NM400 High Strength Abrasion Resistant Steel Plates For Construction Machine

NM400 high strength abrasion resistant steel plates for construction machine

nm400 wear-resistant plate
wear-resistant
The chemical composition of the wear-resistant layer of the alloy has a carbon content of 4 ~ 5% and a chromium content of 25 ~ 30%
Metallographic structure
In Cr7C3
carbide
The volume fraction is more than 50%, the macro hardness is HRC56 ~ 62,
Chromium carbide
The hardness is HV1400 ~ 1800. Because the carbide is vertically distributed in the wear direction, the wear resistance is more than doubled compared with the cast alloy with the same composition and hardness. The wear resistance of several typical materials is compared as follows:
(1) and
Mild steel
; 20 ~ 25:1
(2) as cast
High chromium cast iron
; 1.5 to 2.5:1
NM400 wear plate is high strength
Wear-resistant steel plate
, which has a high resistance to wear,
Brinell hardness
The value of 400 (HBW) is mainly to provide protection in the occasions or parts that need wear resistance, so that the equipment life is longer, reduce the maintenance and downtime brought by maintenance, and correspondingly reduce the investment of funds.
