1J116 soft magnetic alloy

Corrosion-resistant soft magnetic alloy 1J116 has high saturation magnetic induction and Curie temperature, high resistance to corrosion in active media with high humidity, and is suitable for various magnetic conductors of various electromagnets working in corrosive media without a protective layer.

Effect of repeated heat treatment on magnetic and mechanical properties of 1J116 material Fe-Cr corrosion-resistant soft magnetic alloy 1J116 is the most widely used soft magnetic alloy in aerospace products, and is used in a large number of solenoid valves working in water and gas, oxidizing media and hydrazine and other active media. The vacuum annealing process is used in the production of the parts to achieve the required magnetic properties, but some of the furnace batch materials after a vacuum annealing process, the magnetic properties are not qualified, and repeat heat treatment is required. But repeat heat treatment and material magnetic properties and mechanical properties of the corresponding relationship and repeat heat treatment on the magnetic properties of the material and mechanical properties have no adverse effects is a problem to be studied. The experiments show that the repeated heat treatment does not adversely affect the performance of 1J116 material, but can significantly reduce the coercive force of Guo, and can produce a certain degree of increase in the magnetic induction strength B240. At the same time, the repeated heat treatment does not cause any deterioration of the mechanical properties of 1J116 material. On the contrary, it increases the plasticity level of the alloy to a certain extent, which is more favorable for its use. Effect of carbon content on the magnetic properties of corrosion-resistant soft magnetic alloy 1J116 Corrosion-resistant soft magnetic alloy 1J116 is used as a material for solenoid valves operating in oxidizing and hydrazine type media. It has a higher saturation magnetic susceptibility and Curie temperature than PoMo alloys and is highly resistant to corrosion in high humidity, seawater conditions and many reactive media; it is suitable for an increasingly wide range of applications in various control systems, armature and solenoid magnetic conductors, wind and hydraulic valve magnetic conductors working in wet and aggressive media without protective layers. In order to effectively control the magnetic properties of the alloy and to ensure the quality of the product parts, the influence of the chemical elemental ratio (especially the carbon content) on the magnetic properties of the alloy needs to be studied so that measures can be taken to control the elemental content to achieve satisfactory magnetic properties of the parts and to meet the product requirements. Studies have shown that the elemental content has a significant effect on the magnetic properties of the material. In the smelting process and heat treatment system under the same conditions, when the C content is less than 0.015%, can significantly improve the magnetic properties of the material. Author:
