Cold Rolled Steel

Hot and Cold rolled steel

Understand the main differences between hot and cold rolled steel Hot and cold rolled steel are fundamental materials in the metal processing and manufacturing industries. Choosing between them isn’t about which is better, but about selecting the right material for the specific job. Understanding their distinct properties, manufacturing processes, advantages, and limitations is crucial for designers, engineers, and purchasers. The Core Difference lies in when and how the steel is rolled to achieve its final specifications 1. Hot Rolled Steel (HR): Process: Steel is heated significantly above its recrystallization temperature (typically above 1700°F / 925°C) until it glows. It’s then passed through rollers at this high temperature. Result: Easier shaping, […]

Home » Carbon Alloy Steel » Cold Rolled Steel Cold Rolled Steel Width: 600–1500 mm Thickness: 1.5 – 20mm Design Style: Customizable Product Introduce Cold Rolled Steel is a high-precision steel made from hot-rolled steel coils through room temperature rolling, annealing and other processes. Its core advantages: Surface quality: smooth and scale-free (Ra≤1.6μm), can be directly used for precision manufacturing. Mechanical properties: yield strength increased by 20%-50% (such as SPCC cold-rolled plate can reach ≥280MPa), and deep drawing performance is excellent (elongation 30%-45%). Dimensional accuracy: thickness tolerance ±0.03mm, suitable for high-precision scenarios such as automotive panels. Processing adaptability: supports surface treatment such as electrogalvanizing and spraying to meet diverse corrosion
