Cold Rolled Steel Sheets IS 513:2016 is a type of steel that has been processed through a cold rolling process to achieve a precise thickness, improved surface finish, and enhanced mechanical properties. This standard specifies the requirements for cold-rolled steel sheets and strips for general engineering purposes.
Surface Finish: Cold-rolled steel sheets have a smoother finish compared to the rough surface of hot-rolled sheets. Strength: Cold rolled sheets have higher strength due to the work hardening process during rolling. Dimensional Accuracy: Cold rolled sheets offer better dimensional accuracy and tolerances. Cost: Cold-rolled steel sheets are generally more expensive than hot-rolled sheets due to the additional processing steps.
Cold-rolled steel sheets are classified into various grades based on their chemical composition and mechanical properties, with IS 513:2016 CR1 being a commonly used grade for general applications. These sheets have a maximum carbon content of 0.15%, manganese up to 0.60%, sulphur up to 0.035%, and phosphorus up to 0.035%. They exhibit mechanical properties such as tensile strength between 270-410 MPa, yield strength between 140-280 MPa, and a minimum elongation of 28%. Cold-rolled steel sheets feature a superior surface finish compared to hot-rolled sheets, making them ideal for applications requiring a smooth surface. The cold rolling process ensures precise control over thickness, width, and length, resulting in excellent dimensional accuracy. The controlled manufacturing process enhances their mechanical properties, including strength and flexibility, and their high formability makes them suitable for various forming and stamping operations. While not inherently corrosion-resistant, cold-rolled steel sheets can be coated or treated for improved durability.
Cold Rolled Steel Sheets IS 513:2016 CR2, available through IndiaSteelHub, are premium steel sheets processed through a meticulous cold rolling process, designed to offer higher strength and improved mechanical properties compared to CR1 grade, making them suitable for applications requiring enhanced durability. The IS 513:2016 CR2 standard specifies the requirements for CR2 grade sheets, with a chemical composition of max 0.15% carbon, max 0.60% manganese, max 0.035% sulphur, and max 0.035% phosphorus. The mechanical properties include a tensile strength of 370-450 MPa, yield strength of 240-340 MPa, and a minimum elongation of 22%. CR2 grade sheets offer high strength, a superior surface finish, excellent dimensional accuracy, good formability, and the potential for improved durability through coating or treatment. Available in various sizes and thicknesses (commonly ranging from 0.3mm to 3.2mm, with standard sizes including 1000mm x 2000mm, 1250mm x 2500mm, and 1500mm x 3000mm), custom sizes can also be manufactured based on specific needs. The prices of cold-rolled steel sheets vary based on factors such as grade, thickness, size, and market conditions. For competitive pricing, IndiaSteelHub offers high-quality products at reasonable rates, and local suppliers can be found by searching for "cold rolled steel sheet near me". Compared to hot-rolled sheets, cold-rolled steel sheets have a smoother surface finish, higher strength due to the work hardening process, better dimensional accuracy and tolerances, and are generally more expensive due to additional processing steps. Cold Rolled Steel Sheets IS 513:2016 CR2 from IndiaSteelHub offer a combination of high strength, excellent surface finish, and precise dimensions, making them suitable for a wide range of applications in various industries, with an understanding of the specifications, characteristics, and differences between hot-rolled and cold-rolled steel sheets aiding in the selection of the right material for specific requirements.
Cold Rolled Steel Sheets IS 513:2016 CR3, offered by IndiaSteelHub, are premium steel sheets processed through an advanced cold rolling process, specifically designed for deep drawing applications, offering excellent formability and surface finish. The manufacturing process involves several critical stages: hot rolling (heating and passing steel slabs through rollers to form thinner sheets), pickling (an acid bath to remove scale and impurities), cold rolling (rolling at room temperature to achieve the desired thickness and surface finish), annealing (relieving internal stresses and improving flexibility), and skin passing (a final light rolling to enhance surface smoothness and achieve the desired mechanical properties).They are used in a wide range of applications, including the automotive industry (for manufacturing body panels, structural components, and other parts requiring deep drawing quality), appliances (production of refrigerators, washing machines, and other household appliances), construction (roofing, cladding, and structural components), electrical equipment (fabrication of cabinets, enclosures, and panels), and furniture (production of metal furniture and shelving). Cold-rolled steel sheets are available in various sizes and thicknesses to meet different application requirements, with common thicknesses ranging from 0.3mm to 3.2mm and standard sizes including 1000mm x 2000mm, 1250mm x 2500mm, and 1500mm x 3000mm, with custom sizes also available based on specific needs.
