PACIFIC 86L20 is cold drawn in the as rolled condition. The addition of lead gives free machining characteristics to this carburizing grade of alloy steel. Heat treatment is carried out just as it would be for the standard grade to achieve similar results for hardness and case depth. Even though 86L20 is considered a carburizing grade, it sometimes is used in the as received (natural) condition.
