Precision-manufactured heat-resistant steel sliders for industrial furnaces, heat treatment lines, kiln cars, and high-temperature conveying systems. Custom alloys | OEM manufacturing | Global supply capability

Product Overview

FH® Heat-Resistant Steel Sliders are precision-engineered components designed for high-temperature sliding applications in industrial environments. Manufactured using centrifugal casting, precision forging, or CNC machining — depending on application requirements — these sliders provide reliable performance under thermal cycling, heavy loads, and oxidative conditions.

Each slider is produced from certified heat-resistant alloys with guaranteed chromium (Cr) and nickel (Ni) content. FH® maintains strict dimensional tolerances to ensure proper fit and smooth movement across the full operating temperature range.

Typical Applications

• Industrial furnace support structures
• Heat treatment conveyor systems
• Kiln car sliding mechanisms
• Continuous casting guide rails
• High-temperature pipe supports
• Glass furnace feeder plates

FAQ:

Q1: What is the maximum operating temperature for FH® heat-resistant steel sliders?
A: Continuous service temperature depends on the selected alloy — up to 1150°C for 310S grade, with custom alloys available for applications up to 1200°C+. Peak temperatures during startup or transient conditions can be higher; consult our engineering team for specific requirements.

Q2: How do FH® sliders perform under thermal cycling?
A: FH® sliders are designed with thermal expansion considerations. Austenitic stainless steels maintain stable expansion coefficients across the temperature range, and our machining tolerances account for operational clearance. We recommend specifying thermal cycle conditions during the design phase for optimal performance.

Q3: What documentation is provided with each order?
A: Standard shipments include a Material Test Report (MTR) and Certificate of Compliance. Additional documentation — including third-party inspection reports, NDT results, or project-specific certifications — can be provided upon request.

Q4: What is the minimum order quantity (MOQ)?
A: FH® supports both prototype quantities and full production runs. For standard sizes, there is no MOQ. For custom castings or custom tooling, we work with customers to accommodate their project requirements.

Q5: How long is the warranty?
A: FH® provides a 12-month warranty against manufacturing defects from the date of shipment. Extended warranties may be available for specific applications or high-volume agreements.

Q6: Do you provide installation support?
A: Yes, FH® offers technical support for installation and alignment. For large projects, on-site support can be arranged. Our engineering team is available for consultation throughout the project lifecycle.
