1.4849 Stackable Heat Treatment Basket | 1170 × 618 × 265 mm

Product Specification

Custom Heat Treatment Basket for Industrial Furnace Applications
FH® Alloy manufactures custom heat treatment baskets and furnace fixtures for industrial heat treatment applications.

This stackable heat treatment basket is manufactured from 1.4849 heat-resistant alloy steel and has an overall size of 1170 × 618 × 265 mm.

The basket combines a rigid heat-resistant frame with an open metal mesh structure, providing support for loaded components while allowing furnace atmosphere and cooling media to circulate around the workpieces.

Its stackable design allows multiple baskets to be assembled vertically, helping increase furnace loading efficiency while maintaining organized separation between individual layers.

Dimensions, material, mesh size, frame structure and stacking configuration can all be customized according to the customer's furnace and heat treatment process.

Product Specifications

1.4849 Heat-Resistant Alloy Construction
Material selection is one of the most important factors affecting the service life of heat treatment fixtures.
1.4849 is a heat-resistant Cr-Ni alloy steel commonly used for furnace fixtures and components that operate under elevated temperatures.

For heat treatment basket applications, the material provides a combination of:

• Good high-temperature strength
• Good oxidation resistance
• Good dimensional stability
• Resistance to repeated heating and cooling cycles
• Suitability for industrial furnace environments
• Good performance for fabricated and cast heat treatment fixtures

The final material selection should always be based on the actual operating temperature, atmosphere, cooling method, loading weight and thermal cycle.

Stackable Basket Design
One of the key features of this basket is its stackable structure.
The upper and lower sections are designed so that multiple baskets can be stacked in a stable arrangement during loading, transportation and furnace operation.

This design offers several practical advantages:

• Increased furnace loading capacity
• Better use of vertical furnace space
• Easier separation of workpieces by layer
• More organized loading and unloading
• Improved handling efficiency
• Flexible adjustment of total loading height

For different furnace configurations, FH® Alloy can customize the stacking points, locating structure, side supports and lifting positions.

Open Mesh Structure for Furnace Circulation
The side walls use an open metal mesh rather than a fully enclosed plate structure.
This design helps furnace atmosphere or cooling media circulate through the basket and around the loaded parts.

Depending on the heat treatment process, the open structure can help support:

• More uniform heating
• Improved furnace atmosphere exposure
• Faster gas circulation
• More effective cooling
• Reduced unnecessary fixture mass

The wire diameter and mesh opening can be customized according to the size and weight of the customer's components.

Reinforced Frame for Industrial Loading
Heat treatment baskets experience more than just static loading.
During actual production, the fixture may also be affected by:

• High-temperature creep
• Thermal expansion and contraction
• Repeated heating cycles
• Lifting and transfer forces
• Component loading
• Stacking forces

For this reason, the basket uses a reinforced frame around the mesh structure.
The outer frame helps maintain the basket geometry while the internal and side reinforcement sections provide additional support for repeated industrial operation.

Designed for Repeated Heat Treatment Cycles
Heat treatment fixtures are consumable production tooling, and their service life depends strongly on the operating conditions.
A well-designed basket should balance:
Strength + Fixture Weight + Heat Flow + Loading Capacity + Thermal Expansion
Simply increasing the thickness of every section does not necessarily produce the best fixture.
FH® Alloy can optimize the frame structure according to the customer's actual furnace conditions to reduce unnecessary material while maintaining sufficient structural support.

Typical Applications
This type of 1.4849 stackable heat treatment basket can be customized for processing components such as:

• Gears
• Shafts
• Bearings
• Rings
• Fasteners
• Automotive components
• Transmission parts
• Mechanical components
• Forged parts
• Precision metal components

It can be designed for use in various industrial heat treatment processes and furnace systems.

Suitable Furnace Applications
Custom versions of this basket can be manufactured for:

• Atmosphere furnaces
• Batch furnaces
• Carburizing furnaces
• Annealing furnaces
• Hardening furnaces
• Tempering furnaces
• Continuous furnaces
• Pit furnaces
• Gas quenching systems
• Other industrial heat treatment furnaces

Because operating conditions vary considerably between furnaces, FH® Alloy recommends selecting the fixture design according to the actual furnace and process, rather than using one universal basket design.

Fully Customizable Heat Treatment Basket
FH® Alloy supports OEM and custom manufacturing.
Customers can provide an existing drawing, sample or only their furnace operating information.

We can customize:

• Basket length
• Basket width
• Basket height
• Alloy grade
• Mesh opening
• Wire diameter
• Frame thickness
• Reinforcement structure
• Stacking configuration
• Lifting points
• Locating structure
• Loading arrangement

For replacement projects, customers can also provide photos of previously used or deformed baskets for evaluation.

Manufacturing Process
A custom heat treatment basket typically goes through several manufacturing stages:
Material Selection → Pattern / Casting Preparation → Casting → Machining → Mesh Fabrication → Assembly → Welding → Dimensional Inspection → Final Inspection
For stackable baskets, dimensional consistency is especially important because the upper and lower locating structures must match properly when multiple baskets are assembled.

Quality Control
Before shipment, critical points can be inspected according to the customer's specifications, including:

• Overall dimensions
• Frame geometry
• Stacking fit
• Weld quality
• Mesh installation
• Surface condition
• Key locating dimensions

Additional inspection requirements can also be discussed according to the project.

Other Materials Available
In addition to 1.4849, FH® Alloy can manufacture heat treatment baskets and furnace fixtures from various heat-resistant materials, including:

• 1.4848
• 1.4849
• 1.4852
• 310S
• Cr25Ni20
• Cr25Ni35
• HR9
• HU
• HT
• Nickel-based heat-resistant alloys
• Other materials according to customer specifications

The most suitable material should be selected according to the actual combination of temperature, atmosphere, cooling method and mechanical load.
