    Quality: AISI8620 Standard Performed: ASTM A29/A29M-04

    Grade:SAE8620 50CrMo4 SNCM220 805M20 4150 4140 EN24 4340


    1.Description:

    8620 is a low nickel - chromium - molybdenum medium hardenability, case hardening (carburizing) steel, generally supplied in the as rolled condition with a maximum brinell hardness of 280 (Rc30).
    Characterised by good core strength and toughness in small to medium sections with case hardness up to Rc62 when carburized, hardened and tempered.
    Pre hardened and tempered (uncarburized) 8620 can be further surface hardened by nitriding but will not respond satisfactorily to flame or induction hardening due to its low carbon content.
    8620 (carburized) is used extensively by all industry sectors for light to medium stressed components and shafts requiring high surface wear resistance with reasonable core strength and impact properties.


    2.Application: Components for the automotive and general engineering industries eg. Propeller shafts, connecting rods, gear shafts, and other automobile parts. Heavy forgings, eg. Rotors, shafts, discs.

    3.Process flow: Electric arc furnace melting→Refining furnace → Vacuum treatment furnace → Rolled →Anneal,retarded cooling,air cooling → Quenching and tempering tretment → Finishing operation → Text → Finished products
