FH® 310s Welded Heat Treatment Baskets
FH® Welded Heat Treatment Baskets | Precision-Engineered for Furnace Applications
Key Benefits
- Precision Welding Technology
Hybrid laser + TIG welding process – minimal heat-affected zone, full penetration, and spatter-free seams. - No Weld Drop or Spatter
Clean welding process eliminates loose weld beads or spatter that can fall onto parts during processing. - Thermal Fatigue Resistant
Stress-relieved construction and optimized weld geometry resist cracking through hundreds of heating and cooling cycles. - Stronger Than Cast
Welded structures offer higher tensile strength and better impact resistance than cast alternatives – ideal for heavy loads. - Fully Customizable
Any size, shape, or configuration – trays, baskets, grids, racks, and part-specific designs.

Why Choose FH® Welded Baskets?
1. Precision Welding – The FH® Difference
| Feature | FH® Welded Basket | Typical Competitor |
| Weld spatter | None – laser/TIG | Present – stick/MIG |
| Weld consistency | Uniform, full penetration | Variable, shallow penetration |
| Heat-affected zone | Minimal | Large – risk of sensitization |
| Post-weld cleaning | Not required | Grinding needed – creates stress risers |
| Thermal fatigue life | 2-3X longer | Baseline |
2. Clean Operation – No Part Contamination
Weld spatter, loose beads, or rough grinding marks can detach during furnace cycling and fall onto your parts. FH® laser/TIG welding produces clean, smooth seams that remain intact through hundreds of cycles.
3. Material Selection Guide
| Material | Max Temp | Best For |
| 310S | 950°C | General hardening, carburizing |
| 1.4828 | 1000°C | Higher temperature annealing |
| 1.4849 | 1100°C | Heavy loads, long cycles, aggressive atmospheres |
| Ni-base alloys | 1250°C | Extreme temperatures |
Basket Types Available

FAQ:
Q1: Why choose welded baskets over cast?
A: Welded baskets offer higher strength, faster lead time (no patterns), easier repair, no porosity, and lower cost for small quantities. Cast is better for very complex geometries or high-volume runs.
Q2: How long will an FH® welded basket last?
A: Carbon steel (≤450°C): 100–200 cycles; 310S (≤950°C): 200–350 cycles; 1.4849 (≤1050°C): 400–600 cycles. Regular cleaning extends life.
Q3: Will weld spatter fall onto my parts?
A: No. FH® laser/TIG welding produces zero spatter. Seams are smooth and fully fused – no post-weld grinding needed.
Q4: Can you repair my existing welded basket?
A: Yes – re-weld cracked joints or replace damaged sections. Severely warped or carburized baskets are typically not repairable. Send photos for assessment.
Q5: What is your warranty?
A: 12 months against manufacturing defects (weld cracks, material flaws). Normal wear, creep, and thermal fatigue are not covered.
