The most common causes of rust in stainless steel tanks are the welds holding everything together. The best way to avoid it is to use TIG Welding. Here at Letina we go a step further, brushing and polishing the welds to make sure our stainless steel tanks have no weak spots.
Another common cause is stainless steel tanks getting contaminated by normal, non-stainless metals. Rust can spread by contact, which is why manufacturers mustn’t cut costs and use inferior parts on their tanks. Letina tanks use stainless steel components exclusively.
If you’re working in a corrosive environment, such as near salt-water or using corrosive chemicals, stainless steel can begin to rust. That is why in such environments AISI 316L stainless steel with superior corrosion resistance is used.
