20#Round Steel Introduction:

20No. round steelyouhziLow-carbon carbon steel, cold extrusion, carburized and quenched steel.20#Low tensile strength, good ductility, plasticity, and weldability. Tensile strength is:253-500MPa, elongation ≥24%。20#Round Steel Characteristics &15#Round steel is similar, but with slightly higher strength.

youhziCarbon structural steel has a lower content of sulfur, phosphorus, and other non-metallic inclusions compared to ordinary carbon structural steel. According to different carbon contents and applications, this type of steel is roughly divided into three categories: ① less than0.25%CCarbon steel, especially with a carbon content lower than0.10%The08F，08AlExtensively used for deep-drawing applications such as automotive parts and can manufacturing, etc., due to its excellent deep drawing and welding properties.20GIt is the primary material for manufacturing ordinary boilers. Additionally, low-carbon steel is widely used as carburizing steel in the machinery manufacturing industry. ②0.25～0.60%CCarbon steel, often used in tempering condition, for manufacturing parts in the machinery manufacturing industry. ③ Greater than0.6%CHigh-carbon steel, commonly used in the manufacture of springs, gears, rolling mill rolls, etc. Depending on the manganese content, it can be further categorized into different manganese levels.(0.25～0.8%)With higher manganese content(0.7～1.0%And0.9～1.2%)Two steel groups. Manganese can improve the quenchability of steel, strengthen the ferrite, and enhance the yield strength, tensile strength, and wear resistance of the steel. Usually, a mark is appended to the grade number of high-manganese steel."Mn", such as15Mn、20MnTo differentiate from carbon steel with normal manganese content.

20#Round steel20It refers to the carbon content, the carbon content is0.2%It belongs to low-carbon steel. Steel can be categorized into low-carbon, medium-carbon, and high-carbon steel.
