HC420LA is a 420MPa-class high-end cold-rolled microalloyed HSLA steel designed exclusively for automotive safety structures. As a mainstream upgraded material in the auto parts industry, it delivers exceptional rigidity, impact resistance, and durability.

HC380LA is a cold-rolled microalloyed high-strength low-alloy steel (HSLA) dedicated to the automotive industry. It features four core properties: high rigidity, excellent fatigue resistance, superior formability, and good weldability. It is specially designed to solve material challenges in mass stamping, vehicle load-bearing, and crash protection of automotive structural components.

HC340LA is a 340MPa-class cold-rolled microalloyed HSLA (High-Strength Low-Alloy) steel, serving as a core specialized material for manufacturing automotive structural components. It features high strength, high rigidity, excellent fatigue resistance, and superior formability. Produced by Da Ziran Steel via advanced continuous annealing, it achieves an optimal balance of load-bearing capacity, stamping formability, welding stability, and impact toughness, effectively resolving industry challenges such as deformation under long-term loading, stamping cracks, insufficient weld strength, and dynamic fatigue failure during vehicle operation.

HC300LA is a 300MPa-class cold-rolled microalloyed HSLA (High-Strength Low-Alloy) steel, and a widely used lightweight material for automotive component manufacturing. Produced via Nb/Ti microalloying grain refinement and precision continuous annealing, it delivers an ideal combination of consistent structural strength, excellent cold stamping formability, superior weldability, and flat surface quality.

HC260LA, B260LA and TSC260LA are 260MPa-class cold-rolled microalloyed HSLA (High-Strength Low-Alloy) steel coils. Produced using titanium-niobium microalloy grain refinement and precision continuous annealing, they solve the pain points of conventional cold-rolled steel: insufficient strength, cracking during stamping, and deformation during welding.

B410LA, HC410LA and TS410LA are high-end cold-rolled microalloyed HSLA (High-Strength Low-Alloy) steel products. Refined through niobium and titanium microalloying technology, they combine ultra-high structural rigidity, dimensional stability and excellent formability. Developed specifically for automotive lightweighting and heavy-duty structural components, the 410LA series achieves an ideal balance among high strength, stamping formability and weldability. B410LA, HC410LA and TS410LA are nearly identical in performance and fully interchangeable, making them the standardized structural steel of choice for global automotive OEMs and precision machinery manufacturers, suitable for a wide range of high-end industrial applications.
