Abstract

This specification covers the standard requirements for UNS N08020, UNS N08026, and UNS N08024 alloy plate (hot- or cold-rolled), sheet, and strip. The alloys shall be furnished and heat treated at certain annealing condition and temperature range: stabilized annealing for UNS N08020 alloy; solution annealing for UNS N08026 alloy; and annealing for UNS N08024 alloy. The materials shall conform to the specified chemical composition requirements for carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, molybdenum, copper, columbium, tantalum, nitrogen, and iron. Tensile strength, yield strength, elongation, and Brinell or Rockwell hardness of the alloys shall also meet the specified mechanical property requirements.
