Triangular Heat Treatment Fixture for Carburizing Furnace | FH® Alloy

Product Specification

1.4852 + 310S Triangular Heat Treatment Fixture for Carburizing Furnace
1176 × 1000 × 1090 mm custom heat-resistant fixture designed for industrial carburizing furnace applications.

FH® Alloy manufactures custom heat treatment fixtures for carburizing furnaces and other high-temperature industrial furnace applications.

This 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 features an open, reinforced frame structure designed for loading and supporting metal components during carburizing heat treatment. Its triangular rack-style configuration provides a stable support arrangement while maintaining sufficient open space for furnace atmosphere circulation around the workpieces.

The material, dimensions, loading structure, support positions and overall fixture configuration can all be customized according to the customer's furnace and heat treatment process.

Product Specifications

Designed for Carburizing Furnace Applications
Carburizing furnace fixtures operate under demanding thermal conditions.

During repeated production cycles, the fixture may be exposed to elevated temperatures, carburizing atmospheres, repeated heating and cooling, mechanical loading and long holding periods.

For this reason, heat treatment fixtures used in carburizing applications require careful consideration of both material selection and structural design.

This custom fixture uses 1.4852 and 310S in different structural sections according to the design requirements, combining heat-resistant materials with a reinforced open-frame construction.

The final fixture design should always be matched to the customer's actual:
Operating temperature, furnace atmosphere, cooling method, workpiece weight, cycle time and loading arrangement.

Triangular Frame Structure
A key feature of this product is its triangular rack-style structure.

Compared with a conventional rectangular basket, this configuration provides a different loading arrangement for components that need to be positioned or supported inside the furnace.

The triangular geometry can be designed to provide:

• Stable support during furnace operation
• Organized workpiece positioning
• Efficient use of fixture space
• Open access for furnace atmosphere circulation
• Convenient loading and unloading
• Reduced interference between different workpiece positions

The angle, frame dimensions and internal support positions can all be customized according to the customer's parts.

Open Structure for Furnace Atmosphere Circulation
Carburizing processes depend on effective exposure of the workpieces to the furnace atmosphere.

For this reason, an overly enclosed fixture structure may not be suitable for many applications.

This fixture uses an open grid and frame configuration, allowing furnace atmosphere to circulate around the loaded parts more freely.

The open structure can also reduce unnecessary fixture mass compared with a fully enclosed basket design.

FH® Alloy can optimize the opening ratio, support positions and frame arrangement according to the shape of the workpieces being treated.

Combination of 1.4852 and 310S
This fixture uses a combination of 1.4852 and 310S rather than a single material throughout the entire structure.
1.4852
1.4852 is a heat-resistant alloy material commonly used for industrial furnace fixtures and cast components operating at elevated temperatures.

For fixture applications, it can provide:

• High-temperature strength
• Good oxidation resistance
• Structural support at elevated temperatures
• Suitability for repeated furnace cycles

310S
310S is a heat-resistant austenitic stainless steel widely used for fabricated furnace components.

It offers:

• Good high-temperature oxidation resistance
• Good fabrication characteristics
• Good weldability
• Suitability for heat-resistant structural components

Using different materials in different sections allows the fixture structure to be designed according to the functional requirements of each component.

Reinforced Heat Treatment Fixture Design
Heat treatment fixtures are subjected to more than static mechanical loads.

Repeated thermal cycling can lead to:
Thermal expansion → Thermal contraction → High-temperature creep → Distortion → Fatigue
Therefore, fixture design should not focus only on increasing section thickness.

A properly designed fixture needs to balance:
Strength + Fixture Weight + Heat Transfer + Deformation Resistance + Loading Efficiency
FH® Alloy can optimize reinforcement positions, frame thickness and structural geometry according to the customer's actual operating conditions.

Suitable for Different Workpieces
This type of triangular carburizing furnace fixture can be customized for components such as gears, shafts, rings, sleeves, transmission parts, automotive components, forged parts and other precision metal components requiring controlled positioning during heat treatment.

The internal supports can be redesigned according to the shape, size and weight of the customer's workpieces.

Custom Heat Treatment Fixture Design
FH® Alloy supports manufacturing based on either customer drawings or actual furnace operating information.

Customers can provide:

1. Furnace type
2. Furnace chamber dimensions
3. Maximum operating temperature
4. Normal working temperature
5. Furnace atmosphere
6. Cooling method
7. Workpiece dimensions
8. Workpiece weight
9. Total fixture load
10. Loading arrangement
11. Existing 2D or 3D drawings
12. Photos of the current fixture

If no complete drawing is available, FH® Alloy can also develop a fixture structure according to the customer's operating conditions.

Manufacturing Process
A customized carburizing furnace fixture typically goes through several production stages:
Operating Condition Review → Material Selection → Structural Design → Casting / Material Preparation → Machining → Fabrication → Welding → Assembly → Dimensional Inspection → Final Inspection
For large fixtures such as this 1176 × 1000 × 1090 mm triangular frame assembly, controlling the overall geometry and connection accuracy between individual structural components is particularly important.

Quality Control
Before shipment, FH® Alloy can inspect critical fixture characteristics including overall dimensions, structural alignment, connection positions, weld quality, surface condition and key assembly dimensions.

For customer-specific projects, additional inspection requirements can also be discussed before production.

Other Materials Available
In addition to 1.4852 and 310S, FH® Alloy manufactures custom heat treatment fixtures using materials such as:
1.4848, 1.4849, 1.4852, 310S, Cr25Ni20, Cr25Ni35, HU, HT, HR9 and other heat-resistant or nickel-based alloys.
Material selection should be based on the complete operating environment rather than temperature alone.
