Ring forgings: Widely used in marine engineering (such as marine propeller shaft collars, annular components of seawater desalination equipment), chemical industry (reactor flange rings), nuclear industry pipeline rings, etc., which are required to withstand scenarios involving seawater, salt spray, and acid-alkali solutions.
Free forgings: Used in the manufacture of heavy-duty components with strong corrosion resistance, such as high-pressure vessels for the chemical industry, cylinder bodies of bleaching equipment in the papermaking industry, bridge bolts in coastal areas, etc. Their service life in high-temperature, high-humidity environments containing chloride ions is significantly better than that of F304.
