This specification covers the requirements for producing a continuous white layer with controlled extent of porosity by means of a gaseous process, automatically controlled to maintain set values of the nitriding and carburizing potentials that determine properties of the nitrocarburized surface. Automatic control is intended to ensure repeatability of nitrogen and carbon content of the white layer which influences properties such as wear and corrosion resistance, ductility and fatigue strength.
This specification covers a corrosion and heat-resistant nickel alloy in the form of bars, forgings, and flash welded rings up to 4.00 inches, including (101.6 mm, including) in nominal diameter or least distance between parallel sides, and stock of any size for forging or flash welded rings (see 8.5).
This specification covers a titanium alloy in the form of bars, wire, forgings, and flash welded rings 4.000 inches (101.60 mm) and under in nominal diameter or least distance between parallel sides and of stock of any size for forging and flash welded rings.
This specification covers a titanium alloy in the form of bars, wire, forgings, flash welded rings up through 4.000 inches (101.60 mm) in diameter or least distance between parallel sides and stock of any size for forging, heading, or flash welded rings (see 8.6).
This specification covers the general requirements for aluminum and aluminum alloy plate and sheet. Specific requirements for plate and sheet of a particular alloy are covered by the applicable detail specification (See 6.3).
This document specifies the procedure and requirements for gas nitriding low-alloy and tool steels by the use of raw or dissociated ammonia. Additional alloys and steel families (e.g., stainless steels) can also be nitrided using parameters acceptable to the cognizant engineering organization.
