WebWhat is HB in Hardness? The Rockwell hardness is measured using a value designated with the RB. Just like in the preceding, the RB is an assigned number for the Rockwell hardness testing value measured on the B scale. For Rockwell testing, the B scale better represents metal materials with a hardness value below HRC 20. The test is often ... Web洛氏硬度(hrc)和布氏硬度(hb)测试方法和单位都不同,两者大致为1:10的比例,hb240-270对应的洛氏硬度在hrc23~28范围。 区别:1、单位不同 洛氏硬度是以压痕塑性变形深度来确定硬度值的指标,以0.002毫米作为一个... scarface full movie free watch
