Cold Rolled Stainless Steel Coils are made from hot-rolled coils as raw materials and processed through multiple passes of pressing and drawing in a cold rolling unit. Cold Rolled Stainless Steel Coils are characterized by smooth and flat surfaces, better toughness and ductility, and higher strength and hardness. Commonly used materials for cold rolled stainless steel coils include 200 series, 300 series, 400 series and other stainless steel materials.
Application of Cold Rolled Stainless Steel Coil: Common usage including Construction, Surgery, Kitchen essential, Cold Stamping Parts. 304 stainless steel: construction of external banisters and handrails, and it has good processing performance and weldability. 316 stainless steel: For kitchen essentials such as equipment, cutlery and cookware, and it has good corrosion resistance and a wide range of shapes. 316L stainless steel: For medical and surgical applications, which demand high levels of reliable performance.
Product Features: Cold rolled stainless steel coils exhibit higher hardness and strength compared to their hot-rolled counterparts. They boast tighter tolerances, finer grains, and greater resistance to pressure and load, making them ideal for structural and mechanical parts requiring superior strength. Furthermore, the absence of oxide scale on the processed surface translates to cost and time savings in processing. Cold-rolled stainless steel coils offer high dimensional accuracy, excellent surface quality, and uniform thickness, catering to the demands of precision processing. Their exceptional surface quality, high smoothness, and lack of obvious flaws and defects make them well-suited for applications requiring stringent surface quality standards.
Advantages: Compared with hot-rolled stainless steel coils, cold-rolled stainless steel coils are cold-rolled and have no oxide scale on the surface, making the surface brighter and smoother; hot-rolled stainless steel coils have oxide scale on the surface and have a rough surface, and are industrial plates.
In terms of ductility, cold-rolled stainless steel coils have better ductility, stretchability, flatness, and stronger processing performance.
In terms of dimensional accuracy, cold-rolled stainless steel coils have higher dimensional accuracy and uniform thickness, which can meet the needs of precision processing. They have excellent processing performance and are suitable for occasions that require high dimensional accuracy.
No Holes or Cracks on the Surface: Cold-rolled stainless steel coils employ advanced production technology and rigorous quality control measures to ensure stable and reliable plate surface quality, thereby avoiding issues such as holes, cracks, and strip breakage.
No Oxide Scale Problem: Enhanced surface cleaning and treatment processes during production effectively prevent the formation of oxide scale, resulting in a clean and smooth surface for cold-rolled stainless steel coils. This improves appearance quality and extends the service life of the coils.
No Surface Oxidation Color: Special oxide scale removal processes and anti-oxidation treatment technologies are utilized to effectively inhibit the formation of surface oxidation colors. This ensures that the surface of cold-rolled stainless steel coils maintains consistent color and high smoothness, meeting your requirements for product appearance.
