read moreForging is a processing method that uses forging machinery to exert pressure on metal blank to produce plastic deformation to obtain forgings with certain mechanical properties, certain shape and size. It is one of the two components of forging (forging and stamping). Forging can eliminate the defects such as as as cast porosity in the smelting process and optimize the microstructure. At the same ...
The reasons for insufficient hardness of forgings caused by improper post forging heat treatment process are: Quenching temperature is too low; Quenching heating time is too short; Tempering temperature is too high; Severe decarburization of forging surface caused by repeated heating; Unqualified chemical composition of steel, etc. Forging the reasons for the high hardness of forgings caused by im...
The recrystallization temperature of steel is about 460 ℃, but 800 ℃ is generally used as the dividing line, and hot forging is higher than 800 ℃; The temperature between 300 ℃ and 800 ℃ is called warm forging or semi hot forging. Forging can be divided into cold forging and hot forging according to the temperature of the blank during processing. Cold forging is generally processed at room tempera...
The main inspection methods of forgings IATF16949:2016 certified forging manufacturer The main inspection methods of forgings are as below: Chemical composition analysis Mechanical property test Low magnification test Metallographic high magnification inspection and NDT. Chemical composition analysis The general chemical composition analysis is mainly the content of carbon, manganese, silicon, sul...
Hot forging dies are mainly used to manufacture dies for pressure processing of workpieces under high temperature conditions, such as hot forging dies, hot extrusion dies, die-casting dies, hot upsetting dies, etc. The commonly used hot work die materials are alloy die steels with medium and high carbon content and alloy elements such as chromium, tungsten, molybdenum and barium. Hot forging dies ...
Guangzhou Forging Factory I Co., Ltd. is the largest free forging high-tech enterprise in South China, with an annual output of 40 000 tons of forgings. In recent years, relying on the professional advantages and R & D strength accumulated in the forging field, the company has accelerated its entry into the middle and high-end forging market. From January to July this year,...
Precision forging is a process that can produce forgings with high surface quality and dimensional accuracy. Due to the high strength and good toughness of the parts manufactured by the forging process, they are suitable for mass production, so nearly 60% of the parts on the automobile are forged. In recent years, with the rapid growth of automobile production, the integration of parts is also in ...
During the heat treatment of forgings, due to the large power of the heating electric furnace and the long holding time, the energy consumption in the whole process is huge. For a long time, how to save energy during the heat treatment of forgings has always been a problem. The so-called "zero heat preservation" quenching refers to the heat treatment process of quenching and cooling immediately wi...
Depending on the forming temperature steel forging can be divided into: Hot forging of steel Forging temperatures above the recrystallization temperature between 950–1250 °C Good formability Low forming forces Constant tensile strength of the workpieces Warm forging of steel Forging temperatures between 750–950 °C Less or no scaling at the workpiece surface Narrower tolerances achievable...
Often known as “impression die forging”, closed die forging involves two or more dies containing impressions brought together. The closed die forging process offers some distinct advantages over many forms of casting or open die forging from a manufacturing standpoint. · Closed die forging usually supplies a more cost-effective process than open-die forging for the fulfillment of high vo...
The inspection methods for forged parts include chemical composition analysis, mechanical property test, low magnification inspection, metallographic high magnification inspection and nondestructive testing. Chemical composition analysis The general chemical composition analysis mainly includes the content of carbon, manganese, silicon, sulfur and alloy elements. The forgings shall be sampled from...
