Stainless Steel – Grade 316

Stainless Steel – Grade 316

316 Stainless Steel is commonly used for food processing equipment, and as surgical stainless steel. 316 is also know as marine grade stainless steel due to its higher resistance to chloride corrosion compared to type 304.

316L is an extra low carbon grade of 316, often found 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, a typical application would be flexible chimney liners.

316 stainless steel is a molybdenum-bearing grade. This addition gives the better overall corrosion resistance properties than type 304and higher creep strength at elevated temperatures.

All stainless stock can be delivered mirror polished if required, Call for details.
