HC340LA Profile
HC340LA is a cold-rolled, low alloy and high strength steel. As Nb-Ti micro-alloyed cold rolled sheet for high strength stamping, it is mainly used in low carbon steel. In addition to Si and Mn solution strengthening, Nb, Ti, V and other microalloying elements are added to form carbides and nitride particles with C and N elements, which are precipitated and strengthened on ferrite matrix by single or compound addition, then achieving higher strength. It is one of the preferred materials for structural parts and reinforcement parts.
Meet the requirements of different CCB tubes
According to the layout, the central pipe structure can be designed into different types: straight pipe, bend pipe and multiple steel pipe welded products.
CBIES AUTOMOTIVE can meet the deformation processing requirements of steel pipes.
