Features
- Made of the cheapest material used most widely among the various types of stainless steel.
Application examples
Toasters and show cases
Precautions
- May be subject to rust depending on the use environments, though these heaters are made of stainless steel.
- Do not use them in environments that are always moist.
- Stainless steel is a 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 more nickel than SUS304 and also contains titanium. Features higher heat and corrosion resistance.
Application examples
Fish roasters, can dispensers, microwave oven ranges, toasters, show cases and defrosters
Precautions
- These heaters are prone to creat scale on pipe surfaces, depending on the use environments.
- SUS321 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.

Heating in water
Air heating
|
600°C or less

Features
- Contains much nickel and chromium. Also contains molybdenum. Features superior corrosion resistance.
- Mainly used in water or humid environments. Recommended material exclusively used for heating in water.
- Requires electrolytic polishing, passivation processing or acid washing, which is indispensable for use in water.
Application examples
Fryers, electric kettles, show cases, defrosters, and calorifiers
Precautions
- SUS316L 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.
