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 .

A: We do sell tubing on an individual basis however there is a $50 "broken box" fee applied to any order less than an entire case.Since we don't offer a way to order individual tube pieces online please call us to place an order over the phone.
A: Yes, our tubing comes in standard 20 foot lengths and will need to ship via freight. I'd also like to mention that there is a broken box charge meaning that if you do not order an entire box of tubing you will be charge additional fees as such. For more information please contact us. Thanks.
