Sheet XH78T - EI435
chromium-nickel sheet XH78T of heat-resistant steel is designed for long-term work at t ° to 1100 ° C. His great qualities are retained after many years of operation in the most demanding conditions. Specific gravity 8.38 g / cm³. It is resistant to corrosion, plastic, even technologically very cold, easily welded. It has a high heat resistance and creep resistance. Its elongation at break = 25%. Tensile strength of 830 MPa, a modulus of elasticity of the 1st kind 2.19 MPa; thermal expansion coefficient of 12.2 [1 / deg]; The heat capacity of ~ 14.6 W / (m · deg).

Expensive elements such as chromium, nickel, titanium in sheet composition increases its cost. However, the high strength and durability XH78T alloy, recyclable — are paying off handsomely this high price. The disadvantages include sheet embrittlement in sour environments.
The chemical composition (GOST 5632 — 72)
Heat resistance, high resistance to creep and fracture in extreme temperatures make it possible to use a sheet, working under pressure at t ° 1000 ° C, in jet engines, internal combustion engine combustion chambers. XH78T sheet is used for the manufacture of conductivity of steam and paronagrevatelnyh pipes, various systems of ultra-high pressure, steam and gas turbines which can withstand very high temperatures and pressures. This list is used in engineering, construction, nuclear and oil industries. Heat resistance and high resistivity allow its use in electrical engineering. It extends the scope of the sheet and that it is perfectly welded. Robust, reliable and durable, meeting the highest requirements, it has proved to be the best side in the modern workplace.
