Web26 Jan 2024 · The hardness was tested using the WM, BM, and HAZ areas of the weld samples cooled using air, water, and ice. The Rockwell hardness values distribution for the A36 steel plate cooled with air is presented in Figure 14 and the maximum value of 86.9 HRB was found in the WM while the minimum, 75.2 HRB, was in the HAZ. This means the … WebThe Brinell hardness testing method is similar to the above Rockwell testing method with a couple differences. A typical test on steel uses a 10mm diameter steel (or tungsten) ball with 3,000kg of force. A steel ball is used for most materials; the tungsten ball is used primarily for harder materials like tool steel. teyr star wars
