The Portable Steel Hardness Tester measures the hardness of metals in the range of 20 to 65 HRC on the equivalent Rockwell C Scale. The test measures the hardness by pressing an indentor into the surface of the steel with a specific load and them measuring how far the indentor was able to penetrate. HARDNESS VICKENS HARD. The Brinell hardness test is the method measuring hardness through measuring the diameter of the indentation left by an indenter or other materials of a specified diameter, under a certain load into the surface. Rockwell hardness number can be represented by HRB. between HRB, BH, HV and Rm, refer to iron-foundry.com. 15T Scale, 15 Kgf (15T) Rockwell Superficial Hardness No. HRC - diamond Pump Shell and Valve Body HBS indicates that the indenter is a hardened steel ball, which is used to determine … SITEMAP Approximate Hardness Conversion No.s for.
