1. Characteristics of Invar 4J36.
As a low expansion alloy, Invar 4J36 has the following properties:
1.Low coefficient of expansion: In the temperature range of -270 to +200, Invar 4J36 has an extremely low coefficient of expansion of only 15×10^-6℃^-1。This means that the dimensional change of Invar 4J36 is very small when the temperature changes, so it can be used as an ideal material for the manufacture of precision instruments and equipment.
2.Good low-temperature performance: At very low temperatures, Insteel 4J36 can still maintain good mechanical properties. It retains high tensile strength and yield strength at low temperatures of -270.
3.Good thermal stability: In the high temperature environment, Yingang 4J36 is not easy to oxidize or corrode, and has good thermal stability.
4.Good machinability: Invar 4J36 is easy to perform cutting, welding and machining operations.
Second, the application field of Yingang 4J36.
Due to the above characteristics, Invar 4J36 is widely used in the following fields:
1.Aerospace field: Due to the extremely low coefficient of expansion and good low-temperature performance of Invar 4J36, it can be used to manufacture precision instruments and equipment in aircraft and satellites. For example, it is used to make key components such as gyroscopes and accelerometers.
2.Nuclear industry: In nuclear reactors and nuclear fuel cycle systems, equipment and components that can operate at extremely low temperatures are required. Invar 4J36 can be used to manufacture these equipment and components, such as nuclear fuel cladding, cryogenic valves, etc.
3.Precision instrument field: Because Invar 4J36 has stable size and good mechanical properties, it can be used to manufacture various precision instruments and equipment, such as optical instruments, measuring equipment, electron microscopes, etc.
4.Cryogenic engineering: In the process of liquefied natural gas (LNG) transportation, storage and utilization, some equipment and components that can work in a low temperature environment are required. Invar 4J36 can be used to manufacture these equipment and components, such as cryogenic pipes, cryogenic storage tanks, etc.
5.Medical device field: Due to the good biocompatibility and corrosion resistance of Indysteel 4J36, it can be used to manufacture medical devices, such as dental implants, surgical instruments, etc.
3. The production process of Yingang 4J36.
The production process of Indy Steel 4J36 mainly includes the following steps:
1.Ingredients: According to the required proportion of ingredients, select the appropriate raw materials for batching.
2.Smelting: The prepared raw materials are smelted at high temperature to form a uniform alloy liquid.
3.Casting: The molten alloy liquid is poured into a mold for casting, forming a casting of the desired shape and size.
4.Heat treatment: Heat treatment is applied to castings to adjust their mechanical and physical properties.
5.Machining: Machining heat-treated castings such as turning, milling, drilling, etc., to obtain the desired size and shape.
6.Inspection: Conduct quality inspection on processed products to ensure that they meet relevant standards and customer requirements.
