Magnetic temperature compensation soft magnetic alloy, within the ambient temperature range, the magnetic induction intensity changes sharply with temperature changes and is used to manufacture magnetic shunt compensation components in electromagnetic circuits and permanent magnet circuits, etc.
1J38 alloyis usually used for magnetic shunt temperature, compensation components, or temperature sensing components in traveling wave tubes, magnetrons, wind direction and ventilation meters, voltage regulators, mileage speedometers, gasoline meters, electricity meters, etc. that use permanent magnets...
1J38is an iron-nickel-chromium alloy containing about 13% Cr. The addition of a large amount of chromium reduces the Curie temperature and magnetic induction intensity of the alloy, and also increases the resistivity and hardness of the alloy. The Curie and magnetic-temperature characteristics of the alloy have a significant impact on composition fluctuations. The sensitivity is lower than that of iron-nickel binary alloy, so it is easier to control, and there is no irreversible low-temperature change. Its operating temperature range is -40~60℃, and it is mainly used in electric meters and automobile instrument components.
The manufacturing process of stainless steel and alloys involves multiple steps to transform raw materials into flat,rectangular sheets or plates made of stainless steel and alloys. Here are a few key steps for stainless steel and alloys:
Molten stainless steel and alloys are cast into large ingots or billets through a casting process.
During the hot rolling process,the thickness of the steel ingot is gradually reduced and elongated to form long strips or coils.
Annealing involves heating stainless steel and alloys to a specific temperature and then slowly cooling it.
Cold rolling is carried out through rolling mills to reduce thickness to meet customer specifications.
