The composition of the heat-resistant steel tape HN77TYUR brand (formerly known as EI437), regulated by GOST 5632- - — — 72. Foreign counterparts of this alloy are steel Inconel, Incoloy, Hastalloy. This tape has high quality. Part of the titanium alloy strengthens HN77TYUR, optimizes technical characteristics, giving the tape a uniform solid structure. Nickel forms a surface oxide film that protects the tape against corrosion and is easily restored with little damage.

Tempering is carried out at 1090−1120 ° C, cooled in air or water. Aging takes place at t ° 700−750 ° C from 12 to 16 hours. Weldability limited. For lasting weld required preheating up to 200 — 300 ° C with a final annealing after the welding.
The tape is resistant to soil and atmospheric corrosion, has a minimal tendency to brittle fracture at low temperatures. Designed for continuous operation at t ° up to 750 ° C, characterized by high resistance to nitric acid, sulfuric acid, corrosive environments of industrial gases. Resistant to hot condensate, to meet the stringent sanitary requirements.

Such expensive metals such as chromium, nickel, molybdenum, titanium in the steel HN75MBTYU, affect its cost. However, high strength, reliability and durability of the belt, the possibility of recycling material — reduces the high cost of practically in long-term investments.
Such a heat-resistant nickel tape tech and resistant to corrosion (seawater, hot condensate vapor) in conditions of extreme heat demand is very widely. It — mechanical engineering, energy, gas production, chemical and oil industry, «defense industry». From produce tapes details combustion turbines and internal combustion chambers — like moving (rotating), and fixed (static). Compliance with the requirements of SNIP doing this tape in demand in medicine and food industry.
