Stellite 190 Welding Hard Facing Powder Hardfacing Material For Petroleum Drill Bit

Factory Stellite 190 Welding Powder Hardfacing Material For Petroleum Drill Bit

Product Description

WLCo-190 is a highly abrasion-resistant alloy, primarily used for the hardfacing of bearing journals in tricone rotary rock bits used in the Oil and Gas Industry. Tricone bits operate in hot and extremely abrasive downhole conditions. Due to the high proportion of carbides, which provide the abrasion resistance, care must be taken to minimize cooling stresses incurred during hardfacing and to avoid service conditions which involve severe mechanical or thermal shock. It can only be finished by grinding.

WLCo-190 is not designed primarily as a corrosion resistant alloy, although it may be expected to have reasonable corrosion resistance to brackish water and mildly oxidizing environments. The high carbide content reduces its corrosion resistance relative to other CoCrW alloys, such as WLCo-6.
