Product Code:SAE AMS5726
Title:Steel, Corrosion and Heat-Resistant, Bars and Wire, 15Cr - 25.5Ni - 1.2Mo - 2.1Ti - 0.006B - 0.30V, 1800 °F (982 °C) Solution Heat Treated and Work-Strengthened Consumable Electrode Remelted 200 ksi (1379 MPa) Tensile Strength Capability
Issuing Committee:Ams F Corrosion Heat Resistant Alloys Committee
Scope:This specification covers a corrosion and heat-resistant steel in the form of work-strengthened bars and wire 1-1/4 inches (31.8 mm) and under in nominal diameter or least distance between parallel sides. These products have been used typically for parts, such as fasteners, requiring room-temperature minimum tensile strength of 200 ksi (1379 MPa) after precipitation heat treatment for use up to 1000 °F (538 °C) and having oxidation resistance up to 1200 °F (649 °C), but usage is not limited to such applications.
