35#Round Steel Introduction:

35#Round steel baryouhziMedium-carbon carbon structural steel with good plasticity and adequate strength, good processing properties, and fair weldability, commonly used in normalizing and tempered conditions.35#Round steel is extensively used in the production of various forgings and hot-pressed parts, cold drawn and upsetting steel bars, seamless steel tubes, as well as components in mechanical manufacturing such as crankshafts, shafts, pins, levers, connecting rods, beams, sleeves, wheel hubs, washers, and bolts, nuts, motorcycle frames, and more.

youhziCarbon structural steel and ordinary carbon structural steel have lower contents of sulfur, phosphorus, and other non-metallic inclusions. Depending on the carbon content and application, this type of steel is roughly divided into three categories:①Less than0.25%CFor low carbon steel, especially those with carbon content below0.10%No Chinese content provided.08F，08AlWait, it is widely used for deep drawing parts such as automobiles and cans due to its excellent deep drawing and welding properties.……Please wait.20GIt is the primary material for manufacturing ordinary boilers. In addition, low-carbon steel is widely used as carburizing steel in the machinery manufacturing industry.②0.25～0.60%CCarbon steel with medium carbon content, commonly used in tempered condition, for manufacturing parts in the machinery manufacturing industry.③Greater than0.6%CHigh-carbon steel, commonly used in the manufacturing of springs, gears, rolling mill rolls, etc. Depending on the manganese content, it can be further divided 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 hardenability of steel, strengthen the ferrite, and enhance the yield strength, tensile strength, and wear resistance of steel. Usually, a mark is appended to the grade of high-manganese steel."Mn", such as15Mn、20MnTo differentiate from carbon steel with normal manganese content.
