The characteristics and application of 20MnB5 steel plate

20MnB5 steel plate is a kind of low alloy high strength steel with excellent properties, which is widely used in many industrial fields.

20MnB5 steel plate features:

High strength: 20MnB5 steel plate has high strength and can withstand high pressure and impact and other working conditions.

Good plasticity: Although the hardness is higher, its plasticity is still good, and it is easy to process and forge, which helps to produce complex shapes and precise dimensions of parts.

Wear resistance: After proper heat treatment, high hardness and wear resistance can be obtained, which can extend the service life and improve the work efficiency.

It should be noted that the iron in the 20MnB5 steel plate is easy to react with oxygen to cause rust, so it is necessary to pay attention to protection and maintenance during use, and regularly apply anti-rust agents to extend the service life. At the same time, due to its large coefficient of thermal expansion, it is prone to deformation when subjected to high temperature heat treatment or heating, so it is necessary to control the temperature during processing and use, and take corresponding cooling measures.

The main chemical composition of 20MnB5 steel plate consists of 20% manganese, 0.25% carbon and 0.10% boron.

20MnB5 steel plate application:

Automotive industry: 20MnB5 steel plate is often used in the manufacture of automobile body, door, frame and other parts, as well as the brake disc and brake disc of the brake system, to provide better safety performance for the car.

Agricultural machinery: Due to its high strength and wear resistance, 20MnB5 steel plates are also widely used in the manufacture of agricultural machinery equipment, such as the blades and harrows of harvesters.

Construction engineering: In construction engineering, 20MnB5 steel plates are used to manufacture various mechanical parts, such as crane components and construction machinery accessories, to cope with high strength and wear resistance requirements.
