Hardness is the ability of steel to resist indentation and abrasion. The two most common hardness tests are Brinell and Rockwell. In the Brinell test, a small hardened steel ball is forced into the steel by a standard load, and the diameter of the resulting impression is measured. The Rockwell test measures the depth of the indentation.
Measures of water hardness. Hardness is caused by compounds of calcium and magnesium, and by a variety of other metals. General guidelines for classification of waters are: 0 to 60 mg/L (milligrams per liter) as calcium carbonate is classified as soft; 61 to 120 mg/L as moderately hard; 121 to 180 mg/L as hard; and more than 180 mg/L as very hard.Guide to Physical Weld Testing - Weld GuruDec 12, 2019 · A hardness test is used to determine the hardness of weld metal.
