Weathering steel is mainly used for steel structures exposed to the atmosphere for a long time, such as railways, vehicles, bridges, towers, photovoltaics, and high-speed projects. It SPA-H rusty steel is used to manufacture structural parts such as containers, railway vehicles, oil derricks, seaport buildings, oil production platforms, and containers containing hydrogen sulfide corrosive medium in chemical petroleum equipment.

The main uses of flat steel are as follows. First, flat steel is used as a raw material for processing steel plates, which is convenient for transportation, takes up a small space, and can save transportation costs. Second, SPA-H rusty steel flat steel can be used as raw material for processing welded pipes. Flat steel can be a finished steel product, or it can be used as a billet for welded pipes and thin slabs for stacked sheets. Third, flat steel can be directly used as a steel structure. As a finished material, flat steel can be used for making hoop iron, tools and mechanical parts, and used as building frame structure and escalator in construction. Fourth, the flat steel has a smooth surface and a certain degree of beauty.

Vanadium is a weak deoxidizer. Adding vanadium into SPA-H rusty steel steel can reduce the adverse effects of carbon and nitrogen, effectively improve the strength, but sometimes also increase the tendency of welding hardening, vanadium is also a commonly used trace alloy element.

According to GBT3077, 42CrMo steel chemical composition should be within the range (%): 42CrMo carbon content is 0.38-0.45 (C), Silicon content is 0.17-0.37 (Si), Manganese content is 0.50-0.80 (Mn), Chrome content is 0.90-1.20 (Cr), Molybdenum content is 0.15-0.25 (Mo). The high Cr content contrivutes to high strength of 42CrMo steel, with min. yield strength of 930 Mpa, and min. tensile strength of 1080 Mpa. The common heat treatment for SPA-H rusty steel, 42CrMo steel is quenching and tempering.
