Features
- Used very widely for burn-in-air heating in Japan.
- Has relatively high resistance against moist environments. Recommended for users who do not need very high corrosion resistance.
Application examples
Fish roasters, microwave oven ranges, hot plates, can vending machine, and heat accumulating heaters
Precautions
- These heaters are prone to creat scale on pipe surfaces, depending on the use environments.
- High-nickel steel is hard material, and the user should pay attention to the bending radius.
The bending radius standards also depend on the bending shapes such as U, L, etc.

Features
- Contains the same quantity of nickel and chromium as Incoloy 840.
- Contains 2% molybdenum and features superior corrosion resistance.
- Recommended for applications at high temperature in salt-containing environments.
- Can be acid-washed or electrolytic-polished as surface processing when used for in-water heating only.
Application examples
Fish roasters, small calorifiers, hot plates, cup vending machines and tea dispensers
Precautions
- NAR-AH-1 is hard material, and the user should pay attention to the bending radius.
The bending radius standards also depend on the bending shapes such as U, L, etc.
