one、definition
Carbon steel plate is a steel plate material with carbon as the main alloying element,Its carbon content is usually in the range of0.05%arrive2.11%between。According to the different carbon contents,Carbon steel plates can be divided into low-carbon steel、Medium carbon steel and high carbon steel。Carbon steel plate has good processing performance、Welding performance and certain mechanical properties,It is one of the most commonly used metal materials in industrial manufacturing。
two、classification
(one)Classified by carbon content
mild steel(carbon content≤0.25%)
characteristic:Low carbon steel has relatively low strength and hardness,But it has good plasticity and toughness,Easy to process and weld。for example,Low carbon steel cold-rolled sheet is commonly used in manufacturing automotive bodies、Home appliance shells, etc。
application:Widely used in architecture、car、household electrical appliances、Fields such as mechanical manufacturing,Especially suitable for parts that require a large amount of stamping and forming。
medium carbon steel(carbon content0.25%~0.60%)
characteristic:Medium carbon steel has high strength and hardness,Has good comprehensive mechanical properties。After heat treatment,Its performance can be further improved。for example,After quenching and tempering treatment, medium carbon steel,Can be used to manufacture gears、Mechanical components such as shafts。
application:Mainly used for manufacturing various mechanical structural components、Transmission components, etc,Like the transmission shaft of a car、gear,And the spindle of the machine tool, etc。
high-carbon steel(carbon content≥0.60%)
characteristic:High carbon steel has high hardness and wear resistance,But poor plasticity and toughness。It is usually used to manufacture tools and components that require high wear resistance。for example,High carbon steel can be used to manufacture files after heat treatment、Tools such as saw blades。
application:Mainly used for manufacturing tools、mold、Springs, etc,Like spring steel、Cutting tool steel, etc。
(two)Classified by processing technology
Hot rolled carbon steel plate
characteristic:Hot rolled carbon steel plate is produced through high-temperature rolling,Has high production efficiency and low cost。Its dimensional accuracy is relatively low compared to cold-rolled steel plates,But the thickness and width range are relatively wide。for example,Hot rolled carbon steel plates are commonly used in building structures、Large scale projects such as bridges。
application:Suitable for those with low requirements for dimensional accuracy,But in situations where larger thickness and width are required,Like steel beams used in construction、Steel columns, etc。
Cold rolled carbon steel plate
characteristic:Cold rolled carbon steel plate is processed by cold rolling on the basis of hot rolling,High dimensional accuracy、Good surface quality、Advantages of high strength。for example,Cold rolled carbon steel plates are commonly used in the manufacturing of automotive bodies、Products such as household appliance casings that require high surface quality and dimensional accuracy。
application:Widely used in automobile manufacturing、Home appliance production、Fields such as mechanical manufacturing,Especially suitable for stamping、Welding and other processing techniques。
three、Performance characteristics
Good Processability
Moderate mechanical performance
Low cost
four、application area
construction industry
automobile making
Machinery manufacturing
Carbon steel plate can be used to manufacture various mechanical components,Like gears、axle、Springs, etc。After heat treatment, medium carbon steel and high carbon steel,Can meet the strength and wear resistance requirements of mechanical components。
