ABRAPLATE®, ERGOTEM’s bi-metallic wear plate, is a unique chromium carbide overlay plate on a mild steel base. Its excellent wear and abrasion resistant properties ensure extended service life of equipment, while reducing maintenance costs.
ABRAPLATE® is produced by a unique and versatile automatic bulk welding method, using the highest quality raw materials offering superior wear resistance & high durability versus mild steel as verified by ASTM G65 testing. Our fully automated production method and our quality control procedures secure a product with homogenous chemical analysis and hardness throughout the clad overlay.
The base material used is mainly S235JR steel which allows the end product to be easily welded & formed in complex structures. Other steel qualities can be used as base plate including stainless steel, AR and other special steel qualities which are required in specific applications according to customer needs.
Plates and fabrications have excellent wear resistance performance and are easily installed on various types of equipment, extending their lifetime, while offering cost-efficient protection. ERGOTEM’s design, manufacturing and fabrication expertise guarantees increased return on wear investment and thus peace of mind.

Hardfacing Patterns
ERGOTEM’s wear plates are offered mainly with straight longitudinal welding beads. Some special applications where material is flowing against equipment in irregular direction require for wave welding pattern (zig-zag shape) for extra protection.
Available hardfacing patterns include:
- Straight Longitudinal Welding Beads
- Wave Welding Beads
- Customized partially Welded pattern (upon request)
