Hello,
SS316 is not magnetic having some Nickel in it (opposite case for 400 Series of SS where ther's 0% Nickel)
Could you advise what kind of welding rodes/fill material you used?

Normally, if you used a fit SS fill material , no reason to have such a magnetic property. If so, the only one resaon, could be the duplication of Nickel in the weldments because of used of pre-heat which is not required.

Hi Experts,

We have an issue where the Customer is going around on the a stainless steel (S316L) using a potable to check on the materials and welds

 

He has checked on some areas near the weldment where there is a force of attachment and the magnet is still sticking to the area

The magnet drops off when the magnet is moving away from the weldment

 

I request for a technical understanding to clarify with the customer

 

Appreciate your kind assistance  

 

Thank you

Best Regards
