SUS304

Features

  • Made of the cheapest material used most widely among the various types of stainless steel。

Application examples

  • Toasters and show cases。
  • etc。

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。

Material specifications

  • Available diameter : ø0.52 ~ ø16.00
  • Details of contents : Ni 8.0~10.5, Cr 18.0~20.0, Mn 2.00MAX, Fe Bal
  • Proper environment : Air heating
  • Limit service temperature(UL) : 600°C or less

SUS321

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。
  • etc。

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。

Material specifications

  • Available diameter : ø0.52 ~ ø16.00
  • Details of contents : Ni 9.0~13.0, Cr 17.0~19.0, Ti 5*C% MAX, Mn  2.00MAX, Fe Bal
  • Proper environment : Air heating
  • Limit service temperature(UL) : 650°C or less

SUS316L

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。
  • etc。

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。

Material specifications

  • Available diameter : ø0.52 ~ ø16.00
