Composition and properties
Heat-resistant stainless steel AISI 441 (1.4509) is a ferritic steel with dual stabilization properties, and enhanced ability to weldability. Pipe rolling, this steel is produced with the following components of its chemical composition:
|Content,%||0.03||To 1.0||To 1.0||0,1…0,6||0,3…1,0||17,5 18,5…|
As inevitable smelting impurities in the smelting stage, the initial billet to the steel composition also includes sulfur (up to 0,015%) and phosphorus (0.04%).
The European analogue of the considered steel — steel X2CrTiNb18, which is manufactured according to the Euronorm UNS 43940. From this steel it differs somewhat lower percentage of chromium (16 to 18%). Domestic standards such grade of steel do not provide.
Specific properties of steel AISI 441 (1.4509) is the increased corrosion resistance that most actively manifested in significant mechanical loads on the inner surface of the pipe. The number of carbides in the resulting macrostructure is very small, and effectively communicates with chrome, which increases the strength properties of the material.
The effect of alloying elements on the properties of tubular steel, this steel is shown in the following. Chromium provides the resistance of the steel from pitting corrosion, which is particularly aktiviziruyutsya at elevated temperatures. Titanium and niobium reduces the activity of the steel to intergranular corrosion. Improved oxidation resistance is retained at temperatures up to 900…9500 C. the Steel is characterized by high resistance to aggressive chemical environments, in particular, Halogens alkali metals.
Steel AISI 441 (1.4509) has good ductility, which allows for the spatial bending of pipes without heating, regardless of the complexity of deformation. Due to good weldability of piping made from this steel can be connected one-way, and by means of flange connections.
Pipe in stainless steel AISI 441 (1.4509) can effectively be used in the repair, construction and maintenance of pipelines, where is the pumping chemically aggressive liquid and gaseous environments at elevated temperatures. It does not matter acidic PH, as the inner surface of the pipe, as well as a preview of their thermal treatment.
Due to the stabilization of the structure and properties of steel on its surface layers are formed resistant to temperature carbides and nitrides of chromium. As a result, the strength of the surface layers increases, and the steel can activity to counteract the processes of corrosion-mechanical wear. This allows you to install pipes of this steel into a powerful blower units, the scrubbers and the purifiers metallurgical devices.
Buy a tube of corrosion resistant steel AISI 441 (1.4509), signed a contract for the supply of tubular steel products with Electrocentury-steel. The vendor guarantees the price from the manufacturer, with any range of internal diameters and thicknesses, and ensures each batch of product quality certificate.
