20+ Years Casting Experience – Professional Manufacturer of Heat Resistant Steel

Product Specification

Engineered for high-temperature furnaces, heat treatment equipment, and thermoforming machinery. Designed to withstand thermal expansion, reduce wear, and eliminate seizing — ensuring long-term reliability.

Product Overview:
FH® Heat-Resistant Steel Sliders are manufactured from high-grade heat-resistant alloys such as ZG40Cr25Ni20Si2, 1Cr18Ni9Ti, and 310S/2520 stainless steel. Produced through precision casting or forging, these components are widely used in high-temperature conveying systems and sliding support structures across metallurgical, glass, ceramic, and heat treatment industries.

Key Features

• Exceptional Heat Resistance: Continuous operation from 800°C to 1200°C; capable of withstanding peak temperatures beyond standard limits
• Oxidation & Creep Resistance: Advanced alloy composition forms a protective oxide layer to resist scaling and maintain structural integrity
• Precision Sliding: Tight tolerance control ensures smooth, consistent movement even under thermal expansion
• Extended Service Life: Superior wear resistance reduces maintenance frequency and minimizes unplanned downtime

Material Options:

FAQ:

Q1: How does FH® address thermal expansion issues?
A: All metals expand under high temperatures. FH® slide blocks are designed with appropriate clearance tolerances and use austenitic stainless steels with stable thermal expansion coefficients to prevent binding or seizing across the full temperature range.

Q2: Is surface oxidation a concern?
A: No. Under high temperatures, heat-resistant steel forms a dense Cr₂O₃ or NiO oxide layer that acts as a natural barrier against further oxidation. FH® alloys are formulated to enhance oxide layer adhesion and minimize spalling.

Q3: How do I select the right material?
A: For operating temperatures below 800°C without corrosion, [Cr25Ni20] is suitable. For temperatures above 1000°C with oxidation concerns, FH® recommends 310S / 2520 grade. Contact our technical sales team for selection assistance.

Q4: Does FH® accept small batch or custom orders?
A: Yes. FH® supports both prototype sampling and production-scale orders. Custom configurations are welcome — please provide drawings or specifications.
