Frequently Asked Questions (FAQ)
❓ What are the main differences between 304 and 316 stainless steel?
304 is the standard universal grade for general use, while 316 contains molybdenum, which provides superior resistance to pitting and corrosion in chloride-heavy or marine environments.
❓ Can I request custom slitting for specific widths?
Yes, custom slitting services are available with a minimum width of 22mm to meet your specific project requirements.
❓ What types of surface finishes do you provide?
We offer a wide range of finishes including 2B, BA, No.4 brushed, Hairline (HL), Mirror, PVD Coating (Gold, Rose Gold, Black), and Etched patterns.
❓ Are Mill Test Certificates (MTC) provided?
Yes, Mill Test Certificates (MTC) per EN 10204 3.1 are provided for every shipment to guarantee chemical composition and mechanical properties.
❓ How is the material protected during international shipping?
We use ISPM 15 compliant pallets, industrial PE stretch film, waterproof paper, and steel edge protectors to ensure seaworthy protection.
❓ Do you offer titanium-stabilized grades for high-temperature use?
Yes, Grade 321 is available, which is titanium-stabilized to prevent chromium carbide formation during welding or high-temperature service.
