Composition and properties
Steel AISI 441 (1.4509) is a heat-resistant steel with increased corrosion resistance, including high temperature. This is ensured by the presence of chemical elements which provide double the stabilization of the structure of the material. Produced by North American standard ASTM, AISI 441 (1.4509) includes the following alloying elements:
|Percentage composition||Not more than 0.03||Not more than 1.0||Not more than 1.0||0,1…0,6||0,3…1,0||17,5 18,5…|
As an inevitable impurity metals, the composition of this grade of steel also includes sulfur (the amount does not exceed 0,015%), and phosphorus (0.04%).
The European equivalent of this steel is a steel grade X2CrTiNb18 produced s according to norms UNS 43940. The composition of the steel is almost identical question. In Russia and in the CIS analog steel AISI 441 (1.4509) no.
A characteristic feature of this material is a very high corrosion resistance against high-temperature, chemically aggressive substances gaseous or liquid. The above description remains fully raised to 9000 C temperatures and pressures on the surface of parts made from this steel. High surface hardness of the steel was due to the large amount of nitrides, which obrazujas in the process of smelting, to further effectively communicate with chrome. Steel is also characterized by an enhanced ability to weldability, which facilitates the fabrication of her composite structures.
Wire and the circle of this steel are easily handled with pressure and cutting. Punching is possible in a cold state, but with considerable degrees of deformation of steel required to pre-annealing (the temperature of the aging heat treatment furnaces — 700…7500 C, followed by cooling at calm air). The machining of the material to perform better with high speed steel tools.
Wire, steel, AISI 441 (1.4509) the well is subjected to drawing through a carbide skid road, after which possible automated landing on multiple machines. The intensity of strain hardening is low, and corresponds to the analogous process for conventional low-carbon steels.
Wire and bars of steel grade AISI 441 (1.4509) is used when the responsible production volume of machine parts operating under conditions of pitting corrosion: the pistons and the pumps and compressor units, units for pumping chemically aggressive environments, and in the other nodes, which operate at elevated pressures and temperatures. The durability of parts do not affect the value of the PH of the external working environment, the temperature of the heating surface (within specified values), and friction conditions. This is due to the high resistance existing in the surface layers of carbides and nitrides of chromium, stabilized by niobium and titanium.
To by wire and round stainless steel ferritic AISI 441 (1.4509) vendor price the company offers Electrocentury-steel. When this is fully provided with the desired range of diameters, type of the ordered assortment. Each batch is provided with a quality certificate from the manufacturer of the steel.
