IS 25Cr13Mo6 Round Bars
Indian Standard IS 5517 (1993) 25Cr13Mo6 Round Bars is a Steel for Hardening and Tempering.
25Cr13Mo6 Round Bars is a chromium molybdenum nitriding steel characterised by its suitability for nitriding which promotes high wear resistance.
25Cr13Mo6 offers high wear resistance. The alloy also offers good shock resistance and good toughness and ductility.
After nitriding it develops a hard wear resistant case in the range of 61-65HRc with good resistance to shock and fatigue. The relatively low temperature of the nitriding process produces components with a scale free surface and minimum distortion. No significant loss of surface hardness will result from operating temperature up to 500°C.
