Product Description


Product------Hard Overlay Welding Plates Series


    I. Technology Introduction


     Haweier hard-faced wear-resistant steel plate is kind of steel plate, which adopted the international leading metal arc welding production technology, welded a certain thickness wear resisting alloy layer on the surface of common low carbon steel or low carbon low alloy steel . The product wear-resisting layer has high hardness, with good wear-resistant properties. The basic plate is adopted good rolled plate with good toughness and plasticity. The alloy wear-resisting layer and the basic plate is metallurgical combination, which is strongly combined and cannot fall off.Under special technique, the surface of plate formed a directional grown eutectic structure, which make the wear resistance of hard-faced wear resistant steel plate HP100, HP200 and HP300 reached 14.6 times more than 16Mn steel plate.( Abrasive wear test as per ASTM G65)

FAQ

QQ20171012122235.jpg


Q1: Why are there so many cracks?


A1. Due to the cooling rates of dissimilar metals. Our hard facing plate for coal chute liner is manufactured by welding which results in high temperatures. During the cooling, the plate goes through a stress relieving which is a natural process and does not effect the performance of the plate. The stress relief cracks should be between 3/4" - 2" apart. The cracks can be touched up by our chrome carbide welding rod.


 


Q2: What is the best method of attachment?


A2. hard facing plate for coal chute liner is usually attached by countersunk bolts, welding studs, perimeter welding, or plug welding.Some methods are better suited than others depending on the specific application. For more detail on each method see the installation section.


 


Q3: Can hard facing plate for coal chute liner be drilled or machined?


A3. hard facing plate for coal chute liner cannot be machined or drilled. It can however be ground. Mild steel inserts are used to create countersunk or counter bored holes. hard facing plate for coal chute liner can be cut using plasma, Grinding wheel saw, or air-arc gouging.


 


Q4:MOQ?


Our product has no limit to quantity, it can be ordered according to customer requirement.


 


Q5: Whats the service life compare with Hardox series?


Generally speaking, our bimetallic overlay wear plate is 4.5~8 times than Hardox series in service life.
