S32205 / S31803 Big Size Duplex Steel Pipe With Annealed &
Pickled Surface For Chemical Industry
Duplex stainless steel that was developed to combat common
corrosion problems encountered with the 300 series stainless steels
. “ Duplex ” describes a family of stainless steels that are
neither fully austenitic , like 304 stainless , nor purely ferritic
, like 430 stainless . The advantage of a duplex structure is
that it combines the favorable qualities of a ferritic alloy (
stress corrosion cracking resistance and high strength ) with those
of an austenitic alloy ( ease of fabrication and corrosion
resistance ) .
Use UNS32750 super duplex stainless steel pipes can
improve corrosion resistance compared to other materials . And
super duplex steel pipes have greater tensile and yield strength ,
good ductility and yield strength , good stress corrosion cracking
resistance . Also can help clients reduce their purchase costs ,
but can gurantee the quality etc .
