Strip made of 40KHNM alloy
Characteristics of alloy
Precision alloy 40KHNM relates to high alloys with unique physical and mechanical characteristics: magnetic, elastic, thermal, electrical etc. It differs with an accuracy of chemical composition, a preciseness of manufacture, processabilty, and absence of residual elements. Precision alloys are manufactured on a basis of iron, nickel, copper, niobium and cobalt. This group is used in precision machine tool building, innovative technologies, laser technology, for manufacturing accurate electronic devices, household units, metrological-measuring gauges.

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 |
Mechanical lasting-quality of mill products at a temperature 20 °C.
