WitrynaFor industrial applications involving only pure nitric acid, the stainless steels generally possess sufficient corrosion resistance. The chromium-bearing nickel alloys are only required if other chemicals, notably the halides and/or halogen acids, are present, or if the equipment has multiple uses involving different chemicals. WitrynaStainless steel is the most durable of metals. Its mechanical properties enable its structures to remain extremely resistant to rust. Nevertheless, corrosion can’t be precluded. But there are ways to mninimize the risk of corrosion. Stainless steel’s fine layer of chromium oxide has natural techniques to self-repair when breached or broken. mega leather shop
