Sachiya Steel International is One Of The Leading Manufacturer And Exporter Of High Quality Super Duplex S32750 Tubes, which is highly resistant to carbide – related inter – granular corrosion. Due to the ferritic portion of the duplex structure of Super Duplex S32750 Seamless Tubes it is very resistant to stress corrosion cracking in warm chloride containing environments. The high – temperature strength of Super Duplex S32760 Welded Tubes is basically the same as SS 430 in the range of 950 Degree C – 1150 Degree C. Super Duplex S32750 EFW Tubes should be noted that the strength increases abruptly below 900 Degree C.

However, because descaling is somewhat difficult for Super Duplex S32760 ERW Tubes in comparison with SS 304, alkali immersion before acid pickling, and if possible, shot blasting are extremely effective. Solution annealing in Super Duplex S32750 Round Tubes should be done after hot working, where a mixture of nitric acid and fluoric acid is used in pickling.
Regarding cold workability in Super Duplex S32760 Square Tubes, care is required as proof stress is high and elongation is low in comparison with Grade 304. The high chromium and molybdenum content of Super Duplex S32750 Rectangular Tubes make it extremely resistant to uniform corrosion by organic acids like formic and acetic acid. Super Duplex S32760 Electropolish Tubes also provides excellent resistance to inorganic acids, especially those containing chlorides.
