Stellite coating is a specialized hard-facing solution designed to protect thermowells and temperature sensors operating in highly abrasive and erosive industrial environments. At Acez, we apply a premium cobalt-chromium-tungsten alloy coating to reinforce exposed sensor surfaces, significantly extending service life in applications where standard stainless steel materials would rapidly degrade. This advanced surface enhancement is ideal for industries facing constant particulate impact, high-velocity flow erosion, and severe mechanical wear.
In demanding process conditions, sensors are often exposed to slurry flow, ash particles, aggressive solids, and turbulent gases. Without proper protection, these forces can thin the sensor sheath, compromise measurement accuracy, and lead to premature failure. Stellite hard-facing technology provides a durable barrier that maintains structural integrity even under extreme operating conditions.
Our Stellite coating process ensures long-term reliability and metallurgical strength:
-
Cobalt-Chromium-Tungsten Alloy Application – Industry-proven material known for exceptional hardness and wear resistance.
-
Welded Metallurgical Bonding – Coating is fused to the base material for superior adhesion and durability.
-
Enhanced Abrasion & Erosion Resistance – Protects against particulate-laden flows and mechanical wear.
-
Extended Sensor Service Life – Reduces frequency of replacement and maintenance shutdowns.
-
Optimized for Harsh Industrial Environments – Suitable for extreme process conditions.
This protective solution is particularly valuable in fluidized bed reactors, coal-fired power plants, cement kilns, mining operations, and heavy industrial processing facilities where abrasive conditions threaten instrumentation longevity. By investing in wear-resistant sensor coatings, operators can reduce downtime, improve reliability, and lower total lifecycle costs.
Maximize the durability of your temperature measurement systems in the harshest environments. Contact Acez today to discuss Stellite coating solutions for your thermowells and industrial sensors.
