UNS 32750 material is a super duplex stainless steel with 25% chromium, 4% molybdenum, and 7% nickel. The high molybdenum.

Micro structure Analysis
Grain size examination
Polishing Machine
Electro Etching Machine
Inverted Metallurgical Microscope

Benefits of UNS32750 Pipe:
Improved corrosion resistance in comparison to Duplex
Greater tensile and yield strength
Good ductility and toughness

Duplex 2205 is used in environments where resistance to general corrosion and chloride stress corrosion cracking is important.
