kept and unloaded automatically. Therefore the tester is easy to use and widely welcomed by many users. (The present instrument can be reformed specially to measure Brinell hardness value for aluminum products according to user's special requirement.)Usage Range:
Steel, surface hardened steel, copper, aluminum alloy thin sheet, hard alloy steel, zinc layers, chrome layers, tin layers, surface heat treating and chemical treating materials, etc.技術(shù)數(shù)據(jù)（Technical Specifications）
