CRCA Coil & Sheets

CRCA Coil & Sheets

Cold rolled close annealed steel coils are made from Hot Rolled Coils. Cold Rolling is a process through which the Hot Rolled steel sheet or strip after Pickling process is introduced between rollers by application of high pressure at temperature below the re-crystallization temperature. This method basically imparts smooth surface finish, accurate thickness, high tensile strength, yield strength hardness with corresponding decrease inductility. Hence selection of proper combination of steel composition, degree of cold working and heat treatment play a pivotal role to produce cold rolled sheets / strips having diverse applications and mechanical properties suitable for a wide spectrum of end users.

NDC Processes Cold Rolled sheet in a variety of sizes, grades and surface finishes to meet specific end-use requirements. Cold Rolled Sheet is manufactured from hot rolled coils and Pickling to remove the surface oxide produced during the hot rolling stage, and cold reducing through a Cold Mill to the desired thickness.

Cold reducing steel produces an extremely low ductility product. It’s usually processed further to develop desired end use characteristics such as formability, surface texture, flatness, etc. These further reprocessing steps include annealing and temper rolling for formability and surface texture, and in some cases, tension levelling for flatness.

Typical uses for Cold Rolled Steel

Metal furniture, desks, filing cabinets, shelves, tables, chairs, motorcycle exhaust pipes, computer cabinet and hardware, all home appliances and components, shelving, lighting fixtures, hinges, tubing, steel drums, lawn mowers, electronic cabinetry, lighting fixtures, water heaters, metal containers, and a variety of construction related products.

Formability

Cold Rolled Steels can be used to produce parts containing simple bends to parts with extreme deep drawing requirements depending on the grade and mechanical properties selected. Cold-rolled sheet metal can be readily welded and is suitable for painting applications when the surface has been well cleaned.
