Special Chromium-Niobium-Boron alloy designed to give extreme resistance to high stress and gouging abrasion, and achieve a very high hardness in one pass deposits. The deposits will show stress relief cracks.

SUITABLE FOR

Bucket teeth and lips on bucket-wheel excavators in coal and phosphate mines, brick and clay mill augers, bucket teeth and lips on shovel buckets and bulldozer blades working in sand, wear plates and screens in the coal industry.

Microstructure : Complex carbides in an austenitic matrix
Machinability :Grinding only
Oxy-acetylene cutting : Cannot be flame cut
Deposit thickness : 2 layers maximum
Shielding gas : If required, Argon 98% + Oxygen 2%
Metal cored.

Martensitic Chromium-Titanium alloy designed to resist high stress abrasion with heavy impact. Deposits usually do not relieve cracks.

SUITABLE FOR

1Crusher rollers, crusher hammers, asphalt mixer blades, agricultural tools, shovel bucket teeth and lips, bulldozer blades, cane knives and shredders, bed knives in the wood pulp industry.

Microstructure : Finely dispersed Titanium carbides in a hard Chromium martensitic matrix
Machinability : Grinding only
Oxy-acetylene cutting : Cannot be flame cut
Deposit thickness : 15 to 18 mm in 5 to 6 layers
Flux cored

High Chromium carbide alloy designed to resist high stress grinding abrasion coupled with low impact. The deposits will readily show stress relief cracks.

SUITABLE FOR

Refurbishment of Ni-Hard coal pulverizing rollers, shovel bucket teeth and lips handling sand, pipes and bends.

Microstructure : Primary Chromium carbides (70%) and eutectic carbides in an austenitic matrix
Machinability : Grinding only
Oxy-acetylene cutting : Cannot be flame cut
Deposit thickness : 10 to 12 mm maximum in 2 to 3 layers
Metal cored

Chromium-Niobium-Molybdenum alloy with addition of Tungsten and Vanadium designed to resist high stress grinding abrasion with low impact and solid erosion at service temperatures up to 650°C. The deposits will readily show stress relief cracks.

SUITABLE FOR
