SPA-H is the first generation of container steel products, with mature technology and stable quality, and has been widely used in marine logistics containers. LGC450 and LGC550 are the second generation of high-strength container steel, featuring the same weather resistance index as the first generation. Through micro-Ti treatment, the yield strength has been increased by 100–200 MPa. This type of container steel is widely used in highway and railway container transportation, characterized by high strength, easy processing and forming, as well as energy saving and weight reduction.
