Oil & Gas Applications

Our Stellite alloy components solve critical failure challenges under high-temperature, sour gas, abrasive drilling fluid and thermal cycling working conditions.

MWD/LWD Sensor Housings

Maintain precise data reading in high-temperature downhole formations and resist degradation caused by sour gas environments.

Stellite-Coated Augers

For decanter centrifuges with HRC hardness above 55. Withstand severe abrasion from drilling fluids, triple equipment service life and cut maintenance workload by 40%.

API Pump Seal Rings

Fabricated from Stellite alloys eliminate sand-induced erosion and retain reliable sealing performance under repeated temperature fluctuation cycles.

All our Stellite products are engineered to tackle severe wear, corrosion and high-temperature challenges across oil & gas, petrochemical, steel and power generation industries, with flexible supply of standard blank materials and fully drawing-customized machined parts to match unique on-site operational requirements worldwide.
