316L is a high quality stainless steel with good welding characteristics and relatively low magnetic permeability. It also has a greater resistance to corrosive gases such as chlorine than 304 stainless steel. For this reason it is the preferred option for Semiconductor Production applications. This flange comes with 8 size M8 bolt holes
