317 Stainless Steel Bar Supplier | China’s Trusted Stainless Steel Bar Manufacturer

China’s Trusted Stainless Steel Bar Manufacturer

The 317 stainless steel bar is a molybdenum-bearing austenitic alloy with significantly enhanced resistance to pitting, crevice corrosion, and chemical attack—especially in acidic, chloride-rich, and marine environments. Thanks to its 3–4% molybdenum content, the 317 and 317L grades outperform conventional 304/304L bars in both corrosion performance and durability.

Our factory delivers precision-finished 317 stainless steel round bars with consistent quality, reliable dimensional accuracy, and customizable lengths and finishes. As China’s trusted stainless steel bar manufacturer, we serve global industrial clients in pharmaceuticals, food processing, marine fabrication, and architectural construction, offering complete support for OEM and project-based orders.

Possible styles

317 stainless steel bars are predominantly manufactured in round bar form, suitable for machining and fabrication in high-corrosion-risk sectors. Our facility also supports processing into square bars, hex bars, or custom profiles depending on your project requirements. All bar styles are available in cold drawn, hot rolled, or ground finishes, and we offer bright, black, or pickled surfaces upon request.
