　　晶泰钢材专业销售--- EN40B EN40铬钼钢EN40B is a chromium-molybdenum nitriding steel usually supplied in the hardened and tempered condition, which offers high wear resistance together with good toughness and ductility. It is characterised by its suitability for nitriding, which can give a hard wear resistant core in the range of 61-65Rc. The relatively low temperature of the nitriding process produces components with a scale free surface, and minimum distortion
