UNS S31603

HuaNickel PRODEC 316/UNS S31603 is an improved version of the standard HuaNickel UNS S31603 for improved machinability and superior uniformity. PRODEC’s consistency and optimal machinability allow machining at higher speeds and feeds to produce high-quality parts at the lowest total cost. For automatic screw machines that require extensive processing, extensive processing should be considered.
