Technical characteristics

Steel of grade HN78T is intended for manufacturing details that are exploited at a high temperature (1000−1100ºС) in aggressive chemical environment. Due to a high content of nickel and chrome, details that are made of this alloy have a high corrosive resistance. The main demerit is a non-resistance in sulfide environment. Due to a high content of nickel, chrome, titanium, it has a high cost. However, its high cost is offset by reliability, long operational life and strength of a material.

Percentage composition complies with GOST 5632−72. Steel is smelted in open electrical furnaces that give a minimal quantity of residual elements.

Percentage composition of alloy

Ni Fe Cr Ti Mn Si P C S
70.003−80.85 ≤6 19−22 0.15−0.35 ≤0,7 ≤0,8 ≤0.015 ≤0,12 ≤0,012

Physical characteristics at a temperature of 100 °C

— thermal-expansion coefficient is 12,2 [1/deg];

— module of elasticity is 2,19 MPa;

— heat conduction coefficient or heating capacity of alloy is not more than 14,6 V/(m*deg);

— alloy density is 8, 38 g/cm³. It can insignificantly change at a temperature rising;

— electrical resistivity- 1,1 Ohm-mm2/m;

Wire surface does not oxidize at durable exploitation or at a high temperature in oxidizing atmosphere. Such a wire is malleable. This makes it popular in a manufacture of electrical and industrial appliances.

Application

Mill-products of this grade find a wide application in process heaters of electrical furnaces. F. e. it is used in kilns, in electrical furnaces, in tools of thermal effect, in household appliances. Wire of this grade is much-needed in rheostats and resistor elements; in manufacture of vacuum device elements, coppers, plates of increased reliability. It is also can be used in a function of cutting or heating element in packing thermal knives; in industrial and household air-heating and water-heating systems. Wire length determines on the basis of objective power in manufacture of springs. Its increased plasticity allows performing a rolling at low temperatures, thereby reducing energy demands. Due to a heat resistance of wire HN78T, it is widely used in aggressive environment in the capacity of chemically resistant alloy. Nowadays, the widest application of such wire is found in petrochemical mechanical engineering.
