Hi all.
I am a hobby sculpture maker. I have recently made an item from stainless steel cutlery, 18/10 and 18/0 grade as stated on the packaging. Mig welded with stainless wire with argon/co2 mix. The test item has been grit blasted to remove the polished surface and give a texture. As the item has been exposed to the weather it has developed a rust finish, as in what seems microscopic rust dots , as in the pits made by the gritblast finish , just covered with thousands of rust dots, just pinpoint size, even the weld material is affected.
Question, could the blast media, possibly having been used on carbon type steel previously, caused this by contaminating the surface. The company that carried out the grit blasting was aware that the item was stainless steel, or is this type of stainless (?) possible to rust in a fashion.
The 18/10 items ( well known kitchen brand) are less affected than the budget items (18/0).
Hope some one can advise.
