Composition and properties
Resistant to external manifestations of corrosion steel grade 1.4104 low carbon content, and the presence in its composition of molybdenum and chromium, which is confirmed by the following table:
|Availability in steel, %||0,10 0,17…||Not more than 1||Not more than 1.5||15,5 17,5…||0,30…0,60||The rest|
As inevitable smelting impurities in the smelting in the composition of the considered steel there are also chemical elements such as phosphorus (0.04%) and sulfur (in the range 0,15…0,30%).
Rolled sheet produced in accordance with the standards of AISI (USA), and according to the European standard EN 10088−3. Similar to the steel composition has, in particular, steel Х14СгМоЅ17 produced the European iron and steel companies. In Russia and the CIS grade of steel 1.4104 do not exist.
Sheet and strip from the stainless steel characterized by the following physico-mechanical characteristics:
- Density, g/cm3 to 7.7;
- Tensile strength tensile, MPa — 750…800;
- Brinell hardness number, HB — 120…130;
- Elongation of the cross section % — 20…24.
Flat rolled steel this steel is produced in hot and cold phases. Hot-rolled sheets have a thickness over 20 mm, and the tape is produced only by the technology of cold rolling.
The presence of sulfur steel 1.4104 provides reduced voltage to the slicer. As a result, the metal lends itself well to the separation operations of the sheet metal forming — cutting and punching, including in automatic mode. When applying the appropriate lubrication may also perform a flexible and shallow hood (for the more serious of the deformation necessary to provide interoperable ezuprechnaya treatment — annealing at 180…2000 C With subsequent air cooling).
Steel 1.4104 is characterized by a favorable combination of the main alloying elements. In particular, the molybdenum contributes to the improvement of the deformability of the sheet and strip and chrome gives the finished product desired resistance against high-temperature corrosion-mechanical wear. Application
Hot rolled plates of this steel has been widely used in the production of flat and spatial parts of machines, the functioning of which occurs in corrosive environments, liquid and gaseous. Low corrosiveness of the surface layers is fully maintained up to temperatures of 350…4000 C. Typical parts made of steel 1.4104 corps of headers and responsible ventilating equipment, parts control and measuring equipment, etc.
To buy rolled metal tape or sheet of resistant against corrosion of steel 1.4104, on the proposal of the company Electrocentury-steel — advantageous and convenient. Provider fully provided the required range of thicknesses, widths and lengths of metal, and each party is accompanied by a certificate of quality.
