Duplex alloy EN 1.4410 / 03X24H6AM3

Steel 1.4410 / 03Х24Н6АМ3

Super duplex steel 1.4410 is a quality raw materials with the highest mechanical strength and resistance to corrosion. The products of these alloys are characterized by high resistance to wear and almost are not amenable to General, crevice or pitting corrosion. For this reason, from raw material produced the most in demand for industry product: seamless steel pipe used in the oil industry and gas transportation system. In addition, steel produced steel flanges, durability which is almost twice higher than that of peers. Features Stainless steel grade 1.4410 is a ferritic-austenitic alloy consisting of iron, magnesium, phosphorus, manganese, silicon, molybdenum, copper. Alloy perfectly processed and easy to weld. The increased strength allowed the use of steel in structures where it is necessary to minimize the total weight of the structure. Pipe seamless alloy of this type is in itself, when used in acidic and corrosive environments, which allows the use of these products for transportation of highly aggressive fluids. Purpose and scope Steel of this type is used for the production of tanks and pipelines high pressure pipelines, storage tanks of chemical wastes, heat exchangers. In addition, steel demand in the food industry and in medicine.
