In the production of hot forging, the selection and application of metal materials is a crucial link. The right material selection can ensure the quality and performance of the forging, while affecting the production cost and process route. This paper will discuss the selection principle of metal materials, common materials and application precautions in hot forging forging production.
In the production of hot forging, the selection of metal materials should follow the following principles:
Meet the performance requirements: according to the use of forgings and working conditions, select metal materials with appropriate mechanical properties, physical properties and chemical properties.
Process feasibility: Consider the malleability, plasticity and deformation capacity of the metal material during hot forging, as well as its sensitivity to process parameters (such as temperature and pressure).
Economy: Under the premise of ensuring quality and performance, select metal materials with moderate cost and abundant resources to reduce production costs.
Common metal materials
Carbon steel: Carbon steel is one of the most commonly used hot forging materials, with good malleability and strength, suitable for the manufacture of various mechanical parts and structural parts.
Alloy steel: Alloy steel by adding alloying elements (such as manganese, silicon, chromium, etc.) to improve the mechanical properties and corrosion resistance of steel, widely used in automotive, aerospace and other fields.
Non-ferrous metals: such as aluminum alloy, copper alloy, etc., with low density and good electrical and thermal conductivity properties, are widely used in aerospace, electronics industry and other fields.
Application precautions
Material quality control: to ensure that the selected metal materials meet the relevant standards and requirements, chemical composition analysis, mechanical properties test and other tests to ensure material quality.
Process parameter optimization: For different metal materials, optimize the hot forging process parameters, including heating temperature, deformation rate, cooling mode, etc., in order to obtain good forging organization and performance.
Environmental protection and sustainability: When choosing metal materials, environmental protection and sustainability factors should be considered, renewable and recyclable materials should be selected as far as possible, and energy consumption and waste emissions in the production process should be paid attention to.
With the continuous development of science and technology, new metal materials will continue to emerge. In the future production of hot forging, attention should be paid to the research and application of new materials, such as high-strength lightweight alloys and nanomaterials. At the same time, with the help of advanced numerical simulation and process technology, the efficient use of metal materials and precision forming are realized, and the hot forging forging production is promoted to higher quality, lower cost and more sustainable development.
