Heat-Resistant Steel Casting Heat Treatment Fixture with ZG40Cr25Ni20 Material and 1150°C Max Service Temperature via Investment Casting

Using premium grades such as ZG40Cr25Ni20, 310S, and 2520 through investment casting or centrifugal casting processes.

These materials offer excellent high-temperature strength and creep resistance, with a continuous service temperature up to 1150°C, making them ideal for carburizing, nitriding, annealing, and other heat treatment lines.

Compared to ordinary cast iron or carbon steel fixtures, our heat-resistant steel castings last 3-5 times longer, significantly reducing your downtime for replacement.

• Heat Treatment Tray
• Basket
• Furnace Roller
• Radiant Tube
• Fixture Hanger

The castings feature smooth, crack-free surfaces with dimensional accuracy up to CT7-9 grade, supporting heavy loads from tens to hundreds of kilograms without deformation or spalling at high temperatures.

1. You provide furnace drawings or fixture operating conditions (temperature, load, atmosphere).
2. Our engineering team performs CAE simulation to optimize rib structure and wall thickness.
3. We produce wood or metal molds, supporting rapid sampling (first article in 30-45 days).
4. After mass production, we provide material certificates and dimensional inspection reports.

By choosing us, you receive a one-stop solution for heat-resistant steel fixtures, from material selection and casting process design to precision machining and after-sales replacement guidance. We are committed to offering competitive pricing and on-time delivery, helping your heat treatment line run efficiently.
