Manufacturing Process
Hot rolled stainless steel coil is manufactured by heating billets or slabs to a temperature above 1100°C (2012°F) and passing them through rolling mills to reduce thickness. The coil is then annealed and pickled to remove scale, improving surface quality and corrosion resistance. Final coils are edge-trimmed and prepared for custom processing.
FAQ
Q: What is the difference between hot rolled and cold rolled stainless steel coils?
A: Hot rolled coils are thicker, less precise in finish, and better suited for structural applications, while cold rolled coils have tighter tolerances and a smoother surface.
Q: Can I request customized thickness and width?
A: Yes, we support custom dimensions according to project requirements, including thickness up to 16 mm and width up to 2500 mm.
Q: Which surface finish is standard for hot rolled coils?
A: No.1 finish (annealed and pickled) is standard, but black and shot-blasted finishes are also available.
Q: Are hot rolled coils suitable for pressure vessels?
A: Yes, especially in grades like 316L or 310S, hot rolled coils are used in high-pressure and high-temperature vessels.
Q: What grades are available for marine or salt-exposed environments?
A: For such environments, we recommend 316L or duplex stainless steel like 2205 for superior corrosion resistance.
