Precision alloy 32NK-VI with specified temperature coefficient of linear expansion is used for connection with the glass and for parts with polished surface. Temperature coefficient of linear expansion ТКРх106 in the temperature range -60+20°C +20 to +100°C is not more than 1.5 [1/°C]. This alloy demonstrates a rare physical characteristics: magnetic, elastic, thermal, electrical. Belongs to the category of high-alloyed alloys. Its high quality due to the precision of the chemical. composition, thoroughness manufacturing and processing, absence of impurities. Precision alloy based on iron, Nickel, copper, niobium, cobalt, are used in precision machine tools, innovative technology and laser technology for manufacturing precision electronic devices, home appliances, calibration and instrumentation. Alloy 32NK-VI is relevant for parts with polished surface and for airtight connection with the glass.

Welding:

weldability limited

— welding is possible in the process of heating up to temp. 100−120? C and further thermal treatment

konovalivka

in order to obtain quality welded joints, it is necessary to perform additional operations: during welding heating up to temp. 200−300°C, heat treatment (annealing) after welding.

Welded without any restrictions

— welding is carried out without further heat treatment and pre-heating.
