Project Overview
FH® Alloy was contracted by Sars, a heat treatment customer from Turkey, to manufacture customized 1.4848 heat treatment fixtures for turbine blade processing.

The fixture was designed according to the customer's specific loading requirements and heat treatment process conditions. With a size of 1220 × 910 × 50 mm, the fixture needed to maintain structural stability during repeated high-temperature cycles while ensuring accurate positioning of turbine blade components.

Through optimized material selection and precision manufacturing, FH® Alloy provided a reliable heat treatment tooling solution suitable for demanding aerospace-related applications.

Customer Requirements
For turbine blade heat treatment applications, the fixture must withstand repeated exposure to high temperatures while maintaining dimensional accuracy.
The customer's key requirements included:

High Temperature Performance
The fixture needed to operate under high-temperature heat treatment conditions with excellent resistance to:

• Thermal deformation
• Oxidation
• High-temperature fatigue

Stable Structure During Thermal Cycling
During repeated heating and cooling cycles, the fixture needed to maintain:

• Flatness
• Dimensional stability
• Mechanical strength

Customized Dimensions
The customer required a special fixture size:
Overall Dimension:
1220 × 910 × 50 mm
The design needed to match the customer's furnace space and turbine blade loading method.

Material Selection: 1.4848 Heat Resistant Steel
Based on the working environment and application requirements, FH® Alloy selected 1.4848 heat resistant steel for this heat treatment fixture.
