AISI 304 and 316 stainless steel appear the same but perform very differently depending on the surrounding environment . This is Due to the differences in the chemical composition between the two grades with AISI 316 offering more resistance to corrosion due to the molybdenum content .
In line with industry guidelines , as a general rule we recommend AISI 316 for outdoor use and AISI 304 for interior projects .
