Frequently Asked Questions
1. What sizes are available for your 304 ss hex bar?
We supply standard sizes from 7 mm to 100 mm across flats (AF). Custom dimensions can also be manufactured upon request.
2. What is the difference between cold-drawn and hot-rolled hex bars?
Cold-drawn hex bars provide tighter dimensional tolerances, smoother surfaces, higher strength, and better straightness, making them ideal for precision machining.
3. Is 304 stainless steel suitable for machining fasteners?
Yes. 304 stainless steel offers excellent machinability, corrosion resistance, and strength, making it one of the most commonly used materials for bolts, nuts, threaded rods, and precision fasteners.
4. Can you provide custom lengths?
Yes. We offer standard lengths of 1–6 meters as well as precision cut-to-length services according to customer drawings.
5. Which international standards do your products comply with?
Our hexagonal bars comply with ASTM A276, ASTM A479, EN 10088, and JIS G4303 standards.
6. Do you provide Material Test Certificates (MTC)?
Yes. We can provide EN10204 3.1 Material Test Certificates, chemical analysis reports, and mechanical property test reports with each shipment.
7. Is 304 stainless steel magnetic?
In the annealed condition, 304 stainless steel is generally non-magnetic. However, slight magnetism may develop after cold working.
8. What industries commonly use stainless steel hexagonal bar?
They are widely used in machinery manufacturing, automotive, construction, food processing, chemical equipment, marine hardware, and precision engineering.
