Depth hardness
WebVery hard indenters of defined geometries and sizes are continuously pressed into the material under a particular force. Deformation parameters, such as the indentation depth in the Rockwell method, are recorded to give measures of hardness. Common indentation hardness scales are Brinell, Rockwell and Vickers.

WebOct 17, 2024 · Typical nitrided case depths for steel are 0.010-0.020 inches (0.25-0.50 mm). Shallower or deeper case depths are possible. Significantly longer cycles are required for case depths about 0.020 inch due to the slow diffusion rate of nitrogen into steel. Stainless and tool steel case depths are typically limited to 0.001-0. 003 inch (0.025-0.075 mm). WebCase depth refers to the thickness of a material’s hardened layer.
