What are the properties of NM450 wear plate?

The properties of NM450 wear plate

1. Good impact resistance and wear-resistant composite steel plate base plate is low carbon steel or low alloy. Tough materials such as stainless steel reflect the superiority of bimetal. The wear-resistant layer resists the wear of the wear medium, and the substrate bears the load of the medium, so it has good impact resistance. It can withstand the impact and wear of the high drop hopper in the material conveying system.

2. The wear-resistant layer of a better heat-resistant alloy is recommended to be used under ≤600℃. If vanadium is added to the alloy wear-resistant layer, NM450 wear-resistant plates are sold, and alloys such as molybdenum can withstand high temperatures ≤800℃. Wear.

The recommended operating temperature is as follows: Ordinary carbon steel substrate is recommended to be used under 380℃; low alloy heat-resistant steel plate (15CrMo, 12Cr1MOV, etc.) is recommended to be used under 540℃; heat-resistant stainless steel substrate is recommended to be used under Use at 800℃ working condition. .

3. The alloy layer of a good corrosion resistance wear-resistant composite steel plate contains a high percentage of metallic chromium, so it has certain rust and corrosion resistance capabilities. It can be used to prevent coal sticking when used in coal droplets and hoppers.
