Product Introduction

Nm360 Hardfacing wear resisting steel plate

Wear-resistant steel plate properties:

1. Wear resistance

The chemical composition of the wear-resistant layer of the alloy carbon content of 4 ~ 5%, chromium content of 25 ~ 30%, the volume fraction of Cr7C3 carbide in the metallographic reaches more than 50%, the macro hardness is HRC56 ~ 62, the hardness of chromium carbide is HV1400 ~ 1800. Because the carbide is vertically distributed in the wear direction, the wear resistance is more than twice that of the cast alloy with the same composition and hardness. The wear resistance of several typical materials is compared as follows:

(1) with low carbon steel; 20 ~ 25:1

(2) with high chromium cast iron; 1.5 to 2.5:1

2, good impact resistance:

The substrate of the wear-resistant composite steel plate is low carbon steel or low alloy. Stainless steel and other ductile materials, reflecting the advantages of bimetal, wear-resistant layer against the wear of the wear medium, the substrate bears the load of the medium, so it has good impact resistance. Can withstand impact and wear such as high drop hoppers in material handling systems.

3, better heat resistance:

The wear layer of the alloy is used under the condition of ≤600℃. If vanadium, molybdenum and other alloys are added to the wear layer of the alloy, it can withstand the high temperature wear of ≤800℃.

The operating temperature is as follows:

Ordinary carbon steel substrate is not higher than 380℃ working conditions;

Low alloy heat resistant steel plate (15CrMo, 12Cr1MOV, etc.) substrate is not higher than 540℃;

Heat-resistant stainless steel substrate is used under conditions not higher than 800 ° C.

4, good corrosion resistance

The alloy layer of wear-resistant composite steel plate contains a high percentage of metal chromium, so it has a certain rust and corrosion resistance. It can be used to prevent coal sticking on occasions such as dropping coal barrel and funnel.
