AISI 8620 Steel is a low alloy nickel, chromium, molybdenum case hardening steel, generally supplied in the as rolled condition with a maximum hardness max HB 255. It is commonly supplied in 8620 round bar.

It is flexible during hardening treatments, thus enabling improvement of case/core properties. Pre hardened and tempered (uncarburized) 8620 can be further surface hardened by nitriding. However, it will not respond satisfactorily to flame or induction hardening due to its low carbon content.

Steel 8620 is suited for applications which require a combination of toughness and wear resistance.

We supplies AISI 8620 round bar in hot rolled / Q+T / normalized condition. Available diameter from 20mm to 300mm for immediate shipment.
