Laminated Chrome White Iron Wear Plates

Laminated Chrome White Iron Wear Plates

Laminated Chrome White Iron Wear Plates are unique wear resistant materials in that they combine very high wear resistant qualities of a white iron(ASTM A532 15/3CrMo, 700BHN–63HRc) with a weldable & high impact toughness mild steel through a metallurgical bond to create a product that is exceptionally resistant to impact and abrasion while retaining.

--Material: ASTM A532 CLASS II TYPE B Chrome white iron(15/3CrMo) vacuum brazed onto mild steel base plate.

  C  2.5-3.5 

  Cr 15-18

  Mn 0.5-1.0

  Mo 0.5-2.5

  Cu 0.5-1.0

--The minimum thickness for white iron wear casting we can make is 6mm, the maximum thickness 160mm.

Advantage: 

1. Hardness: 63HRC/700BHN. According to the feedback from our end users, the usage life is at least 2 times higher compared with overlay/hardfacing wear plates, at least 7 times longer than A.R type steels 360/400BHN. The thicker ones such as 20mm or above wear plates, usage life is much more longer. The wear resistant performance is the same from plate surface to the brazing joint.

2. Wear plate surface is smooth and flat, media is not easy to stick on.

3. Shapes and sizes can be made on request; Bolts, Nuts, Washers, Holes, Threads are available on request.

4. Better cost-efficient. 

5. Operating temperature: 550℃

Note: for big sheet size, plates will need to be splice, not a whole sheet. For example, wear plate 1500x400x25/6mm(25mm wear, 6mm base), the wear casting will be jointed with 4pcs, and mild steel base plate will be joint with 2pcs.
