AMS-5659 Steel, Corrosion-Resistant, Bars, Wire, Forgings, Rings, and Extrusions 15Cr - 4.5Ni - 0.30Cb (Nb) - 3.5 Cu

Technical Data Sheet. Alloy 15-5 is a precipitation hardening alloy exhibiting high strength and hardness with moderate corrosion resistance. Alloy 15-5 is a variant of the older 17-4 and 15-5 was designed to have greater toughness than S17400, especially in the through-thickness (short transverse) direction. Alloy 15-5 is used in applications ...

AMS5659/H900 Historical Issued This specification covers a corrosion-resistant steel product 12 inches (305 mm) and under in nominal diameter, thickness or, for hexagons, least distance between parallel sides, and having a maximum cross-sectional area of 144 in2 (930 cm2) in the solution and precipitation heat treated (H900) cond

AMS 5659 (UNS S15500) is a martensitic precipitation hardening stainless steel which contains 4% copper. All the same advantages of AMS 5643 (UNS S17400) are present, as well as a single low-temperature treatment. AMS 5659 ofers superior uniformity of properties with excellent traverse notch toughness and ductility.

Historical Reaffirmed AMS5659/H1025 Historical Issued This specification covers a corrosion-resistant steel product in the solution and precipitation heat treated (H1025) condition. The aged product may be supplied directly by a mill or by a producer other than the mill.

This specification covers a corrosion resistant steel in the form of bars, wire, forgings, flash welded rings, and extrusions in the solution heat treated condition (see 8.3), 12 inches (305 mm) and under in nominal diameter, thickness or for hexagons, least distance between parallel sides, and havi

GENERAL CHARACTERISTICS: 15-5 PH stainless steel is a martensitic precipitation-hardening stainless steel with approximately 15% Chromium and 5% Nickel. It has high strength, high hardness, and excellent corrosion resistance. Strength can be further increased by a single low temperature heat treatment. Compared to 17-4 …

AMS 5659 is a martensitic stainless steel that contains chromium, nickel, and copper as primary alloying elements. It also contains small amounts of phosphorus, sulfur, manganese, and carbon. The copper content in AMS 5659 enhances its corrosion resistance and precipitation-hardening properties.
