Brinell / Knoop / Vickers Hardness Testing with the CHD Master
WebCarbonitriding is usually carried out in a temperature range of 820-900°C in a gaseous atmosphere adding between 0.5 to 0.8% carbon and 0.2-0.4% (< 5%) nitrogen to the surface of plain carbon steel or low alloy steel. After diffusion time the components are directly quenched in oil. The attained case hardened depth (CHD) is usually not greater ... WebCase Depth Hardness Testing. Case depth is the thickness of the hardened layer on a specimen. Case hardening improves both the wear resistance and the fatigue strength of parts under dynamic and/or thermal stresses. Hardened steel parts are typically used in rotating applications where high wear resistance and strength is required. in the alert
