EN40B Nitriding Steel
EN40B steel stockholders and suppliers. EN40B is a chromium molybdenum steel specification available as full bar lengths or cut pieces with delivery to the whole of the UK. It is usually supplied in the hardened and tempered ‘T’ condition, which offers high wear resistance together with good toughness and ductility. EN40B in T condition has a tensile of 850-1000 N/mm². It is characterised by its suitability for nitriding, which can give a hard wear resistant case in the range of 61-65Rc. The relatively low temperature of the nitriding process produces EN40B components with a scale free surface, with minimum distortion during the heat treatment process. EN40B may be used in its supply condition (usually ‘T’) for applications and components which require a high tensile steel strength and high creep strength at temperatures up to 600°C.
