The basic concept and application range of carbon structural steel

First, the basic concept and application range of carbon structural steel
Carbon structural steel refers to steel materials with a carbon content of no more than 2.11%, which are widely used in manufacturing, construction, metallurgy, shipbuilding, machinery manufacturing, petroleum and chemical industries. It has good plasticity, weldability and machinability, and the price is relatively low, with a relatively high cost performance.
Two, several types of steel commonly used in carbon structural steel
1. Q235 steel: It is a commonly used low carbon steel, mainly used in general engineering structure and mechanical manufacturing. It has the advantages of good strength, good ductility and low cost, and is widely used in Bridges, buildings, ships and other fields.
2. Q345 steel: It is a medium and high strength low alloy steel, which is widely used. It has higher strength and better ductility than Q235 steel, and is widely used in Bridges, ships, petrochemical and construction fields.
3. 20# steel: It is a commonly used carbon structural steel and is widely used. It has the advantages of high strength, good toughness, good wear resistance, etc., and is widely used in machinery manufacturing, auto parts, bearings, hammers and other fields.
4. 45# steel: It is a kind of advanced carbon structural steel with a wide range of applications. It has the characteristics of high strength, high toughness, good wear resistance, etc., and is widely used in the manufacture of excavators, machine tools, rail transit and other fields.
5. 65Mn steel: It is a medium carbon structural steel, mainly used in the manufacture of springs and stamping parts. It has good elasticity, bending resistance and corrosion resistance, and is widely used in automobile, machinery manufacturing, ships and other fields.
In general, the choice of carbon structural steel mainly depends on the specific application field and use environment. In different fields and environments, the appropriate steel grade should be selected to ensure the use effect and saf
