High-performance 317/317L stainless steel bars from a leading Chinese manufacturer. Superior corrosion resistance, formability, and strength for marine, chemical, and food-grade applications.
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.

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.
We are a top manufacturer of 309 stainless steel bars, offering excellent heat resistance, high strength, and corrosion protection. Custom sizes and finishes available with global delivery.
Discover top-grade 304L stainless steel bars with excellent weldability and corrosion resistance. Ideal for structural, fabrication, and chemical processing applications. OEM available.
High-quality 304 stainless steel bar with excellent corrosion resistance and formability. Chinese manufacturer offering round, square, and flat bars with OEM/ODM customization.
Looking for a trusted 201 stainless steel bar manufacturer? We offer corrosion-resistant, high-strength 201 stainless steel bars in custom sizes for various industrial uses.
The added molybdenum in 317 provides greater resistance to pitting and crevice corrosion, making it ideal for chemical and marine applications.
Yes. 317L has lower carbon content, which minimizes carbide precipitation during welding and maintains corrosion resistance in welded areas.
While round bars are standard, we can also supply square, hexagonal, or custom-shaped bars based on your specifications.
Our 317/317L stainless bars meet ASTM A276, ASTM A479, and EN/GB standards, with full traceability and MTC support.
It’s widely used in food and beverage equipment, marine components, architectural structurese chemical process plants.
