Custom 1.4849 Heat Treatment Baskets and Base Tray for Serbian Customer | FH® Alloy

Custom 1.4849 Base Tray and Heat Treatment Baskets for a Serbian Customer
Customer Case Study | Engineering Design, Manufacturing, Final Inspection & Delivery
Customer Location: Serbia
Product: Custom Base Tray & Heat Treatment Baskets
Material: 1.4849 Heat-Resistant Stainless Steel
Application: Vacuum Furnace & Atmosphere Furnace Heat Treatment
Project Scope: Design → 3D Modeling → Manufacturing → Final Inspection → Delivery
Manufacturer: Wuxi Junteng Fanghu Alloy Technology Co., Ltd. (FH® Alloy)

Project Overview
FH® Alloy received an inquiry from a customer in Serbia for a set of customized heat treatment baskets and a base tray.

The customer required:

• 1 type of base tray
• 2 different basket sizes
• all manufactured in 1.4849 heat-resistant stainless steel

The project involved furnace tooling for demanding heat treatment applications, including:

• vacuum furnace service up to 1250°C with nitrogen cooling
• Ipsen TQ-4 atmosphere furnace service at 1050°C with oil cooling

Based on the customer's application requirements and requested sizes, FH® Alloy completed the engineering design and final 3D models for all three products, then proceeded with manufacturing, final inspection and delivery.

Customer Requirements
The Serbian customer requested the following products:

The final designed 3D models correspond to:

• Image 1: Basket, 870 × 555 × 134 mm
• Image 2: Basket, 870 × 550 × 254 mm
• Image 3: Base Tray, 900 × 600 × 45 mm

Operating Conditions
The customer provided furnace application information for the project.

Vacuum Furnace Condition

• Maximum temperature: 1250°C
• Cooling medium: Nitrogen (N2)

Atmosphere Furnace Condition

• Furnace type: Ipsen TQ-4
• Working temperature: 1050°C
• Cooling medium: Oil

These operating conditions required the tooling to offer reliable structural stability and suitability for repeated thermal cycles.

Engineering Challenge
This project was more than producing standard furnace tooling.
FH® Alloy needed to design a coordinated set of components that would match the customer’s process conditions and dimensional requirements.

The engineering challenge included:
1. Multiple Product Types in One Project
The project included one base tray and two different basket sizes, each with different structural needs.
2. High-Temperature Service
The products needed to be suitable for demanding furnace conditions, including service temperatures up to 1250°C.
3. Different Cooling Media
The tooling needed to be appropriate for both nitrogen cooling and oil cooling conditions.
4. Structural Stability and Practical Use
The baskets and tray needed to provide stable support, practical handling and suitability for repeated industrial use.

FH® Alloy Design Solution
Based on the customer’s requirements, FH® Alloy developed the final 3D models for all three customized products.

Product 1: Basket 870 × 555 × 134 mm
The first basket design features a reinforced open-grid base combined with a surrounding side frame and internal support posts.

Key design features:

• open structure for good furnace atmosphere circulation
• reinforced side walls for structural stability
• internal support/positioning posts
• practical basket depth for loading applications

This design provides a good balance between load support, heat flow and handling convenience.

Product 2: Basket 870 × 550 × 254 mm
The second basket design is a taller basket version with a deeper structure.
Compared with the smaller basket, this version provides greater loading height while maintaining a strong surrounding frame and base support system.

Key design features:

• higher basket structure for increased loading space
• reinforced frame geometry
• integrated support posts
• stable design for repeated furnace use

This basket was designed to fit the customer’s required dimensions while maintaining good structural integrity.

Product 3: Base Tray 900 × 600 × 45 mm
The third product is a customized base tray.
The base tray adopts a compact open-cell structure that supports heat treatment use while keeping the geometry practical and stable.

Key design features:

• open structural layout
• good support distribution
• practical tray thickness and rigidity
• suitable for repeated high-temperature service

This tray complements the basket project and demonstrates FH® Alloy’s ability to provide a complete customized tooling solution.

Why 1.4849 Was Used
All three products were designed in 1.4849 heat-resistant stainless steel.

For furnace tooling applications, 1.4849 is widely used because it offers:

• good high-temperature strength
• oxidation resistance
• thermal stability
• suitability for repeated heating cycles

For FH® Alloy, material selection is always considered together with structural design.
A suitable high-temperature alloy must be matched with a rational basket or tray structure to achieve stable service performance.

Manufacturing
After approval of the final designs, FH® Alloy proceeded with production of:

• 4 pcs base trays
• 5 pcs baskets (870 × 555 × 134 mm)
• 5 pcs baskets (870 × 550 × 254 mm)

Production was carried out according to the approved engineering models, with attention to:

• dimensional accuracy
• structural consistency
• product geometry
• manufacturing quality

Final Quality Inspection
Before shipment, FH® Alloy carried out final inspection of the completed products.

The inspection included:
Dimensional Inspection
Checking whether the finished baskets and trays matched the approved sizes.
Structural Inspection
Reviewing the frame structure, support areas and overall manufacturing condition.
Drawing Conformity Check
Ensuring that the final products matched the approved 3D designs.
Shipment Preparation
After passing inspection, the products were prepared for final delivery to the customer.
