High quality structural steel This kind of steel must have both chemical composition and mechanical properties. Its brand is a two-digit representation of the average carbon mass fraction in steel ten thousand points (ω) *10000). For example, 45 steel indicates that the average mass fraction of carbon in steel is 0.45%; 08 steel indicates that the average mass fraction of carbon in steel is 0.08%. High quality carbon structural steel is mainly used to make machine parts. It is generally heat treated to improve mechanical properties. Depending on the carbon mass fraction, it has different uses. 08, 08F, 10, 10F steel, high plasticity, toughness, has excellent cold forming performance and welding performance, often cold rolled into sheet, used to make instrument shell, automobile and tractor cold stamping parts, such as car body, tractor cab; 15, 20, 25 steel is used for the production of small size, light load, surface requirements of wear resistance, core strength requirements are not high carburized parts, such as piston pin, template, etc. 30, 35, 40, 45, 50 steel after heat treatment (quenching + high temperature tempering) has good comprehensive mechanical properties, that is, has high strength and high plasticity, toughness, used to make shaft parts, such as 40, 45 steel is often used in the manufacture of automobile, tractor crankshaft, connecting rod, general machine tool spindle, machine tool gear and other small force shaft parts;
