Frequently Asked Questions (FAQ)
Q: What is the difference between 310 and 310S stainless steel?
A: 310S has a lower carbon content (max 0.08%) compared to standard 310 (max 0.25%), which improves weldability and reduces carbide precipitation during heat exposure.Q: Can you provide custom lengths and tolerances?
A: Yes, we offer custom lengths from 1m to 6m (or longer upon request) and tight tolerances of ±0.5mm on thickness and width. Contact us with your specific requirements.Q: What surface finishes are available?
A: We offer black (hot rolled), bright (cold drawn), pickled, and polished finishes. Custom surface treatments like mirror polishing or sandblasting are also available.Q: How do you ensure the quality of the bars?
A: We perform chemical composition analysis, mechanical testing, and dimensional inspection. Our ISO9001-certified quality management system ensures traceability and consistency.Q: What is the minimum order quantity (MOQ)?
A: For standard sizes, MOQ is typically 500 kg. For customized sizes, MOQ may vary; please inquire for details.Q: Do you provide samples before bulk order?
A: Yes, we can provide small samples (e.g., 1–2 kg) for evaluation. Sample cost is negotiable, and shipping charges apply.Q: What packaging options do you offer?
A: We offer bundling with steel straps, wooden pallets, or custom crates for export. We can also apply protective paper or plastic film to prevent surface damage.Q: How long does delivery take?
