Frequently Asked Questions
304 stainless steel contains 18% chromium and 8% nickel, offering good corrosion resistance in most environments. 316 stainless steel contains an additional 2-3% molybdenum, which enhances its resistance to pitting corrosion, particularly in chloride environments like seawater. 304 is more cost-effective for general applications, while 316 is preferred for marine or highly corrosive environments.
We offer several standard surface finishes including 2B (bright annealed and cold rolled), BA (bright annealed), NO.1 (hot rolled), and HL (heat colored). We can also provide custom finishes to meet specific customer requirements.
For standard specifications, our lead time is typically 7-14 days. Custom orders may require additional time depending on the specific requirements. We recommend contacting our sales team for accurate lead time estimates based on your specific order details.
Yes, we provide material test reports (MTRs) with all our shipments. These reports verify the chemical composition, mechanical properties, and other quality parameters of the material. We can also provide additional testing and certification as required by our customers.
