Description:
Chrome-molybdenum steel with aluminium for nitriding. After hardening the core becomes very strong – ca. 1,000 MPa resistance – and very resistant to corrosion and high temperatures. Heat & surface treatment processing enables obtaining surface hardness of more than 900 HV, which makes it well-suited for moving parts and parts exposed to friction.
Applications:
Production of structural elements of high surface hardness. For parts exposed to friction, such as cylinders, bushings, camshafts, extruders, straighteners.
