Frequently Asked Questions (FAQ)
Q: What is the corrosion resistance of 304 Stainless Steel Round Bar?
A: Containing 18-20% Chromium and 8-11% Nickel, 304 stainless steel forms a dense chromium oxide passive layer, providing good resistance to most oxidizing acids and atmospheric corrosion.
Q: How to choose between Bright and Black surface finishes?
A: Bright finish offers a smooth, aesthetic surface suitable for direct-use decorative and precision parts. Black finish, with its oxide layer, is ideal for industrial applications requiring further processing or where surface appearance is less critical.
Q: Do you provide custom sizes outside standard specifications?
A: Yes, we support customization of diameter, length, and tolerance. Please consult our sales team for minimum order quantities (MOQ).
Q: What is the lead time after order confirmation?
A: Standard specification products are typically in stock and can be dispatched within 3-5 working days. Custom products require a production lead time of 15-30 days, depending on order volume.
Q: Are your products compliant with international standards?
A: Our products comply with various international standards, including Chinese GB, American ASTM, Japanese JIS, German DIN, and European EN standards. Relevant certifications can be provided.
