Frequently Asked Questions (FAQ)
What is 304 Stainless Steel Round Bar?

304 Stainless Steel Round Bar is an austenitic stainless steel bar with excellent corrosion resistance, weldability, and machinability. It is widely used in machinery, construction, food processing, and industrial manufacturing.

What is the difference between bright, ground, and polished stainless steel rods?
  • Bright Rod: Cold drawn with a smooth finish and precise dimensions.
  • Ground Rod: Precision ground for tighter tolerances and superior roundness.
  • Polished Rod: Mechanically polished to achieve a decorative or mirror-like surface.
What standards do your products meet?

Our products comply with ASTM A276, ASTM A479, EN 10088, and JIS G4303, and are supplied with EN 10204 3.1 Mill Test Certificates upon request.

Do you offer custom machining services?

Yes. We provide cutting, CNC turning, milling, drilling, threading, grinding, polishing, and other custom processing services based on customer drawings.
