The difference between cold-rolled sheet and stainless steel is mainly reflected in three aspects, which are differences in use, characteristics, and raw materials.
1. The main use of cold-rolled sheet: mostly used in automobile manufacturing, electrical products, etc.
2. The main use of stainless steel: Most stainless steel products require good welding performance of raw materials, such as second-class tableware, thermos cups, steel pipes, water heaters, water dispensers, etc.
1. Characteristics of cold-rolled sheet: Because it has not been annealed, its hardness is very high (HRB is greater than 90), and its machinability is extremely poor. Only simple directional bending of less than 90 degrees can be performed (perpendicular to the coil). direction).
2. Characteristics of stainless steel: it has weldability, corrosion resistance, polishing performance and heat resistance.
1. Raw material of cold-rolled sheet: Cold-rolled sheet is a product made of hot-rolled coil as raw material and rolled at room temperature below the recrystallization temperature.
2. The raw materials of stainless steel: all contain 17-22% chromium, and the better steel also contains nickel.
