Organization: NPFC
Publication Date: 26 November 1990
Status: active
Page Count: 13
scope:

This specification defines the requirements of two classes of one type of steel bar, forgings and stock for forging, cobalt-free maraging, containing 18 percent nickel and capable of attaining high ultimate tensile properties by means of a relatively low temperature heat treating process.

intended Use:

Steel conforming to this specification is intended for high performance applications which require a high strength level with good fracture toughness.
