Heat-resistant steel of grade X15CrNiSi25−20 relates to high-alloyed alloys on iron basis. It is smelted in induction furnace. It consists of chrome — 24−27%, nickel -18−21%, molybdenum and copper — 0.3%, manganese — 1.5%, carbon, vanadium, tungsten, titanium — 0,2%, silicon — 2−3%, additives of sulfur and phosphorus — hundredths of percent.
Percentage composition according to GOST 5632−72. Iron is a basis.

Alloying increases workable properties of steel: heat resistance, capability to resist aggressive environments. Jumping up temperature of semi-fabricates constitutes 1170 °C at the beginning and 850 °C at the end. Termohardening is performed in air at a temperature of 1050−1150°C.
Heat-resistant pipe X15CrNiSi25−20, aisi 314 is resistant to corrosion in air and hot gas environments. Such a tube, alloyed with chrome, nickel, silicon, molybdenum, vanadium, tungsten, can withstand contact with aggressive environment for a long time because while heating alloying additives form protective oxide films that prevent corrosion. Heat-resistant steel X15CrNiSi25−20, aisi 314 is fairly malleable. This allows making the most complicated constructions out of it. This metal has an attractive appearance and does not require a painting.
It is used in a manufacture of travelling kiln grids, slot furnace rollers. They serve for fast firing of ceramic tiles, for flat household ceramics and other ceramic products. Heat-resistant X15CrNiSi25−20, aisi 314 pipe is utilized in parts of burner devices. It is also used in a manufacture of electric thermal transducer casings because it does not contaminate thermocouple electrodes and guarantees a reliable protection to thermocouple while working in conditions of aggressive environment. Such tube can withstand a temperature of 1000 °C under load for a long time. It also possesses high resistance to creep flow under load. It is used for furnaces of steam and gas turbines, jet engines, nuclear reactors, nuclear power units as a means of bearing material.
