- 201 is ideal for budget-sensitive projects with moderate corrosion requirements.
- 304 is the industry-standard choice, offering the best overall balance of corrosion resistance, strength, and cost.
- 316L is the premium option for highly corrosive, marine, chemical, and high-hygiene applications where maximum durability is essential.
Our 304, 201, and 316L stainless steel round bars are widely used in a variety of industrial applications thanks to their excellent corrosion resistance, high strength, and precision machining performance.
Our precision ground stainless steel round bars are available in customized sizes and are widely exported for industrial, commercial, and engineering projects worldwide.
The main differences are corrosion resistance, nickel content, and application:
- 201: Cost-effective, good strength, suitable for indoor and general industrial use.
- 304: Excellent corrosion resistance and versatility, ideal for food processing, construction, and machinery.
- 316L: Superior resistance to chlorides, acids, and seawater, making it ideal for marine, chemical, pharmaceutical, and medical industries.
Yes. We provide precision ground stainless steel rods with excellent dimensional accuracy, smooth surface finish, and tight tolerances. These are ideal for CNC machining, precision components, shafts, and industrial equipment.
For highly corrosive or marine environments, 316L stainless steel is the preferred choice because its molybdenum content provides outstanding resistance to pitting, crevice corrosion, and chloride attack. For general applications, 304 stainless steel offers an excellent balance of performance and cost.
We offer multiple surface finishes, including:
- Hot Rolled
- Cold Drawn
- Bright
- Precision Ground
- Peeled
- Polished (180G, 240G, 320G, 400G, Mirror Finish)
Custom finishes are also available upon request.
