Is it Industry Standard to passivate 316L Stainless Steel after welding? [Washington] 

October 24, 2009

Working on a project using 316L steel metal, advised fabricator that passivation of the welds should be done. For whatever reason they were not done in the shop and now the question arises "you never provided written direction to passivate" ?

John,

Your fabricator is right,if you did not ad it to the written specs, he does not have to passivate.
It is not industrial standard to passivate SS. Following the written specs is industrial standard.
But he will certainly do it if you order it and accept the additional cost.

Kind regards,

Marc.
