High strength steel plate is divided into Q390, Q420, Q460, Q550 and Q690 models, which have the characteristics of high strength and strong welding performance, so they are commonly used in all kinds of large welded parts.
High strength steel plate is divided into Q390, Q420, Q460, Q550 and Q690 models, which have the characteristics of high strength and strong welding performance, so they are commonly used in all kinds of large welded parts.
However, the micro-alloy elements contained in different models of steel plates are different. The higher the micro-alloy content, the higher the strength of the steel, and thus the carbon content in the steel will also increase.

High-strength wear-resistant steel is developed on the basis of low-alloy high-strength weldable steel with good wear resistance and a service life of several times that of conventional plan steel plates.
The production process is relatively simple. The method of quenching and tempering directly after rolling is generally used, or the controlled rolling and cooling process is used to stop strengthening. The content of alloying elements in high-strength wear-resistant steel is relatively small, usually 1% ~ 3%.
It can meet the application requirements of large construction machinery in harsh environment such as high wear resistance, short life and simple cold forming.
Performance and wear resistance of high strength steel plate:According to IRMCO technology first station and years of application experience, high strength steel plate stamping dies can meet the consumer demand and extend the die life without expensive coating cost.
It is mainly used for large ships, bridges, power station equipment, medium and high pressure boilers, high pressure vessels, and other large welded structural parts.
High strength plates are also widely used in various construction machinery, such as drilling rigs, electric shovels, electric wheel dump trucks, mining trucks, excavators, loaders, bulldozers, cranes, hydraulic supports for coal mines and other structural parts for various engineering constructions.
High strength steel plate can meet the long-term demand of energy construction and is an important support to ensure the safety of people and property in coal mine production operations.
