Stellite 190 Welding Rod - Cobalt Based Alloy Hard Facing Rod Gouge Type Bearing Sleeve Drill Head

Product Description

Cobalt 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.

Common Names: Stellite 190 Polystel 190
