WebJan 4, 2012 · Answer: As you most likely know, carbon, and to a lesser extent manganese, have the greatest effect on hardenability in steels. Still, chromium does have an influence, which can be summarized below: “Chromium (Cr) is one of the most versatile and widely used alloying elements in steel. WebStandard ferritic steels contain 10.5 to 27 percent chromium and are nickel-free; because of their low carbon content (less than 0.2 percent), they are not hardenable by heat … WebPrecipitation-hardening stainless steels (Table 4) are chromium-nickel types, some containing other alloying ele-ments, such as copper or aluminum.

WebNitriding is a heat treating process that diffuses nitrogen into the surface of a metal to create a case-hardened surface. These processes are most commonly used on low-alloy steels. They are also used on titanium, aluminium and molybdenum.. Typical applications include gears, crankshafts, camshafts, cam followers, valve parts, extruder screws, die … WebThe carbide precipitation can be eliminated by thermal stabilization. In this method, the steel is held at 815° to 870°C (1500 to 1600°F) for several hours. Descaling: Heat treatment causes a scale to build up on the surface of the steel. The scale is removed by several methods. Pickling is done to remove scale.
