What role do the elements in AR400 wear-resistant steel plate play

Posted:2021-12-03 17:32:24

AR400 wear-resistant steel plate mainly contains the following important elements, so what are the main functions of these elements?

1. Carbon exists in all steel plates and is the most important hardening element. It is beneficial to increase the strength of the steel plate. We usually hope that the tool-grade steel plate contains more than 0.5% carbon, which becomes a high-carbon steel.

2. Chromium: increase wear resistance, hardness, and most importantly, corrosion resistance, more than 15% is considered stainless steel. Even so, all steel plates will rust if they are not properly maintained.

3. Manganese: an important element that helps to produce texture structure, increase hardness, strength and wear resistance.

4. The molybdenum carbonizing agent can prevent the embrittlement of the thick-walled AR400 wear-resistant steel plate and maintain the high temperature strength of the steel plate. It appears on many steel plates. Air quenched steel always contains 1% or more molybdenum, so they can harden in air.

5. Nickel: Maintain strength, corrosion resistance and toughness.

6. Silicon: Helps increase strength. Like manganese, silicon is also used in the production of steel to maintain the strength of the steel plate.

7. Tungsten: Enhance wear resistance.

The above is the introduction about the role of each element in AR400 wear-resistant steel plate.
