Tape HN77TYUR - EI437BU
The composition of the strip of heat-resistant steel brand HN77TYUR (formerly known as ЭИ437), regulated GOST 5632 — — — — 72. Foreign counterparts of this alloy are steel Inconel, Incoloy, Hastalloy. This tape has a high quality. Part of the Titan hardens the alloy HN77TYUR, optimize specifications, giving the ribbon a uniform solid structure. Nickel forms a surface oxide film which protects the tape against corrosion and is easily restored with minor damage.

Hardening is carried out at 1090−1120°C, cooled in air or in water. Aging takes place at a temperature of 700−750°C of 12 to 16 hours. Weldability is limited. To obtain a strong weld is required pre-heat to 200 — 300 °C final annealing after welding.
Tape is resistant to soil and atmospheric corrosion has a minimal tendency to brittle fracture at low temperatures. Designed for continuous operation at t° to 750 °C, has high resistance to nitric, sulfuric acid, corrosive environments and industrial gases. Resistant to hot condensate to meet the most stringent sanitary requirements.

Such expensive metals as chromium, Nickel, molybdenum, titanium in the steel composition KHN75MBTJU affect its cost. But high strength, reliability and durability of the tape, the possibility of recycling of material reduces the cost of virtually long-term investment.
Such Nickel-ribbon technology and corrosion resistant (sea water, hot vapor condensate) in extreme temperatures demand very widely. This — the engineering, energy, gas, chemical and petrochemical industry, the defense industry. Ribbon manufacture components of the combustion chambers of internal combustion engines and turbines as the moving (rotating) and fixed (static). Compliance with the requirements of SNIP make such a tape used in the medicine and food industries.
