Grade 204 Cu Stainless Steel Coils/Strips
200 SERIES STAINLESS STEEL
Hot rolled stainless steel strip is a strip with a thickness of 1.80mm to 6.00mm and a width of 50mm to 1200mm, which is produced by the hot rolling mill.
Hot-rolled stainless steel strip refers to a product that is produced through a hot rolling process applied to stainless steel coils.
Hot rolled stainless steel strip has many advantages such as low hardness, easy processing and good extensibility.
Its production process is pickling, high temperature rolling, process lubrication, annealing, smoothing, fine cutting, and packaging.
Hot-rolled stainless steel strip has some distinctive characteristics. It typically has a darker, rougher surface compared to cold-rolled stainless steel strip due to the scale formed during the heating process.
The mechanical properties of hot-rolled strip include lower hardness and higher ductility compared to its cold-rolled counterpart. Hot-rolled strip also tends to have a wider dimensional tolerance range.
Hot-rolled stainless steel strip finds applications in various industries. It is commonly used in structural components, construction materials, automotive parts, pipe and tube manufacturing, and general fabrication. The material’s lower cost and faster production process make it suitable for applications where tight dimensional tolerances and a smooth surface finish are not critical.
