Nitronic 60
Nitronic 60, also known as UNS S21800 and 0Cr17Ni9Mn8Si4N, is an austenitic stainless steel with an excellent combination of corrosion resistance and mechanical properties. It is designed to resist both general and localized forms of corrosion and resist heat up to 1830°F (1000°C). It is a highly useful material and is used in applications ranging from chemical reactors, to salt storage tanks and more.
The material has a high tensile and yield strength, in addition to having good corrosion resistance and high resistance to oxidation. It is also highly resistant to sulfide stress cracking, which is important in applications such as petrochemical and marine. It is also designed to be stress-corrosion resistant, which means it can withstand corrosion in areas of high stress.
The alloy has good machinability, forming and welding properties. Nitronic 60 can be hot or cold formed to obtain the desired shape, and easily welded using conventional welding techniques. The material is resistant to stress corrosion cracking in water environments, and is often used in salt water applications.
In terms of physical properties, Nitronic 60 has a density of 0.293 lb/in3 (8443 kg/m3) and a melting range of 2550°F (1399°C) to 2650°F (1456°C). It has an ultimate tensile strength of 125 ksi (858 MPa), a yield strength of 115 ksi (793 MPa), and an ultimate impact strength of 32.0 ft-lbf (44J). It also has an elongation of 12%, a Brinell hardness of 290, and a Rockwell Hardness of 35.
