ASTM A790 UNS S31803 Duplex stainless steel seamless tubes whose microstructure consists of a mixture of austenitic and ferritic phases. Meanwhile, stainless steel alloy grades such as UNS S31803 have proven particularly useful in applications susceptible to stress-related corrosion cracking. SCC or stress-related corrosion cracking in piping can have a detrimental effect not only on plant workers, but also on the business itself.
