Manufacture of SADEBO Composite Wear Plates


placa-antidesgasteThe SADEBO Composite Wear Plates, are metallic plates burning resistant made up of two layers:

  • The base plate, which gives tenacity and mechanical resistance
  • The contribution layer, which offers burning resistant characteristics

The Base Plate is made up of welding material and faisable to be able to work with normal tools. The contribution layer is a high alloy material composed of Chrome Carbures.


SADEBO offers three Wear Plate types according to different customer applications:

  • SADEBO 100 with a hardness matrix 58,0 Rockwell C
  • SADEBO 200 with a hardness matrix 62,5 Rockwell C
  • SADEBO 300 with a temperature resistance up to 800° C


  • Chemical composition: 4,5% C, 28,5% Cr
  • Components: 56% Chrome Carbide, 44% Steel alloy Matrix
  • Partial duration: Chrome Carbide: 870 Brinell (1.500 vickers) Steel Carbide: 615 Brinell (58 Rockwell C)
  • Middle duration: 742 Brinell

The microstructure is made up of a martensite matrix and primary fine carbides of polygonal type equally delivered. It can also have some polygonal carbides of acicular type. This structure concedes high resistance to wear properties.

  1. Maximum length, even more than 20 times a steel piece without recharging
  2. Maximum reliability minimizing the ruptur risk piece
  3. They reduce the production stoppage in a considerable way, making possible its planning fitting to its needs
  4. Personal cost saving of replacement pieces
  5. They avoid the sales loss during the production stoppages
