Stainless steels are a group of steels that contain at least 10.5% chromium. The addition of this 
element, along with a wide variety of others, generally improves corrosion resistance and mechanical properties at high temperatures making them suitable for a range of arduous applications.
Aerospace stainless steel bar is stocked in a range of both metric and imperial sizes selected to best match current aircraft build programs. Bars can be supplied to many different end-user approvals either in full lengths or billeted to a size ready for machining operations.
We specialize in 17-4, 17-7, 15-5, 321, 304, and 21-6-9, but carry a great selection of stainless steel aircraft bar such as 13-8, 303, 316, 347, 410 and 431 in a variety of additional specifications. We also offer cut to length to suit your requirements.
