ХН70ВМТЮ - ЭИ617 sheet, circle, wire

ХН70ВМТЮ - ЭИ617 sheet, circle, wire

Are you interested in a sheet, a circle, wire from alloy ХН70ВМТЮ from the supplier — the company АвекГлоб? Here you will find the necessary information on this topic

Company Avecglobal sells at affordable prices from the manufacturer sheet, circle and wire made of corrosion-resistant, heat-resistant alloy grade HN70VMTU. The supplier ensures guaranteed delivery of products to any address specified by the consumer.

Composition and application

Chromium-nickel alloy of the brand KhN70VMTU (also called EI 617), additionally doped with molybdenum, tungsten, titanium and aluminum, is included in the group of alloys with special heat resistance characteristics. Intensive formation of scale on the surface of products that are made from this alloy begins only at ambient temperatures exceeding 800… 950 0 С. At the same time, due to the increased (against the usual) content of refractory molybdenum and tungsten, a sufficiently high mechanical strength is also preserved in conditions of long-term operation. Therefore, the working parts of turbines and gas turbine engines (blades, fasteners, various guiding elements) are made from alloy ХН70ВМТЮ.

The chemical composition of the alloy, which meets the technical requirements of GOST 5632−72, is given in the table (numerical data — in percent, nickel — the rest):

Fe C Si Mn S P Cr Ce Mo W Ti Al B
Not more than 5 Not more than 0.12 Not more than 0.7 Not more than 0.5 Not more than 0.02 Not more than 0.05 13… 16 Not more than 0.02 2… 4 5… 7 1.8… 2.3 1.7… 2.3 Not more than 0.02

To buy at different prices from the manufacturer a different range of rolled products — sheet, wire or a circle — which is made of a high-temperature nickel alloy based on the brand KhN70VMTU (EI 617), offers the company AVEKglob. The supplier guarantees timely delivery of products to any point set by the customer.
