Duplex alloy EN 1.4418 / 08X17H5MZ

Steel EN 1.4418 / 08H17N5MZ

Stainless steel grade 4418 is characterized by the highest mechanical strength and corrosion resistance. This alloy finds wide application in industry and manufacturing, while maintaining its operating characteristics in a wide temperature range. Features High corrosion resistance of surface, plane and point types this alloy could be used in shipbuilding, due to the presence of molybdenum additives. The alloy shows their best side in a hydrochloric atmosphere, the interaction with hydrochloric and sulfuric acid. Steel 1.4418 is inexpensive compared to stainless steel counterparts, the price of which in our company is one of the most affordable on the market. When welding and forging, and further processing must comply with the technical conditions specified in the documentation for alloy. Use Buy stainless steel of this type is necessary for the needs of ferrous metallurgy (production of metal sheets, wire and so on), and use: • shipbuilding; • in the oil and gas industry; • in the mining industry; • in the chemical industry; • in medicine. The alloy is characterized by a high degree of corrosion resistance at the molecular level and can withstand critical high pressure. Chemical composition of steel 1.4418
