1.4852 + 310S Triangular-Frame Heat Treatment Fixture | FH® Alloy

1.4852 + 310S Triangular-Frame Heat Treatment Fixture
1176 × 1000 × 1090 mm Custom Furnace Fixture for Heat Treatment
FH® Alloy manufactures custom heat treatment fixtures and high-temperature furnace tooling for industrial heat treatment applications.
This custom triangular-frame heat treatment fixture is manufactured from a combination of 1.4852 heat-resistant alloy and 310S stainless steel, with overall dimensions of 1176 × 1000 × 1090 mm.
The fixture adopts an open structural design with reinforced supporting sections, providing stable positioning for workpieces while maintaining sufficient space for furnace atmosphere circulation and heat transfer.
Its triangular-frame configuration is designed according to the customer's workpiece arrangement and furnace loading requirements.
FH® Alloy can customize the material, dimensions, support positions, loading structure and overall fixture geometry according to actual operating conditions.

Product Specifications

Triangular-Frame Fixture Design
Unlike a conventional heat treatment basket or tray, this product uses a triangular-frame structural configuration.
The geometry is developed around the customer's specific loading requirements and provides dedicated support positions for the parts being heat treated.

The triangular-frame design can help achieve:

• Stable workpiece positioning
  
• Efficient use of fixture space
  
• Controlled spacing between workpieces
  
• Good structural rigidity
  
• Open furnace atmosphere circulation
  
• Convenient loading and unloading
  

The angle, support spacing and structural layout can all be redesigned for different components.

1.4852 + 310S Material Combination
This heat treatment fixture uses 1.4852 and 310S in different structural sections.
The use of two materials allows the fixture design to match the different thermal and structural requirements of individual components.

1.4852 Heat-Resistant Alloy
1.4852 is commonly used for high-temperature furnace fixtures and structural components.
Typical characteristics relevant to furnace applications include:

• Good high-temperature strength
  
• Good oxidation resistance
• Good dimensional stability
  
• Suitability for repeated heating cycles
  
• Good performance in industrial furnace environments
  

310S Stainless Steel
310S is widely used for fabricated heat-resistant components because of its combination of:

• High-temperature oxidation resistance
  
• Good weldability
  
• Good fabrication performance
  
• Suitability for furnace structural components
  

Material selection should always be based on the complete operating environment rather than temperature alone.

Open Structure for Heat and Atmosphere Circulation
Heat treatment fixtures should support the workpieces without unnecessarily blocking furnace atmosphere or heat transfer.
This fixture therefore uses an open-frame structure with large free-flow areas between structural sections.

The design can help provide:

• Better furnace atmosphere circulation
  
• More uniform exposure of workpieces
  
• Efficient heat transfer
  
• Improved cooling media flow
  
• Reduced unnecessary fixture mass
  

For different workpieces, FH® Alloy can adjust the support density and opening arrangement.

Reinforced Structure for High-Temperature Service
Industrial heat treatment fixtures operate under repeated thermal and mechanical stress.

During service, the fixture may experience:

• Thermal expansion
  
• Thermal contraction
  
• High-temperature creep
  
• Oxidation
  
• Mechanical loading
  
• Thermal fatigue
  
• Long-term dimensional change
  

For this reason, fixture design should consider both high-temperature strength and structural stability.
The reinforced sections of this triangular-frame fixture are arranged to support the loaded parts while maintaining sufficient open space around the workpieces.

Designed Around the Workpiece
A custom heat treatment fixture should not be designed only according to the furnace dimensions.
The actual workpieces are equally important.

FH® Alloy can design fixture supports according to:

• Part shape
  
• Part diameter
  
• Part length
  
• Individual part weight
  
• Number of parts per fixture
  
• Required orientation
  
• Required spacing
  
• Loading and unloading method
  

This allows the fixture structure to match the actual production process rather than using a generic basket design.

Suitable Heat Treatment Applications
This type of custom heat treatment fixture can be designed for processing:

• Gears
  
• Shafts
  
• Rings
  
• Sleeves
  
• Bushings
  
• Automotive components
  
• Transmission parts
  
• Forged components
  
• Mechanical parts
  
• Other precision metal components
  

The support layout can be modified for different component geometries.

Furnace Applications
Custom triangular-frame heat treatment fixtures can be developed for different industrial furnace systems, including

• Carburizing furnaces
  
• Atmosphere furnaces
  
• Hardening furnaces
  
• Annealing furnaces
  
• Batch heat treatment furnaces
  
• Continuous furnace systems
  
• Other industrial thermal processing equipment
  

For carburizing and other controlled-atmosphere applications, the fixture structure should be evaluated together with the temperature, atmosphere, cycle time, load and cooling method.

Manufacturing Process
A custom triangular-frame heat treatment fixture may involve:
Requirement Review → Fixture Design → Material Selection → Casting → Machining → Fabrication → Welding → Assembly → Dimensional Inspection → Final Inspection

Quality Inspection
Before shipment, key inspection items may include:

• Overall dimensions
  
• Fixture geometry
  
• Support position accuracy
  
• Structural alignment
  
• Weld condition
  
• Assembly fit
  
• Surface condition
  
• Critical locating dimensions
