What is 17-4 Annealed Stainless Steel?

Trinity Brand Industries is one of the top 17-4 stainless steel suppliers of shim stock, helping customers take advantage of this durable and dependable material. Also commonly referred to as 17-4 PH, this is a precipitation hardening type of stainless steel in the solution annealed state known as Condition A. This means it provides strong corrosion resistance and machinability before it is age hardened. The heat treating process is used typically after forming to help the metal achieve higher strength without losing its stainless performance.

17-4 stainless steel is alloyed with about 17% chromium, along with about 3% to 5% each of nickel and copper. There also are trace amounts of carbon, phosphorous, and sulphur.

Available Formats

Trinity Brand Industries has a selection of sheets, rolls, and strips for shim stock in this material. Our inventory contains a variety of common thicknesses, tolerances, and standard widths. We also provide multiple finish options, and can cut stock to size when requested. All stock is fully traceable with MTRs, as well.

Applications Where 17-4 Annealed Excels

In most cases, engineers start at Condition A for forming, then apply heat treatments to harden 17-4 stainless steel to reach targets such as H900 or H1025 to lock in added strength depending on the application. This alloy is typically used for applications including:

• Aerospace hardware
• Pump shafts
• Valves and fasteners
• Food processing components
• Medical and marine instrumentation
• Precision tooling
