Today we will discuss the difference between 304 stainless steel and 316 stainless steel.

2. The difference of corrosion resistance.
The difference between stainless steel pressure drums can be seen from the degree of corrosion resistance. Usually 304 stainless steel and 316 stainless steel have almost no difference in chemical resistance, but they are different in some media. The previously shared "304 relationship with other stainless steel materials" clearly shows the difference between stainless steel pressure barrels and some relationships. When the original 304 stainless steel was developed, the material was sensitive to spot corrosion in some cases. To reduce these sensitivities, an additional 3% molybdenum was added to produce 316 stainless steel. These extra molybdenum can also reduce the corrosion of some thermoorganic acids. In all types of water quality (distilled water, drinking water, River water, boiler water, etc.), 304 stainless steel and 316 stainless steel have almost the same corrosion resistance, but when the chloride ion content in the medium is very high, 316 stainless steel is more suitable for stainless steel pressure barrel material. Specific analysis of the specific situation.
