DMS 1565 - 431 Stainless Steel
DMS 1565 is a specification by McDonnell Douglas/Boeing for 431 Stainless Steel, which is classified as a corrosion-resistant special aircraft quality material. Even though new specifications have been developed to replace this one, Fighter Jet Metals can still offer this material according to the standards set by the DMS 1565 specification, providing quality aircraft-grade stainless steel materials.
Applications of DMS 1565
- Aircraft fasteners, fittings, and structural members
- Marine and offshore structural components
- High-strength bolts, shafts, and valves
- Components requiring both toughness and corrosion resistance
What is 431 Stainless Steel ?
431 Stainless Steel is a high-strength martensitic steel with the highest corrosion resistance of all martensitic stainless steel grades. It is intended for extreme structural and marine applications, with high toughness, high tensile strength, and moderate corrosion resistance, making it the top choice for use in aircraft and high-performance industrial products.
