Refractory Anchors for Boilers & Furnaces | High-Temp Stainless Steel
Refractory anchors are engineered components designed to anchor refractory materials including:
Castables
Monolithic linings
Ceramic fiber modules
in high-temperature industrial applications. Manufactured from heat-resistant stainless steel alloys (304, 310S, 253MA), they provide critical resistance against:
✅ Extreme thermal cycling (up to 1150°C)
✅ Chemical corrosion in harsh environments
✅ Mechanical abrasion during operation
Essential for industrial furnaces, power plant boilers, and thermal processing equipment requiring reliable refractory retention systems.
Material Science Innovation
Our anchors leverage advanced metallurgy to solve critical challenges:
| Failure Mode | Solution | Material Benefit |
|---|
| Thermal deformation | Optimized V/Y geometries | 253MA alloy maintains integrity at 1100°C+ |
| Corrosion pitting | 310S chromium-nickel matrix | 25% Cr resists sulfidation in flue gases |
| Abrasive wear | Work-hardened surfaces | 40% increased hardness vs standard anchors |
