What is the typical usage of type 304 stainless steel vs. type 316 stainless steel?

Answer 1

304 when you need to machine it.

316 when you need something harder than 304 or better corrosion resistance.

quote ""Type 304 is also used for the dye tanks, pipelines buckets, dippers, etc. that come in contact with the lormic, acetic, and other organic acids used in the dyeing industry. ""

"" Type 316 is the main stainless used in the marine environment, with the exception of fasteners and other items where strength and wear resistance are needed, then Type 304 (18-8) is typically used. ""
