FH® 1.4849 Heat Treatment Charging Baskets for Multi-purpose Furnace

FH® 1.4849 Heat Treatment Basket | Engineered for Multi-Chamber Furnaces (Sealed Quench / Carburizing)

Key Benefits

• Genuine 1.4849 (X15CrNiSi25-21)
  Higher nickel, chromium, and silicon content than 310S – exceptional oxidation resistance and creep strength in carburizing atmospheres.
• Anti-Carburizing Design
  Optimized alloy composition reduces carbon penetration and metal dusting – maintains structural integrity through hundreds of cycles.
• Creep-Resistant Structure
  FEA-optimized rib layout and reinforced corners – minimal sagging or distortion at 950–1050°C under heavy loads.
• Thermal Shock Resistant
  Withstands repeated oil quench cycles without cracking – designed for sealed quench furnace (SQF) workflows.
• Custom Sizes & Configurations
  Single or multi-layer, stacking or nesting – designed to your furnace retort and part geometry.

Technical Specifications

Why Choose FH® 1.4849 Heat Treatment Baskets?
1. Designed for Multi-Chamber Furnace Demands
Multi-chamber furnaces (sealed quench, carburizing, carbonitriding) impose severe thermal and chemical stress – repeated heating to 950°C+, followed by oil quenching, plus aggressive carbon-rich atmospheres. FH® 1.4849 heat treatment baskets are specifically formulated and structured to survive these conditions.

2. Superior to 310S / 314

3. Weld & Cast Quality You Can Trust

• Investment casting: smooth surfaces, no sharp stress risers
• Hybrid laser-TIG welding: full penetration, minimal heat-affected zone
• 100% visual and dimensional inspection before shipment

4. Realistic, Honest Guidance
We don’t promise “forever.” We promise predictable, repeatable performance with proper maintenance – and lower cost per cycle than lower-grade alternatives.

Applications

• Sealed quench furnace (SQF)
• Batch carburizing lines
• Carbonitriding
• Protective atmosphere hardening
• Parts: gears, shafts, bearings, rings, fasteners, automotive transmission components

FAQ:

Q1: How long does an FH® 1.4849 heat treatment basket last in a carburizing multi-chamber furnace?
A: Typically 300–500 cycles with proper maintenance (regular cleaning, no overloading). This is approximately 2x the life of a 310S basket under the same conditions. Actual life depends on operating temperature, atmosphere, quench severity, and load weight.

Q2: How do I clean and maintain the heat treatment basket?
A: Light bead blasting (glass beads, ≤0.3 MPa) every 50–80 cycles to remove carbon soot and loose scale. For heavy carbon buildup, use a controlled burn-off cycle (800°C in air) followed by light blasting. Do not use carbon steel brushes or heavy grinding.

Q3: Will the heat treatment basket warp or sag at 950–1050°C?
A: Minimal. FH® 1.4849 baskets feature FEA-optimized ribs and gussets. Typical creep deformation is <3 mm per 500 mm length after 300 cycles. Overloading, exceeding 1050°C, or rapid thermal shocks outside normal quenching will accelerate warping.

Q4: Do you offer custom sizes for my specific multi-chamber furnace?
A: Yes. FH® specializes in custom baskets. Send us your furnace drawing (or we can field-measure), part photos, and cycle details. We’ll provide a CAD drawing and load simulation before production.

Q5: What is your warranty and do you provide material certificates?
A: 12 months against manufacturing defects (weld/casting cracks, material flaws). Normal surface carburization, gradual creep, and thermal fatigue are considered wear – not covered. Every basket comes with a 1.4849 mill test certificate (MTC).
