Technical characteristics

Modern metallurgic industry is engaged in manufacturing the following mill products from alloy Ni36:

hot-rolled plate;
hot-rolled rod;
cold-rolled strip;
seamless tubular;
beaten rod etc.

Ni36 Invar is a type of precision alloys. It has a defined LCTE and contains in its composition a basis of iron (63−64,5%) and nickel (35−37%). Alloy has a small linear coefficient of thermal expansion (- 1,5x10-6 1/°С temperature is -80 + 100°C). It defines its usage in manufacturing details of checking and measuring instruments. Such tools work at marginal climatic temperature gradients, keeping a fixed dimension of this temperature range. It is alloyed with silicon, cuprum, mangan, aluminium, molybdenum, vanadium. Ni36 is obtained by a method of vacuum induction melting. This steel is often used with an effective layer of other alloys (20NG, 75GND, 19NH, 24NH). As a result, there appear thermostatic bimetals of different grades.
