Heat-resistant Steel Frame1.4849
1.4848 and 1.4849 are stainless heat resistant steel and heat resistant alloy steel materials for casting respectively, with the following characteristics:
-High temperature resistance: These two materials can maintain high strength and corrosion resistance in a high temperature environment.
-Antioxidant properties: 1.4848 Material has good antioxidant properties at high temperature and is not easy to be eroded by oxides.
-Thermal expansion performance: these two materials have a low thermal expansion coefficient at high temperature, which can reduce the deformation problem caused by temperature changes.
Applications in precision casting
1.4848 and 1.4849 materials have been widely used in the precision casting of heat treatment material basket and material tray, and the main reasons are as follows:
-High temperature resistance: in a high temperature environment, the heat treatment material basket and material plate need to withstand high temperature and pressure, and these two materials can meet this demand.
-Antioxidant performance: at high temperature, oxides are easy to attach to the surface of the material, reducing the performance of the material basket and material plate.1.4848 The good antioxidant properties of the material can effectively prevent this problem.
-Thermal expansion performance: In a high-temperature environment, the thermal expansion coefficient of materials is an important consideration. The low thermal expansion coefficient of these two materials can ensure the dimensional stability of the material basket and material plate at high temperature.
In the precision casting of heat treatment material basket and material plate, strict process control is required to ensure the quality and performance of products.
-Material selection: 1.4848 and 1.4849 The temperature, pressure and corrosion of the used environment and the requirements of the product.
-Casting process: During the casting process, the melting temperature, casting temperature and cooling speed need to be reasonably controlled to ensure the uniformity and density of the material.
-Heat treatment process: select the appropriate heat treatment process, such as annealing, quenching and tempering, to improve the mechanical properties and heat resistance of the material.
