What are the differences between bimetallic thermometer stainless steel shell material?

Bimetallic thermometer is often used in industrial equipment, petrochemical industry, heating systems, hvac equipment, pipeline and ventilation equipment, power plants and Marine, etc. , therefore, the material of manufacture bimetallic thermometer basically is given priority to with stainless steel, and stainless steel also can be divided into two kinds of SS304 and SS316, then choose what is the difference between the two different material? Today let's bimetallic thermometer, for example, say what is the difference between bimetallic thermometer stainless steel material. Model: A300C - 1 ( WSS3B825150) Type: hot shell bimetallic thermometer structure: universal type cover circle: flange type, tray type panel material: stainless steel SS304 tooth head: 1/2 & quot; NPT other optional surface diameter: 80 mm heat pipe diameter: 6. 35 mm heat pipe length: 150 mm ( 50 - Optional) around 2000 mm. Temperature range: 0 - 150 c F ( Can be customized) Accuracy: & plusmn; 1. Table: 5% glass protection grade: IP65 ( Dust, water) This is a common type of universal bimetallic thermometer, according to the specification, we can see that it is SS304 material, in fact SS304 and SS316 is stainless steel, the biggest difference between them is SS316 stainless steel corrosion resistance is superior to the SS304 stainless steel, so we can according to the practical use of the environment to choose the appropriate materials.
