Frequently Asked Questions
What is the hardness of the wear resistant plate?
The chromium carbide overlay plate achieves a hardness range of 58-65 HRC (600 BHN), which is approximately five times harder than unplated mild steel.
Can these plates withstand high temperatures?
Yes, complex carbide overlays are designed to maintain full wear resistance in temperatures up to 600 °C (1100 °F).
What base materials can be used?
Standard base material is Q235, but we can also use A36, NM400, SS316, or HARDOX450 depending on application requirements.
Is it normal for the hard surface to have fine cracks?
Yes, fine cracks perpendicular to the welding bead are normal; they result from natural stress relieving in the very hard matrix and do not affect performance.
How can the plates be cut or machined?
Plasma cutting is the recommended method. Due to extreme hardness, machining is not recommended, though the surface can be ground.
What are the typical applications?
Typical applications include bin and hopper liners, slurry pipes, chute feeders, belt conveyors, and mining equipment.
