Abstract

Form This specification covers a nitriding grade of premium aircraft-quality, low-alloy steel in the form of bars, forgings, mechanical tubing, and forging stock. AMS6496 and AMS6498 cover UNS K23280 with other quality levels. Application These products have been used typically for nitrided parts such as bearings, operating under heavy loads and high speeds at moderate temperatures, and subject to very rigid inspection standards, and requiring highest surface hardness, high core toughness, and less distortion than parts made from steel requiring quenching to case harden, but usage is not limited to such applications. Classification Steel covered by this specification is classified by melting practice as follows: Type 1 Electroslag remelted (ESR) Type 2 Consumable electrode vacuum remelted (VAR) Unless a specific type is ordered, either type may be supplied.
