HC340LA High Strength Cold Rolled Steel Coil – Automotive Structural Grade
Product Overview
High Strength Low Alloy (HSLA) cold rolled steel is a lightweight structural material designed for load-bearing automotive and industrial components. This HC340LA grade is micro-alloyed with niobium and titanium to achieve high strength while maintaining good formability and weldability. It enables significant weight reduction compared with standard mild steel, making it the material of choice for automotive lightweighting and structural efficiency initiatives.
Why Choose CNB High Strength Cold Rolled Steel?
Our high strength cold rolled steel is sourced from leading automotive steel mills with strict control over micro-alloying elements and thermo-mechanical processing. Every batch undergoes full mechanical testing including tensile, yield and elongation verification to ensure consistent performance. We offer a full range of HSLA and advanced high strength steel (AHSS) grades to match different strength and forming requirements for automotive and industrial applications.
