НП1А-ID round, wire, tube, sheet, strip
relevance
Material marked НП1А-ID refers to the class of high-purity Nickel alloys. Such materials, thanks to the Nickel-based, has high corrosion resistance in environment of concentrated acids and alkalis, aggressive industrial environments and high electrical resistance. Most often, the equipment material of this type is used by the chemical industry. The manufacture and transportation of corrosive chemical substances such as caustic soda, liquid chlorine, mineral fertilizers can not do without such a robust and reliable raw materials.
