Shanxi Jianing Forging can process 304, 304L, 316, 316L stainless steel forgings, with a complete range of real-world cases of stainless steel flanges, shafts, and ring forgings, offering excellent corrosion resistance and suitable for chemical and seawater corrosion protection conditions.
In the Songjiang area of Shanghai, a certain environmental chemical plant has been operating in a highly corrosive and high-temperature environment for long-term use, causing key components (such as the reactor stirring shaft and pipeline flanges) to frequently experience fatigue fracture and corrosion leakage. The factory's original carbon steel forgings had a service life of less than three months, seriously affecting production continuity and increasing maintenance costs due to frequent downtime and part replacements.
The environmental chemical industry has extremely high requirements for corrosion resistance, high-temperature strength, and dimensional accuracy of forgings. The plant faces three core pain points: first, pitting and intergranular corrosion occur in existing forgings in chloride-containing dielectric; Second, creep of materials under high-temperature conditions causes loosening of connectors; Third, the supply cycle for non-standard forgings is long, and quality control for outsourcing is unstable, often resulting in dimensional errors that prevent installation.
To address these issues, Jianing Forging offers customized stainless steel forgings (316L and duplex stainless steel), using multi-directional die forging technology to eliminate internal looseness, combined with solution heat treatment to enhance intergranular corrosion resistance. Products are strictly processed according to drawings, with allowance for precision machining, and third-party flaw detection and inspection help ensure dense and defect-free forgings. By optimizing the forging ratio and molding molds, product dimensional tolerances are controlled within ±0.5mm, better meeting on-site installation requirements.
After adopting stainless steel forgings supplied by Jianing Forging, the continuous operation cycle of the equipment was extended from three months to over eighteen months, with no corrosion or breakage during this period. At the same time, due to high consistency of forgings, on-site installation efficiency improved by about 30%, significantly reducing overall operation and maintenance costs.
