The EN 10149-2 standard has a specific range of requirements for the chemical composition of materials. These requirements ensure the quality and performance of steel. The specific chemical composition requirements may vary depending on the material classification, but usually include the content range of carbon (C), silicon (Si), manganese (Mn) and other elements. In addition, there may be clear content limits for other elements such as phosphorus (P), sulfur (S), niobium (Nb), vanadium (V), titanium (Ti), etc.
The EN 10149-2 standard mainly focuses on the technical conditions and delivery requirements of hot-rolled flat steel, coils and wide steel products. The steel products will undergo strict inspection to ensure that they meet the technical requirements of the EN 10149-2 standard.
The EN 10149-2 standard has a wide range of applications. It is mainly applicable to fine grained steel for hot-rolled deformable purposes, including wide steel, coils and flat steel. First of all, it has a wide range of applications in the field of automobile manufacturing. It is often used in the manufacturing of automotive parts, such as body structural parts, chassis parts and suspension systems. Secondly, it is used in the construction and civil engineering fields to manufacture pidges, building structures, pipes and other building components. In machinery manufacturing, these steels can be used to manufacture various mechanical parts and equipment; in the energy field, they can be used to manufacture oil and gas pipelines, wind power equipment, etc.; in shipbuilding, these steels are used for their corrosion resistance and High strength and widely used.
