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.

Welded pipes is carried out on sophisticated tube mills where the cold roll stainless steel strips are welded into tubes in a fully automatic process.

Tubing surfaces are available bright annealed or mechanically polished ID to 20 μ-in Ra(0.5 μm)maximum and/or OD polished to 30μ-in Ra(0.8 μm)

All technical data of each inquiry must be evaluated by company professional expert and get confirmation by our cooperation mill.

From advanced manufacturing processes, including special cold drawing, not just precision for sizes, but also enhance material substrutes density
