STAINLESS STEEL 316L,321

SUS304， SUS321， SUS316L ， SUS309S， SUS310S

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。

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。
