Material with the marking of HN63MB or as it is sometimes called in older sources, EP758U belongs to the group of nickel raw materials with high anticorrosive properties and considerable resistance to high-temperature operating modes. Heat resistance and other individual qualities of such raw materials are due to its perfectly balanced chemical composition containing a whole complex of various substances. Due to such characteristics, the material of this brand is usually used in the manufacture of high-strength and reliable chemical equipment capable of operating under rather difficult production conditions. Also, such raw materials are used in the oil refining industry, in the pulp and paper industry and in the manufacture of systems controlling atmospheric pollution.
