JIS G3445 STKM11A steel contains a small amount of silicon (Si) and manganese (Mn) in addition to carbon (C) and deoxidation (usually not more than 0.80%, up to 1.20%). This steel must have a chemical composition as well as mechanical qualities. The concentration of sulfur (S) and phosphorus (P) impurities is typically kept below 0.035%. High-quality steel has P and S controlled below 0.025% and 0.020%, respectively, and its grade should be appended with "E" for distinction. Other residual alloy elements introduced into steel by raw materials, such as chromium (Cr), nickel (Ni), and copper (Cu), are typically managed to be less than 0.25% chromium, 0.30% nickel, and 0.25% copper. Some brands of manganese (Mn) steel have a manganese (Mn) content of 1.40%.

JIS G3445 STKM11A steel is widely used due to its high production and cost-effectiveness. It can be forged into various shapes such as round, square, and flat sections, plates, and seamless steel tubes. The steel is commonly used in the manufacturing of general structural and mechanical structural parts, building structural components, and pipes for fluid conveyance. Depending on the application, heat treatment such as normalizing or quenching may be necessary.
