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.

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.
