316 stainless steel, also known as UNS S31600, is a popular and widely used austenitic stainless steel alloy. It is part of the 300 series of stainless steels, which are characterized by their high levels of corrosion resistance and excellent mechanical properties. Grade 316 stainless steel is known for its superior resistance to corrosion, making it highly suitable for a wide range of applications, particularly in aggressive and corrosive environments.
