CRC SHEET

Product Description

Cold Rolled Mild Steel (CRMS) sheet is a versatile and widely used material known for its excellent surface finish, precise dimensions, and improved mechanical properties compared to its hot-rolled counterpart.

Manufacturing Process: CRMS is produced from hot-rolled steel coils that have been pickled (to remove scale) and then passed through a series of rollers at room temperature. This cold reduction process refines the grain structure, increases hardness and tensile strength, and reduces ductility.

Key Characteristics:

• Surface Finish: Exhibits a smooth, clean, and bright surface, often free from scale and imperfections, making it ideal for applications requiring aesthetic appeal or subsequent coating.
• Dimensional Accuracy: Offers tight tolerances on thickness and width, ensuring consistency in manufacturing processes.
• Mechanical Properties:
  • Increased Hardness: The cold working process makes the steel harder.
  • Higher Tensile Strength: It can withstand greater pulling forces before deforming.
  • Reduced Ductility: It is less malleable and may be more prone to cracking under severe forming operations compared to hot-rolled steel. However, for many applications, it retains sufficient formability.
• Formability: While less ductile than hot-rolled, CRMS is still highly formable and can be bent, stamped, and drawn into various shapes.
• Weldability: Generally possesses good weldability using common welding techniques.
• Cost-Effective: A relatively economical material for its properties and wide range of applications.

Typical Applications:

CRMS is extensively used in a vast array of industries, including:

• Automotive Industry: Body panels, structural components, and interior parts.
• Appliances: Refrigerator and washing machine casings, oven components.
• Furniture: Desks, chairs, filing cabinets.
• Construction: Metal studs, door frames, roofing panels (when galvanized or coated).
• Electrical Enclosures: Cabinets, panels, and housings for electrical components.
• Consumer Goods: Tools, toys, and various household items.
• General Manufacturing: Brackets, fittings, and other fabricated parts.

In summary, Cold Rolled Mild Steel sheet is a preferred choice for applications demanding a superior surface finish, precise dimensions, and enhanced strength, making it a cornerstone material in modern manufacturing.
