Why use 316 instead of 304 standard stainless steel?

Grade 316 has a better resistance to chemicals and chlorides (like salt) than grade 304 stainless steel. When it comes to applications with chlorinated solutions or exposure to salt, grade 316 stainless steel is considered superior. Which makes it a good choice for high-saline environments (i.e., coastal regions and areas where de-icing is used) and industrial applications involving chemical processes. Grade 316 stainless steel is ideal for medical applications where high tensile strength is required or that involve regular exposure to corrosive elements like chemicals, water, or bodily fluids. The difference between 304 and 316 stainless steel is that 316 contains molybdenum, which enhances corrosion resistance, while 304 does not.
