How do you identify the type of stainless steel used on a stainless steel thermos flask? Today we would like to introduce a simple method.
As you know, the most conventional types of stainless steel used in the stainless steel insulated flask industry are 201 stainless steel and 304 stainless steel.
304 stainless steel is a food grade material and can pass FDA, LFGB testing. They are commonly used as the inner liner of stainless steel insulated bottles and will not rust. Whereas 201 stainless steel is prone to rusting. So 304 stainless steel is safer to use as the liner of an insulated mug.
How can I identify stainless steel models such as 304 and 201? We would recommend a special chemical reagent for testing stainless steel materials. ---- Manganese content testing reagent.
It is well known that all 200 series stainless steels contain the element Mn. For example, 201 stainless steel has a Mn content of 6%, while 304 stainless steel has almost zero Mn. With this reagent we can identify whether the stainless steel material contains Mn and then we can tell whether it is 304 or 201s/s.
Simply place a drop of the identification solution on the surface of the stainless steel and see if the solution turns red.
200 stainless steel: 2 seconds to red, 10 seconds to brown, manganese exceeds the limit.
201&202 stainless steel: turns red in about 35-40 seconds, manganese exceeds the limit.
301 stainless steel: turns light red in about 50 seconds.
304 & 316 stainless steel: does not turn red for 1 minute.

Please refer to the chromatographic bars in the standard chart below to confirm the type of stainless steel. The faster the change, the lower the quality of the material!
