Description
Alloy 36N used: for the manufacture of parts of instruments, requiring constant size in the range of climatic temperatures; as the passive layer in the manufacture of thermostatic bimetallic, is used for making sensitive to the temperature change of the elements of control and measuring instruments and apparatus.
When using alloy grade 36N and the active layer of the alloy 75GND made thermobimetals brand ТБ200/113 (ТБ2013), which is used for the manufacture of heat-sensitive elements of the devices (thermal relay, fuse, thermometers and so on.).
When using alloy grade 36N and the active layer of the alloy 20NG made thermobimetals brand ТБ148/79 (ТБ1523), which is used for the manufacture of heat-sensitive elements of devices (compensators, relay protection, etc.).
When using alloy grade 36N and the active layer of the alloy 24NKH made thermobimetals brand ТБ138/80 (ТБ1423), which is used for the manufacture of heat-sensitive elements of devices (relays, regulators, pulse sensors, fuses, etc.).
When using alloy grade 36N and the active layer of the alloy 19NKH made thermobimetals brand ТБ129/79 (ТБ1323), which is used for the manufacture of heat-sensitive elements of devices (relays, regulators, pulse sensors, fuses, etc.).
