Amardeep Steel Centre is well-known as one of the leading stkm11a cold rolled tube manufacturer and supplier in all over country. IS G3445 STKM11A is the standard material for carbon seamless steel tubing used in mechanical parts.Carbon steels with a carbon content of less than 0.8 percent are considered high quality carbon structural steels. The steel has superior mechanical qualities and has less sulphur, phosphorus, and non-metallic impurities than carbon structural steel.

JIS G3445 STKM11A steel comprises a little amount of silicon (Si) and manganese (Mn) in addition to carbon (C) and deoxidation (usually not more than 0.80 percent , up to 1.20 percent ). It has no further alloying elements outside alloy elements (except residual elements). This steel must have a chemical composition as well as mechanical qualities. The concentration of sulphur (S) and phosphorus (P) impurities is normally kept below 0.035 percent. If it is controlled below 0.030 percent, it is high-quality steel, and its grade should be "A," such as 20A; if P and S are controlled below 0.025 percent and 0.020 percent, it is high-quality steel, and its grade should be appended after the grade. "E" stands 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 percent chromium, 0.30 percent nickel, and 0.25 percent copper. Some brands of manganese (Mn) steel have a manganese (Mn) content of 1.40 percent.

This steel has a high production and is widely used. It is typically forged into round, square, and flat sections, plates, and seamless steel tubes. It is primarily utilised in the production of general structural and mechanical structural parts, components, and building structural parts, as well as pipes for fluid conveyance. Heat treatment (normalising or quenching) may be required depending on the application.
