洛氏硬度標準塊產品介紹

洛氏硬度的測試方法是用一個120度的金剛石圓錐體或直徑為1.59mm/3.18mm的鋼球,在一定載荷下壓入被測材料表面,有壓痕深度來求出材料的硬度值。


HRA 試驗力為588.4N(60kg) HRA 20-88, 用于測定硬度超過70HRC的金屬(如碳化鎢,硬質合金等), 也可測定硬的薄板材料以及表面淬硬的材料。

HRB試驗力980.7N(100kg) HRB 20-100,用于測定較軟的或中等硬度的金屬以及未經淬硬的鋼制品。

HRC試驗力為1471N(150kg) HRC 20-70,用于測定經過熱處理的鋼制品硬度。


實踐證明,金屬材料的各種硬度值之間,硬度值與強度值之間具有近似的相應關系。因為硬度值是由起始塑性變形抗力和繼續塑性變形抗力決定的,材料的強度越高,塑性變形抗力越高,硬度值也就越高。但各種材料的換算關系并不一致。


Euro products硬度標準塊上均刻有序列號,可保證其國際標準的追溯性。

硬度標準塊均采用優質材料制成,可保證硬度值的可靠性和穩定性。
