316 Stainless Steel - used for food and surgical stainless
steel. Also known as marine grade stainless steel due to its increased
resistance to chloride corrosion compared to type 304. 316L is an extra
low carbon grade of 316, generally used in stainless steel watches. Its
resistance to chloride attack means it is often selected for use in
marine atmospheres. 316Ti includes titanium for heat resistance,
therefore it is used in flexible chimney liners.
316 stainless
steel is a molybdenum-bearing grade. This addition gives the better
overall corrosion resistance properties than type 304 and higher creep
strength at elevated temperatures.
