Webster Model B-75 for Mild Steel & Brass
Webster Model B-75 for Mild Steel & Brass Hardness tester Webster for Mild Steel & Brass (Standard Capacity up to ¼") Model B-75 Tester was developed to obtain a more sensitive response to slight changes in the upper range of hardness covered by Model B. This sensitivity is particularly useful in testing mild steel and stronger aluminum alloys. For brass, the B-75 covers the range from annealed to full-hard. This added sensitivity is accomplished by incorporating a penetrator of a slightly different contour and a heavier load spring than used in Model B. The 20 graduations on the Webster dial indicator cover the range between 20 and 100 on the Rockwell B scale. Each tester is shipped in a fitted case with a spare penetrator, adjusting wrench, and standard test strip. Delivery may take up to approx. 4-6 weeks depending on stock availability.
