This specification covers a corrosion-resistant steel in the form of welding wire. Primarily for use as filler metal for gas-tungsten-arc and gas-metal-arc welding of low-alloy steels where response to heat treatment is required in the weld.
This specification covers a corrosion and heat resistant nickel alloy in the form of bars, forgings, flash welded rings, and stock for forging, flash welded rings, or heading. These products have been used typically for parts, such as bolts and turbine blades, requiring high strength up to 1500 degrees F (816 degrees C) and oxidation resistance up to 1750 degrees F (954 degrees C), but usage is not limited to such applications.
This specification covers an aluminum alloy in the form of die forgings, hand forgings, rolled rings, and stock for forgings on rolled rings. Primarily for applications, such as aircraft structural members, requiring material with moderately high strength. Certain design and processing procedures may cause these forgings to become susceptible to stress corrosion cracking; ARP 823 recommends practices to minimize such conditions.
SUPERSEDING SPECIFICATION: The requirements of this specification are embodied in the latest issue of AMS 4149, ALUMINUM ALLOY FORGINGS, 5.6Zn - 2.5Mg - 1.6Cu - 0.23Cr (7175-T736), Solution and Precipitation Heat Treated. The requirements of the latest issue of AMS 4149 shall be fulfilled whenever reference is mad to this specification.
This specification covers honeycomb core made of polymide paper sheets and supplied in the form of blocks, slices, and ordered shapes, the cells of the core being in an overexpanded, rectangular configuration. This honeycomb core has been used typically for bonded sandwich structures requiring high strength and corrosion resistance in the temperature range -67 to +180 degrees C (-55 to +82 degrees F), for use in single curvature parts, but usage is not limited to such applications.
