Rod made of 32NKD alloy
Characteristics of the alloy
Precision alloy of 32NKD grade with an average index of linear expansion thermal coefficient is intended to be jointed with glass С 72−4, mica, or ceramics. This is alloy with an average index of a linear expansion thermal coefficient (6,0−9,0)·10-6 deg-1 at a temperature range from -70 up to + 470 °C. Such a grade of alloy as 32NKD is not allowed to use from 01.01.1991 in modernizing appliances or equipment that is again manufactured. Melting point of alloy is 1450 °C.
Precision alloy is a metallic alloy, which possesses unique physical and mechanical characteristics (magnetic, elastic, heating, electrical etc.). Precision alloy has a rank of properties that characterize an accuracy of chemical composition, carefulness of manufacture and processing, an absence of various residual elements. Usually, an actual category contains highly-doped alloys. Precision alloys are manufactured on a basis of iron, nickel, copper, niobium, cobalt. This group is used in precision machine tool building, innovative technologies, laser technology, for manufacturing accurate electronic devices, household units, metrological and measuring gauges.
Welding:

Description |
| 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 |
