Нержавеющая сталь 1.4505 / AISI 441

Stainless steel 1.4505 / AISI 441

Steel brand 1.4505 / AISI 441 belongs to the group of ferritic stainless steels stabilized by niobium and titanium. Significant content in the chromium provides resistance to crevice corrosion and allows this stainless steel buy as a counterpart to the standard austenitic grades. Special features The main properties of steel include: - resistance to intergranular and crevice corrosion; - resistance to oxidation at temperatures up to 950 degrees; - low coefficient of thermal expansion; - high thermal conductivity. Stainless steel sheet, the brand 1.4505 / AISI 441, may be subjected to cold working, including bending, deep drawing and so on. The steel has a high rate of temporary resistance, which, given the low rate of work hardening, makes it very suitable for deep drawing. Possible to weld steel using conventional methods and filler materials. Applications Available in this stainless steel price, promotes its widest application. Brand 1.4505 / AISI 441 successfully used in the production of heat exchangers, various elements of the car, covering elevators, plumbing, washing machines, decorative elements decoration and so on.
