The Material Of The Tubular Heater Of Steamer
Now the mainstream steam oven tubular heater material on the market is stainless steel. Mainly 301s stainless steel and 840 stainless steel.
The stainless steel tubular heater heats the fluid by forced convection.
Advantages: corrosion resistance, not easy to rust, good heat resistance, safety, strong plasticity
The difference between the quality of the stainless steel electric tubular heater is mainly the nickel content. Nickel is an excellent corrosion-resistant material. After being combined with chromium in stainless steel, the corrosion resistance and process performance of stainless steel can be improved to some extent. Both 310S and 840 stainless steel tubes contain 20% nickel, which is an excellent material for tubular heaters that has strong acid and alkali resistance and high temperature resistance.
In fact, 301s stainless steel is more suitable for steaming ovens than 840 stainless steel. It has stronger corrosion resistance. You don't have to worry about being perforated and rusted by steam rust after soaking in water for a long time. It is the most suitable for steaming ovens.
Some manufacturers use 840 stainless steel, and then deceive consumers under the banner of "medical grade" and "professional oven baking tube". Indeed, 840 stainless steel is used in professional ovens, but the oven is not equal to the steaming oven, and the concept cannot be changed. The 840 stainless steel tubular heater used in the steaming oven mentioned here is easily corroded by steam.
