The term is a bit of a misnomer. There’s no one combination of iron and alloying elements that makes stainless steel what it is. Instead, stainless steel refers to the fact that products made from it do not rust.Alloys in stainless steels can include chromium, manganese, silicon, nickel and molybdenum. These alloys work together to interact with oxygen in water and air to quickly form a thin but strong film over the steel that prevents further corrosion.Naturally, stainless steel pipe is used in any industry where corrosion protection is necessary. While stainless steel pipe is essentially alloy pipe by another name, it is not well suited for extreme service unless it’s been appropriately heat treated to increase strength and impact resistance.Due to its aesthetic appeal, stainless steel is often chosen if pipe must be visible in public or professional settings.
