Composition and application
The high-temperature alloy of the brand Kh27Yu5T (EI 626) is a four-component alloy with iron, chromium, aluminum and titanium, which is intended for use as heating element elements with a heating temperature of not more than 1400 0 C. The permissible temperature is determined by the wire diameter — for example, diameter up to 1 mm, it is 1200 0 C, up to 3 mm — 1350 0 C.
The alloy is used for the production of heating elements for laboratory heating plants, metallurgical furnaces, reactors in the chemical industry, heat resistors. The addition of titanium increases the heat resistance of the alloy, and the presence of chromium gives the material the necessary resistance against high-temperature corrosion, including in chemically aggressive media containing carbon, hydrogen and sulphides.
The alloy X27Y5T (EI 626) is sensitive to dynamic loads, and at critical temperatures it is prone to sagging.
The chemical composition of the alloy, which meets the technical requirements of GOST 10994−74:
Iron,% — 65… 68;
Chromium,% — 26… 28;
Nickel,% — up to 0,6;
Titanium,% — up to 1.0;
Manganese and silicon,% — up to 0,60;
Company Avecglob proposes to purchase at economically advantageous prices fecral wire from alloy grade Kh27Yu5T (EI 626). The supplier ensures guaranteed delivery of products to any point. installed by the client.

The coefficient of linear expansion in the temperature range 20… 1000 0 С, μm / deg — 15;
Specific heat capacity, kJ / kggrad — 0.48;
Specific electrical resistance, Ohmm 2 / m — 1,3.
Basic mechanical characteristics of the alloy:
The limit of time resistance. MPa — 760… 780;
Yield strength, MPa — 450… 550;
Relative elongation,% — 10;
Hardness according to Brinell, HB, no more than 250.
Technological features of the alloy — machinability by plastic deformation — poor, weldability — satisfactory (preheating of the joined parts up to 250… 300 0 С is required). The alloy has a ferrite structure. Ferromagnetic, at elevated temperatures prone to oxidation. The range of produced wire is from 0.1 to 10 mm.
