RE: [MW:17400] Austinitic Stainless steel piping, corrosion environnement

Dear sir u mean pickling/passi for all weld joints?

No problem to use the austenitic SS mentioned for the said environment.  As long as a) the complete SS fabrication has been properly 'pickle and passivated' strictly in accordance with manufacturers product data sheets and b) there is no contact between other materials (i.e. dissimilar materials) after final installation where galvanic corrosion could generate , i.e. design should allow for proper insulation between dissimilar materials.

Dear experts,

  Need your help.

Need to confirm if we can use austinitic stainless steel piping (A312 304L & 316L grades)  for maritime environnent and any risk of corrosion.
