36KNM ribbon, round, wire
Grade 36KNM relates to magnetically soft steels which have high corrosion resistance, high induction in medium and weak fields and low coercive force. A distinctive feature of the brand 36KNM alloy is highly resistant to corrosion and sufficiently high value of magnetic induction in weak fields. Basically, the alloy used in the manufacture of magnetic wires, which are operated in aggressive environments (sea water, etc.).
In its composition the alloy 36KNM, in addition to iron (base), includes cobalt (36%), Nickel (22%), molybdenum (2.9−3.3%). As alloying additives used alloy silicon manganese.
| 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. |
