Type 301 Stainless Sheet

Supplied to AMS 5517, 5518, 5519 & 5901

We supply 301 stainless sheet to specifications including AMS 5517.

301 stainless steel is one of the most common of the 300 series austenitic steels. It is widely used in aircraft in sheet form and comes in four main conditions and specifications, which offer different strengths according to your requirements.

301 stainless steel sheet is a versatile material which varies in mechanical performance dependent on the chosen delivery condition. The alloy may be manipulated to deliver different performance qualities dependent on customer requirements.

About Type 301 Stainless

The alloy offers numerous benefits, including good resistance to atmospheric corrosion. However, the alloy is susceptible to carbide precipitation in the welding zone which may restrict the alloy's suitability for specific applications. Our 301 sheets also benefit from high strength and good weldability, and the finished product affords a pleasing aesthetic appearance. Material ductility is also good after cold working, although cold working removes the alloy's non-magnetic characteristics. Corrosion-resistant performance is at its best in the cold worked and annealed state.

Aerospace Industry Applications

Type 301 stainless steel sheet finds extensive use in the aerospace and MRO sectors with engineering applications, including structural parts, instrumentation panels, cabin interiors and aesthetic trims.

Delivery Conditions

The conditions are achieved by cold working the metal and include Condition A (Annealed) (AMS 5901), quarter hard (AMS 5517), half hard (AMS 5518) and hard (AMS 5519). Smiths MRO offers all of these conditions in stock according to the AMS specifications, such as AMS 5517 or AMS 5518. Our stock ranges include incremental thicknesses from 0.016" to 0.100".
