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.
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 |
Optimized for boiler refractory linings. Max temp: 1100°C. Standard lengths: 75-300mm.
High-load capacity anchors for furnace walls. Corrosion-resistant up to 1150°C.
Reinforced design for cement castables. 310S grade for oxidation resistance.

Compliance: ASTM C862 and EN 1094-7 refractory anchoring standards
| Grade | Max Temp | Yield Strength | Key Applications |
|---|---|---|---|
| 304SS | 870°C | 205 MPa | Low-corrosion environments |
| 310S | 1150°C | 310 MPa | Oxidizing atmospheres |
| 253MA | 1100°C | 400 MPa | Cyclic thermal shock applications |
For maximum performance in refractory anchoring applications:
V-type anchors at 150-200mm spacing ensure uniform stress distribution in cementitious monolithic linings.
Quick-install T-anchors with 304SS speed clips reduce installation time by 40% vs welded solutions.
Y-shaped configurations withstand gas velocities exceeding 15m/sec in power plant boiler passes.
*All installation guidelines comply with ASTM C862 and EN 1094-7 refractory anchoring standards.
