4317/X4317/17CrNiMo6/ 18CrNiMo7/ 18CrNiMo7-6

 Description:

8CrNiMo7- 6 Chrome-Nickel-Moly Carburising Steel generally supplied annealed to HB 229max. Carburised and heat treated it develops a hard wear resistant case to HRC 60-63 and a tough strong core with a typical tensile strength range of 900-1300 MPa, in small to fairly large sections.

 

APPLICATIONS:

Heavy-duty arbors, bushings, Cam Followers, wear pins, bearings, sprockets, gears and shafts, Clutch Dogs, Compressor Bolts, Extractors, Fan Shafts, Heavy Duty Gears, Pump Shafts, Sprockets, Tappets, Wear Pins, Wire Guides etc.. Or can be used for high tensile applications uncarburised but through hardened and tempered. It is used extensively by all industry sectors for components and shafts requiring high surface wear resistance, high core strength and impact properties.
