Ring forgings: Commonly used in food processing equipment (such as annular flanges for fermentation tanks), medical devices (sealing rings for sterilizers), and annular joints for water pipes in civil buildings, etc., due to their resistance to general corrosion and low cost.
Free forgings: Suitable for manufacturing structural parts working at room temperature, such as cylinder bodies of pressure vessels, pipe elbows, valve bodies, etc., and they perform stably, especially in environments that do not come into contact with high-concentration chloride ions.
