H340LA is a cold rolled high strength low alloy (HSLA) steel grade designed with micro-alloying technology. It offers a high yield strength while maintaining excellent formability and weldability. This steel is widely used in automotive structural parts, machinery components, and metal fabrication where strength and weight reduction are required.

Chemical Composition Characteristics:

By adding micro-alloying elements such as Nb, Ti, and V, H340LA achieves refined grain structure and enhanced mechanical strength without significantly increasing carbon content, ensuring good ductility and processing performance.

Mechanical Properties (Typical):

Yield Strength: ≥ 340 MPa

Tensile Strength: approx. 410–510 MPa

Elongation: ≥ 18% (depending on thickness)

Available Specifications:

Thickness: 0.8 – 3.0 mm
