Forge Pressing Technology for stainless steel:
heating process of preform
Stainless steel forge pressing is a widely used technology for manufacturing parts for various industries, such as automotive, aircraft, financial services and medical devices. Forge pressing is a work hardening process that involves subjecting a piece of metal to high temperature and then using powerful hydraulic press machines to shape it into the desired shape. Stainless steel is the most commonly used material for forge pressings due to its excellent corrosion resistance and its ability to maintain its strength and integrity even in the most extreme conditions.
In stainless steel forging, the preform is first heated in an electric furnace to the temperature required for forging. The heated preform is then placed on a die or a similar tooling and subjected to compression load, usually with a hammer or a die press. The force of this compression load forces the stainless steel to flow into the die cavities and change shape. This is then followed by a cooling process, where the steel is cooled rapidly to prevent it from becoming brittle. The surface of the forged part then needs to be machined and polished to get a desired finish.
Once the forge pressing is complete, the parts are inspected for flaws and defects and then subjected to a variety of tests to ensure that they possess the required properties. These tests include tensile strength tests, hardness tests, stress corrosion cracking tests, fatigue tests, creep tests and oxidation tests. After the tests, the parts may require further processing such as blasting, cutting, welding or soldering.
Stainless steel forge pressed components show better abrasion and wear resistance than castings, which makes them well-suited for applications that require parts with high surface hardness and impact strength. This also means that stainless steel forge pressed components cost less than castings and require less time for production.
The forge pressing technology for stainless steel offers several advantages over other manufacturing processes. It offers a high degree of accuracy, improved surface finish and better strength and durability. It also reduces the risk of defects arising from the manufacturing process, as the number of components produced at one time increases, the cost of production is lowered. In addition, forge pressing for stainless steel produces components that are much more resistant to corrosion and vibration, which makes them perfect for use in corrosive and hostile environments.
