V361 is a 3% Cr-Mo-V nitriding low-alloy steel of premium aircraft-quality, low-alloy steel offering a tensile strength of up to over 1350MPa in the form of bars, forgings, and forging stock.
Due to the optimized production route via VIM-melting and VAR-remelting, the steel offers high impact strength and fatigue limit. It may be nitrided in the heat treated condition to obtain a wear resistant surface.
It is used typically for nitrided parts such as bearings, operating under heavy loads and high speeds at moderate temperatures, and requiring highest surface hardness, high core toughness, and less distortion than parts made from case hardening steel, but usage is not limited to such applications.
Gears, crankshafts, aircraft parts, bearing races. The alloy can be deployed for high strength non-nitrided parts of for nitride components, where high mechanical properties are required in the core.
