HT Alloy Furnace Support Grate | Heat Treatment Fixture – FH®

Product Specification

HT Alloy Furnace Support Grate | Heat Treatment Fixture – FH®
Heat-Resistant Furnace Support Grate for Industrial Heat Treatment

FH® (Wuxi Junteng Fanghu Alloy Technology Co., Ltd.) manufactures custom furnace support grates and heat treatment fixture components for high-temperature industrial furnace applications.

This support grate is manufactured from HT heat-resistant alloy and measures 832 × 190.5 × 25.4 mm. Its elongated slotted structure combines load support with a high open-area ratio, helping furnace atmosphere and heat circulate around the loaded components during thermal processing.

Designed for repeated high-temperature service, it can be used individually or integrated into a complete heat treatment tray, rack, basket, or furnace loading fixture system.

Product Specifications

HT Heat-Resistant Alloy
HT alloy is a heat-resistant cast alloy commonly selected for furnace components exposed to elevated temperatures and repeated thermal cycling.

For heat treatment fixture applications, material selection must consider more than maximum furnace temperature. Important factors include:

• Furnace atmosphere
• Heating and holding time
• Loading weight
• Thermal cycling frequency
• Cooling method
• Required oxidation resistance
• High-temperature creep requirements

FH® can also provide alternative heat-resistant alloy grades according to the customer's actual working conditions.

Long Slotted Structure
The support grate incorporates multiple parallel longitudinal openings across the working surface.

This structure provides several practical advantages:

• Good furnace atmosphere circulation
• Efficient heat transfer around the load
• Reduced unnecessary fixture mass
• Stable support across the full length
• Improved heating and cooling efficiency

Compared with a solid support plate, the open-grate design allows heat and process atmosphere to move more freely through the fixture.

Designed for Furnace Loading Support
With an overall length of 832 mm and a low-profile thickness of 25.4 mm, this component is designed to provide a stable supporting surface without occupying excessive furnace space.

Depending on the furnace configuration, it can be used as:

• Workpiece support grate
• Furnace loading support
• Heat treatment rack component
• Tray supporting component
• Intermediate fixture support
• Custom furnace tooling component

The end openings can also serve as locating, connecting, or assembly features depending on the fixture design.

Built for Repeated Heat Treatment Cycles
Heat treatment fixtures experience continuous thermal loading:
Heating → Soaking → Cooling → Reloading

Over time, poorly designed fixtures may suffer from:

• Thermal deformation
• High-temperature creep
• Oxidation
• Cracking
• Dimensional instability

FH® combines appropriate heat-resistant alloy selection with structural design to manufacture furnace components suitable for repeated industrial service.

Typical Applications
This HT alloy furnace support grate can be used in:

• Carburizing furnaces
• Annealing furnaces
• Hardening furnaces
• Normalizing furnaces
• Batch furnaces
• Continuous furnaces
• Roller hearth furnaces
• Other industrial heat treatment systems

Typical supported workpieces may include:

• Automotive parts
• Gears
• Shafts
• Bearings
• Forgings
• Castings
• Mechanical components
• Other metal parts requiring heat treatment
