High Temperature Alloy Gaskets

High Temperature Alloy (HTA) Gaskets
The HTA gasket is a single- or multiple-layer, high-temperature alloy substrate capable of sealing at service temperatures up to 1,000° C. Layers contain full or half embossments to provide functions that include localizing contact stress and responding to flange motion. A high-temperature coating is applied for enhanced microsealing and improved abrasion resistance.
Features and benefits include:
Effective exhaust gas sealing at service temperatures beyond conventional material capabilities (500° C+)
Mechanical properties of substrate materials maintained at service temperatures up to
1,000° C
Improved gasket resiliency
Ability to seal larger flange deflections
Portfolio of HTA material choices tailored to operating environment conditions
Installation features can be added (e.g., star holes, bolt holes)
Low creep relaxation for reduced flange bending and deflection
Improved bolt-load retention at elevated temperatures
High Temperature Alloy gaskets optimized for cost and performance
Delivers Optimized HTA grade for application requirements up to 1000°C
Up to 5X recovered height improvement (material creep resistance) from 450-1000°C
Non-oxidizing and thermally stable coating provides 35% –70% reduced coefficient of friction
