EN40B Nitriding Steel
EN40B nitriding steel stockholders and suppliers, delivering to the whole of the UK. EN40B is a chromium molybdenum steel specification 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.
