Standard Specification for Steel Bars, Alloys, for Nitriding
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This specification covers alloy steel bars, suitable for surface hardening by nitriding, designated as Classes A, B, C, and D. Class A and Class D bars are general-purpose bars; Class B bars are free-machining bars; Class C bars contain 3.50% nickel and are characterized by higher core strength. All classes are normally furnished in the hot-rolled, quenched, and tempered condition. However, centerless-ground or turned bars, in any of the classes, may be specified by the purchaser. Also, as-rolled, annealed, or unannealed bars suitable for forging may be purchased to this specification. When as-rolled, annealed, or unannealed bars are furnished, Sections 7, 11, and 12 are not applicable.
1.2 The values stated in inch-pound units are to be regarded as the standard.
