Product Description
High Strength Automotive Steel/DC05/DC04/DC03/HC260LA/HC380LA/B250P1/B410LA
Cold rolled steel (CRS) is hot rolled steel that has been further processed at room temperature, increasing its strength by up to 20% through strain hardening. It offers superior surface finishes, closer dimensional tolerances, and higher hardness than hot-rolled alternatives. Common in precise applications, it is often used for furniture, appliances, and structural components.
Key Characteristics and Benefits
- Enhanced Strength & Hardness: Cold rolling process increases the yield and tensile strength, making it up to 20% stronger than hot-rolled steel.
- Superior Finish: The surface is typically smoother, shinier, and free of scale because it is processed at room temperature.
- Tight Tolerances: Because the material does not shrink, it can be manufactured to precise dimensions.
- Increased Ductility: While stronger, it is less brittle than hot-rolled steel due to further treatment steps.
