KHN28VMAB - эп126 sheet, round, wire

KHN28VMAB - эп126 sheet, round, wire


Alloy ХН28ВМАБ ЭП126 — heat-resistant high-alloyed chromium-nickel steel, which contains nickel 25−30% and chromium up to 22%. As additives to the charge add silicon — not more than 0.6%, phosphorus — up to 0.02%, manganese — 1.5%, tungsten — 6.5 — 7.5%, molybdenum — about 2.8 — 3, 5% and sulfur — 0.02%.

The temperature of the semi-finished products is 1170 ° C at the beginning, and about 850 ° C at the end. Finished products with a cross section up to 350 mm are cooled in air. Steel pipes of the brand KhN28VMAB mainly produce a round section, and under the order — with oval, rectangular and square. Pipes ХН28ВМАБ are classified by diameter and thickness of the wall. With a diameter of 5−250 mm and a wall thickness of 0.3−6 mm, the pipes are called special. Thin-walled have a diameter of 5−250 mm and a wall thickness of 0.6−20 mm. Thick-walled pipes have Ø from 6 to 250 mm, wall thicknesses of 1.6 to 24 mm. Very thick-walled pipes are made Ø from 6 to 70 mm, wall thickness from 2 to 12 mm.


Rolling, having a diameter of less than 9 mm, is realized in coils, and above 9 mm it is delivered by straight segments, which after dividing into non-dimensional, dimensional, and also multiple dimensional segments. High-alloy high-quality steel ХН28ВМАБ allows to produce products of any dimension


Pipes brand KhN28VMAB used in high-pressure systems. Such pipes are often used in the nuclear and chemical industries, in various furnaces and boilers, in furnace conveyor production at temperatures of about 750 — 850 ° C, in the manufacture of boxes for carburizing. The class of pipes allows them to be used in machine building, the production of bearings, separators and other rolling elements.
