Introducing the hardness conversion formula and table for Rockwell Hardness (HRC, HRB) to Brinell Hardness (HB or BHN) by Dandong Foundry in China.
Rockwell c scale (HRC):Used for measuring the hardness of hard materials, such as steel and hard alloys. The indenter is a diamond cone. Rockwell b scale (HRB):Suitable for softer materials like aluminum, brass, and softer steels. The indenter is a hardened steel ball. Rockwell a scale (...
Rockwell hardness number of 80 on the Rockwell B scale. Similarly, 81 HR 30N indicates a Rockwell hardness number of 81 on the Rockwell 30N scale. Rockwellhardness testsare used for determining the hardness of most metals and alloys, ranging from the softestbearing materialsto the hardest ...
最常见的是洛克韦氏硬度 B (HRB), 它使用 1/16 in. 硬化钢球压连同100公斤重量, 和洛克韦氏硬度 C (人权委员会), 它使用一个钻石锥压和150公斤重量。HRB 测试是为低范围硬度的材料, 如铝, 黄铜和软钢, 而人权委员会的测试是用于高硬度的材料, 如硬钢。更小的重量 (15 到45公斤) 用于洛克韦尔表面硬度...
gets measured and recorded. Then, the testing technician deducts the light penetration value (A) from the deep penetration measurement (B). The numeric value of B minus A then gets transferred to the Rockwell C scale, and its corresponding value becomes the metal’s Rockwell hardness indicator...
