What is 22SiMn2B steel plate

22SiMn2B steel plate is a kind of high-strength manganese-resistant steel, which is mainly used to withstand harsh working conditions such as impact, extrusion, and material wear.

22SiMn2B steel plate is widely used because of its simple chemical composition and good process performance. With the continuous development of the machinery industry, the performance requirements for steel plates for equipment manufacturing are becoming more and more stringent. Under the current situation, the successful development of 22SiMn2B steel plates as steel for construction machinery plays a crucial role.

Chemical elements and content of 22SiMn2B steel plate:
C: 0.19-0.25%,
Si: 0.70 to 1.00%,
Mn: 1.50-1.85%,
P≤0.025%,
Ti: 0.010-0.060%,
B: 0.0005-0.035%,
The balance is Fe and inevitable impurities.

22SiMn2B steel plate is used for the welded joints of loader buckets. The addition of a trace amount of boron to the steel can significantly change the properties of the steel. The main function of boron is to improve the hardenability. Excessive boron or improper heat treatment will lead to the precipitation of boron phase, causing the properties of steel are reduced.
