Direct answer: Heat-resistant alloy cast parts are selected from the component geometry, furnace conditions, load, operating cycle and failure evidence rather than from a material name alone. ECOOSUN can review a drawing or used sample and align casting and inspection requirements with the project.
Material selection for a furnace component is a service-condition decision. The alloy name is important, but it is only one part of the review. Furnace atmosphere, temperature, load, section geometry, thermal cycling, support and expected maintenance interval all matter.
Material options for discussion
ECOOSUN can discuss the following heat-resistant grades for its custom furnace components, subject to application review:
| Grade | Common designation | Approximate long-term working temperature supplied for initial discussion |
|---|---|---|
| EN 1.4852 | 25Cr-35Ni-Nb | About 1100–1150°C |
| EN 1.4851 | X15CrNiSi25-21 | About 900–1000°C |
| EN 1.4845 | 25Cr-20Ni | About 900–1000°C |
| EN 1.4857 | 25Cr-35Ni / HP40 | About 1050–1150°C |
| HU | ZG45Ni38Cr18Si2 | About 1093°C |
These figures are indicative ranges for preliminary communication, not a guarantee for every geometry or furnace. The final recommendation should be confirmed against the complete operating condition.
Which product is being designed?
For Heat Treatment Baskets and Heat Treatment Trays, the review often centers on batch weight, support structure, openings, thermal cycling and handling. For Heat Treatment Fixtures, workpiece contact, locating features and process exposure are important. For Radiant Tubes and Furnace Rolls, geometry, thermal gradients, connections, load and alignment also become central.
What should be included in the material RFQ?
Send the workpiece or furnace drawing, temperature and atmosphere, load, cycle information, failure history and preferred inspection scope. ECOOSUN can discuss chemical composition verification, dimensional inspection, hardness testing and non-destructive testing when required.
ECOOSUN is an overseas brand with more than 20 years of casting experience. Request a preliminary material and product review through Contact Us or WhatsApp.
Production context: The component reference should be read together with the manufacturing and inspection context behind the furnace application.
FAQ
What should a buyer confirm for a heat-resistant alloy part requirement?
Confirm the drawing or used sample, key dimensions and interfaces, furnace type and clearance, load, operating cycle, failure evidence and inspection requirements. Final acceptance criteria should be agreed for the specific project.
Can ECOOSUN review a custom heat-resistant alloy part requirement?
Yes. ECOOSUN can review a customer drawing or used sample and discuss casting, laboratory and inspection requirements for a custom furnace-component project. Suitability and final scope are confirmed from the supplied information.
