Frequently Asked Questions
1. What are the most common applications for 304L stainless steel? 304L is widely used in chemical containers, welded structures, and components where post-weld heat treatment isn't possible, due to its low carbon content which minimizes carbide precipitation.
2. How does 316 differ from 304 stainless steel? 316 contains 2-3% molybdenum, which provides significantly better resistance to pitting and crevice corrosion in chloride-rich environments like marine settings compared to 304.
3. What surface finishes are available for decorative projects? We offer BA (Bright Annealed), Mirror, No.4 Brush, Hairline (HL), as well as specialty finishes like PVD coating (Gold, Rose Gold, Black), etching, and embossing.
4. Can I request custom widths for the steel sheets? Yes, we provide custom slitting services. While standard widths include 1000mm, 1219mm, and 1500mm, we can slit down to a minimum of 22mm.
5. Are Mill Test Certificates (MTC) provided? Yes, all shipments include a Mill Test Certificate (MTC) per EN 10204 3.1, guaranteeing chemical composition and mechanical properties.
6. How do you ensure the material stays flat during shipping? We use tension leveling systems during processing and secure the sheets between plywood boards with steel edge protectors and strapping on fumigation-free pallets.
