Description and applications
|
|
|
|
|
49 HRC
|
Good compromise for resistance to simultaneous abrasive wear and impact. Typical applications : garbage crusher hammers, crusher parts for relatively soft materials, schredders, sugar mills, cereal industry. |
|
|
|
|
61 HRC
|
Chromium carbide deposit with high abrasion resistance but limited resistance to impact. Low cost product used to resist wear from earth, sand, and abrasive. Typical applications : dredge pump components, mixers, riddle plates, wear plates. The weld metal cracks to relieve cooling stresses. |
|
|
|
|
60 HRC
|
Highly alloyed chromium carbide deposit for single-layer welding, very resistant to abrasion. Very limited resistance to impact. Typical applications : resisting wear from earth and sand. Examples : : dredge pump components, mixers, screw conveyors, screws for oil presses |
|
|
|
|
63 HRC
|
Used under conditions of severe abrasion with moderate impact. The dispersion of fine particles avoids wear by destruction of the matrix. Applications : dust extraction ventilators in the mining, cement and steel industries, rabbles, agricultural |
|
|
|
|
61 HRC
|
Used under conditions of severe abrasion with moderate impact. The stainless steel matrix is suitable for applications in corrosive media, notably in the food preparation industry : mixers, beaters, helices, screw-flights. |
|
|
|
|
55 HRC
|
Extremely high resistance to combined abrasion and corrosion. The very fluid weld pool gives excellent wetting. May be welded at low energy input to preserve the carbide particles throughout the matrix. Applications : oil drilling, food processing, chemical and rubber industries. |
