About FeCrAl Heating Coil

Heanjia Super Metals Co., Ltd. is produce the highest quality FeCrAl Heating coils and Kanthal Coil Substitute in China by using dual electroslag smelting technical route: three-phase lined furnace + electroslag remelting. This offers advantages such as high purity, good uniformity, and long material service life. Other companies in the same industry use medium-frequency furnace smelting, which our company phased out long ago. Their process uses a large amount of scrap steel, resulting in relatively lower costs but higher content of harmful impurities, high compositional segregation and non-uniformity, unstable and fluctuating material properties, susceptibility to local melting during use, and short service life cycles.

Heanjia supplies several grades of FeCrAl heating coil and Kanthal Coil Substitute for different applications:

For application temperatures up to 1300℃： 0Cr23Al5 and 0Cr25Al5

For application temperatures up to 1350℃：0Cr21Al6Nb

For application temperatures up to 1400℃： HJ209 (Kanthal A1 Coil substitute)

For application temperatures up to 1425℃： HJ407 (Kanthal APM Coil substitute)

 Comparison of Heating Coil Grades:

Alloy Grade Cr % Al % Nb % Max Temp (°C) Key Advantage Price
0Cr23Al5 23% 5% — 1300°C Standard industrial grade $8/kg-$20/kg
0Cr25Al5 25% 5% – 1300°C Higher Cr for corrosion resistance $8/kg-$20/kg
0Cr21Al6Nb 21% 6% 0.5-1% 1350°C Best oxidation + creep resistance $18/kg-$28/kg
HJ209(Kanthal A-1 Substitute) 22% 5.8% – 1400°C Premium industrial grade $20/kg-$30/kg
HJ407(Kanthal APM Substitute) 21% 5% 0.02% Ce 1425°C Rare-earth enhanced $28/kg-$50/kg

Applications of FeCrAl Heating Coils and Kanthal Coils:

  1. Industrial Heating

   – Electric furnaces (for metals, ceramics, glass) 

   – Heat treatment (annealing, tempering, sintering) 

   – Industrial ovens & kilns 

  1. Consumer Appliances

   – Toasters, hair dryers, space heaters 

   – Electric stoves & ovens 

  1. Laboratory Equipment

   – High-temperature lab furnaces 

   – Thermal analysis instruments 

  1. Automotive & Aerospace

   – Glow plugs (diesel engines) 

   – Aircraft de-icing systems 

Best for: 

✔ High-temp oxidizing environments (air, oxygen-rich) 

✔ Long-duration heating (industrial furnaces) 

Avoid in: 

❌ Reducing atmospheres (H₂, CO) → Use NiCr instead 

❌ Sulfur-rich environments → Can cause sulfidation 

How to Select a FeCrAl Heating Coil?

  1. Determine (continuous)Operating Temperature

   – <1250°C →0Cr23Al5 or 0Cr25Al5

   – <1300°C → Premium FeCrAl e.g., 0Cr21Al6Nb,  HJ209(Kanthal A-1 Substitute)

   – >1350°C → High-grade e.g., HJ407(Kanthal APM Substitute)
