Stainless Steel Round Bars
Custom Stainless Steel Round Bars in 303, 304, 316 & More
Action Stainless supplies stainless steel round bar in a wide range of grades and sizes to support structural, machining, and fabrication applications. Round bar is a key product across construction, food processing, marine, and energy sectors, valued for its clean finish, strength, and versatility.
We offer round bar in 303, 304/304L, 316/316L, 17-4PH, and other grades. Bar is available in cold drawn, annealed, turned, or ground finishes. Standard lengths are
12′ randoms, with longer sizes available by request.
Finishes & Processing Services
Stainless round bar is typically stocked in annealed, cold drawn, smooth turned, or centerless ground finish. These options are suited for machining, forming, and shafting applications where strength and finish quality are essential. In-house services include saw cutting, large-diameter turning, chamfering, drilling, and tolerance grinding. Whether for single lengths or full production runs, our team can meet custom sizing and processing needs quickly and consistently.
