Stainless-Steel Alloys

Stainless steels suitable for medical device manufacturing are available from Tempered and Specialty Metals, Sterling Heights, MI. For medical devices, 304 is used where high corrosion resistance, good formability, strength, manufacturing precision, reliability, and hygiene are of particular importance. For surgical stainless steel, 316 and 316L are predominantly used. By alloying the elements chromium, nickel, and molybdenum, stainless steel offers a uniquely reliable product for scientists and surgeons. When surgical blades are called upon for heavier duty cutting or oscillating action, the company's in-house tempering can produce light gauges at various tempers up to full hard.
