Versatile, corrosion-resistant stainless steel ideal for
structural, industrial, and fabrication applications. Available
in angles, bars, channels, flats, and beams.

The aerospace industry operates under some of the most exacting material requirements of any sector. Components must perform reliably across extreme temperature cycles, withstand significant mechanical stress, and meet strict weight-to-strength ratios, all while adhering to rigorous quality standards such as AMS, ASTM, and MIL specifications.

Stainless Shapes works directly with aerospace engineers, procurement teams, and fabricators to source the right stainless steel, titanium, and nickel-based alloy for every application. Whether you are specifying material for a new airframe structure, replacing components on ground support equipment, or sourcing for an MRO project, our team combines deep metallurgical knowledge with a broad stock range to keep your program on track.

In aerospace, an incorrect material specification can have cascading consequences, from failed NDT inspections and re-certification costs to safety risks and program delays. The choice between a standard austenitic stainless grade and a precipitation-hardened alloy, or between commercially pure titanium and a Ti-6Al-4V structural alloy, fundamentally changes a component’s behavior under load, temperature, and corrosive exposure.

Our specialists understand these trade-offs and can help you navigate grade selection, form availability, and certification requirements before you commit to a specification.

• Airframe Structures: Stainless and titanium alloys for primary and secondary structural members, frames, ribs, and bulkheads requiring high strength and corrosion resistance.
• Jet Engine Components: Nickel superalloys and titanium for turbine casings, compressor blades, exhaust nozzles, and combustor hardware operating at extreme temperatures.
• Fasteners and Fittings: 17-4 PH, 15-5 PH, and A286 stainless for high-strength fasteners, bolts, and structural fittings requiring consistent mechanical properties.
• Hydraulic and Fluid Systems: 316/316L tube, pipe, and fittings for hydraulic actuation systems, fuel lines, and pneumatic ducting where cleanliness and corrosion resistance are critical.
• Landing Gear: High-strength stainless and titanium bar for landing gear components requiring outstanding fatigue performance and resistance to hydraulic fluid environments.
• Ground Support Equipment: Structural stainless sections, including angles, channels, and beams, for MHE, test fixtures, maintenance platforms, and tooling exposed to outdoor and industrial conditions.

• Material Test Reports (MTRs): Full traceability documentation is available for all aerospace-grade materials, supporting your quality management and compliance requirements.
• Specification Knowledge: Our team is fluent in AMS, ASTM, and ASME specifications, helping you match grades to the correct certification standard for your application.
• Broad Grade and Form Inventory: We stock stainless, titanium, and nickel alloys across structural sections, bars, plates, and tubes from a single source, reducing lead-time complexity.
• Expert Material Consultation: From grade substitution questions to understanding the implications of heat treatment conditions, our specialists provide substantive technical support.
• Responsive Quoting: Aerospace programs move on tight schedules. Our team provides fast, accurate quotes to support your procurement timelines.

What is the difference between the 17-4 PH H900 and H1025 conditions?

17-4 PH stainless steel is supplied in different age-hardened conditions designated H900, H925, H1025, H1075, and H1150, each corresponding to an aging temperature in degrees Fahrenheit. H900 provides the highest strength and hardness but lower toughness. H1025 and above trade some strength for improved ductility and fracture toughness. The correct condition depends on your specific strength and toughness requirements. Our team can help you select the appropriate option.

Can you supply titanium with AMS certifications?

Yes. We supply titanium, including Ti-6Al-4V (Grade 5) and commercially pure grades, with full material test reports documenting conformance to AMS specifications such as AMS 4928 for Ti-6Al-4V bar. Please specify your required specifications when requesting a quote.

What nickel alloys do you stock for high-temperature aerospace applications?

Stainless Shapes stocks a broad range of nickel-based alloys and precipitation-hardened stainless steels for aerospace programs. Our nickel alloy inventory includes Nickel 200, Monel 400, Monel K500, Inconel 600, Inconel 718 and 718 Aged, Alloy C22, Hastelloy C276, Hastelloy X, L605, and Haynes 242, covering applications from corrosion-resistant fluid system components through to high-temperature engine hot sections and combustor hardware. We also stock 13-8 PH, 15-5 PH, and 17-4 PH precipitation-hardened stainless steel, all available in multiple age-hardened conditions, including H900, H925, H1025, H1075, and H1150 to suit your specific strength, toughness, and hardness requirements. 

Do you supply to defense aerospace programs?

Yes. We work with engineers and procurement professionals across both commercial aviation and defense aerospace programs. Our team understands the traceability and documentation standards associated with defense material sourcing and can support your requirements accordingly.
