Global Leader in Stainless Steel Rod and Round Bar Fabrication
Daxun is a trusted global supplier and exporter of SS 17-4PH/630 round bars and rods. We produce high-quality products in a range of surface finishes, end treatments, dimensions, shapes, and sizes to suit your exact requirements.
Why Choose SS 17-4PH?
SS 17-4PH is a martensitic stainless steel that undergoes precipitation hardening for superior mechanical properties. Its alloying elements—nickel, copper, and chromium—contribute to excellent strength, corrosion resistance, and durability. Widely adopted in the aerospace industry, this alloy is ideal for fasteners and other structural components thanks to its refined microstructure, which is developed through a controlled remelting process.
Optimized Properties Through Heat Treatment
UNS S17400, the designation for 17-4PH, responds well to heat treatment and aging. These processes enhance its toughness and ductility, making it suitable for demanding applications. Compared to many high-nickel, non-ferrous alloys, 17-4PH provides a more cost-effective solution without sacrificing performance.
A Versatile Choice for Many Industries
Stainless steel 17-4PH round bars are popular in manufacturing and engineering due to their corrosion resistance, high strength, and ease of production. The “PH” stands for precipitation hardening, a treatment method that further improves the material’s mechanical properties. With its balanced combination of features and value, 17-4PH is an excellent choice for a wide range of industrial projects.
ur network of service centers stock stainless steel bar products for fast, ready supply of bar in common sizes and alloys.We also produce custom-sized stainless steel rods and can arrange inventory schedules for quick turnaround in a timely manner if quantities are below factory minimums.Daxun Alloys stocks stainless steel round bars with diameters ranging from 1/16″ to 26″. Round bars are available in nearly every grade of stainless steel, including 302, 303, 304/L, 309/S, 310/S, 316/L, 317/L, 321, 321/H, 347, 347H, 410, 416, 420, 440C, 17-4PH, Duplex 2205, and Alloy 20. Heat treated stainless steel round bars are offered in 17-4PH, H900 temper (on request), H1025, H1150, Double H1150, and H1150M. Other heat-treated tempers can be manufactured upon request. We stock the following 400 series stainless steels: 410, 430, and 416. We also carry 303, 304, and 316/L precision and bearing quality stainless steel round bars. The majority of our inventory consists of our unique machined bar grades: stainless steel round bars that are melted to consistent standards to increase machinability and lower total cost per component. Our stainless steel bar processing machinery allows Daxun Alloys to produce to our customers’ exact specifications.
It performs reliably in high temperature service conditions between 600°F and 800°F.
