What is the main difference between stainless steel 304 and 316? What is the advantage in having SS316 kitchen hood?

304 stainless steel is versatile and wide ranging. It serves a variety of industrial, architectural, consumer, and transportation applications. It offers a high level of resistance to corrosion but will eventually show signs of tarnish over time.304’s composition provides a better structural advantage and durability than other grades of stainless steel. For manufacturing purposes it’s customizable and easy to fabricate; making it the most widely used commercial stainless steel today.

------------------------------------------

316 stainless steel has molybdenum added to its alloy content during production. Molybdenum provides an even higher degree of corrosion resistance than304 stainless steel. This is an advantage for objects that require resistance to extreme environmental conditions such as salt water, de-icing salts, brine solutions, or other chemical forms of chemical exposure. In laboratory and pharmaceutical settings,316 stainless steel excels in resistance to acids, bromides, and iodides at high temperature.

Sir as per my understanding it increases the corrision resistance of the duct.
