Stainless Steel Alloy AISI 422, also known as Alloy 616, is part of the martensitic family of stainless steels and is formulated for use in aircraft and power industries that require high strength/weight ratios from room temperature to 1200°F. This material has the highest electrical conductivity among wrought martensitic stainless steels, has a moderately high embodied energy and a moderately high base cost.
