Does Stainless Steel tarnish?
Everyone loves wearing jewelry, especially when it’s made out of stainless steel. That isn’t a surprise because stainless steel is cheaper, but it’s durable and can undergo some wear and tear. However, even though it’s durable, people are still asking questions such as whether jewelry made of stainless steel tarnish or is stainless steel waterproof? Those are some great questions and people should know whether their jewelry will last for a long time and how to take care of it. So, let’s see how durable this metal is.
Does Stainless Steel rust?
Generally, jewelry made out of this metal does not tarnish. However, it’s not indestructible. Yes, you can wear your stainless steel jewelry all the time and every day, but it’s eventually going to get some scratches and stains because of the constant wear and tear. Also, just like anything else, stainless steel can rust, but it depends on the environment. But, stainless steel jewelry will take much longer to rust than any other jewelry, but it can also depend on a lot of things.
Stainless steel which is used in the production of jewelry is an alloy of nickel, carbon, chromium, manganese, and iron. And even though most of these metals do rust, stainless steel is more resistant due to chromium, which protects it. Chromium works by protecting the metal from oxidation, so, it’s less likely to rust or tarnish, and this is why most jewelry made out of stainless steel has at least 10% of it.
