Metal Ceramic Chocky bars

weldability wear-resistant bar/liner （Chocky Bar）   is one of the highly alloyed chromium white iron wear parts and
looks like chocolate. the composite layer hardness is harder than high Cr material 3-4 times，The mild steel backing
plate has very good welding performance while bearing high impact.  
This product is very easy to use. It's easy to be cut and welded on curved surface without pre-heat or after heat
treatment. It's easy to be transported as it's very small. It's an ideal small area repairing wear part without too much
welding time. We have a complete range of specification and are able to customize and develop according to
customer's requirement.  Comparing with normal High manganese steel wear resistant casting wear parts, this
product's service life is 4-8 times longer.

This practice is suitable for Chocky bars only.
Note: For severe curves with a radius of less than 305mm, or inside curves, it is advisable to notch the mild  steel
backing plate opposite the “V” to assist forming. (Figure A)
The Chocky bar may crack during bending. This is normal.
1.  Clean the surface to which chocky bar will be welded.
2.  Tack weld one end of the chocky bar(as per the welding procedure) in at least  3 places by 15mm minimum
length per weld(Figure 1)
3.  Outside Curves: Hammer down unwelded end of bar with a soft face hammer to bend bar to match mating
radius. (Figure 2)
4.  Inside curves: Starting the center strike bar with a soft face hammer to bend bar to match mating radius.
(Figure 3)
5.  Cutting Details:    High pressure abrasive water jet cutting is the preferred cutting method. Thermal cutting
using an oxyacetylene torch, arc-air or plasma is NOT recommended due to high localized heat input and high
risk of cracking, cutting by abrasive disc is an accepted practice.
