118-2020-2 Rockwell Hardness (C & B Scales) Price: $490.00


Participants receive during each test cycle two steel test blocks with slightly different hardness numbers. Each block is pre-tested for homogeneity. No sample preparation required. ASTM Test Method E18 is referenced.
 
For this test the Rockwell C scale is used in May, while the B scale is used in August; the test is designed for laboratories that want to test both scales one time each year. Laboratories preferring to test C and B scales two times per year should see CTS Tests 119 and 120.
