Product Description

AISI 8620 Cold Drawn Bright Steel Round Bar / Cold Drawn Steel 8620
AISI 8620 alloy steel is a common, carburizing alloy steel. This alloy steel is flexible during hardening treatments, thus enabling improvement of case/core properties. The following datasheet will provide more details about AISI 8620 alloy steel.
