Stainless steel(rusty)

[Barry Wolk]

We have a stainless steel outdoor sculpture that rusted. The artist came out and wire brushed the rust off and it came right back. Wire brushed it again and it came back. He was totally confused as he knew the stainless shouldn't rust.

I figured out that he was using iron wire wheel brushes and bits of iron were being imbedded in the stainless and that's what was rusting.

I think your on to a theory I would agree with. I weld a lot of stainless and have shown a few how to do sanitary welds in plumbing and occasionally I will see a welded section that will turn rusty if left outside in the weather & it is not polished correctly, the use of a (clean) Stainless brush is crucial in Stainless and Aluminum welding.

304 and 308 is what they use in commercial kitchens. it will get rust stains on it but will wipe off. i live 4 miles from the atlantic ocean and everything rusts here. 316 is marine grade stainless and seems to last forever around here.
