Grade analogue W. Nr. Aisi Uns En Order
32NK EP475 Buy from stock, view availability


Precision grade 32NK with a defined linear expansion thermal coefficient is used at pressure-tight joint with glass and for details with a polished surface. Linear expansion thermal coefficient CTP x106 is not more than 1,5 [1/°C] at a temperature range -60°+20°C and +20 +100°C. This alloy demonstrates rare physical characteristics: magnetic, elastic, thermal, electrical. It relates to a category of high alloys. Its high properties are caused by an accuracy of chemical composition, carefulness of manufacture and processing, absence of residual elements. Precision alloys with a defined TCLE on a basis of iron, nickel, copper, niobium, cobalt are used in precision machine tool building, innovative technologies, laser technology, for manufacturing accurate electronic devices, household units, metrological, measuring gauges.

limitedly weldable

— welding is possible at heating to 100−120°С and last heat treating

hardly weldable

— in order to obtain a qualitative welded joints, it is necessary to perform the following operations: while welding to heat it up to 200−300°C, heat treating (annealing) after welding.

weldable without stint

— welding is done without further heat treating or previous heating.
