SAE 8620 Steel

SAE 8620 steel is low nickel-chromium-molybdenum steel. It is a case hardening carburizing alloy steel too. This alloy steel is flexible during hardening treatments, thus enabling improvement of case/core properties. It is usually supplied in as-rolled condition and bright bar form. We can provide rounds from 23.5mm to 80mm for SAE 8620.
