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.
A pharmaceutical equipment factory in Binhai, Tianjin, has long purchased stainless steel forgings for stirring shafts, valve components, and reactor connectors in pharmaceutical equipment. The factory has high requirements for corrosion resistance, hygiene grade, and dimensional stability of forgings, meeting GMP certification and frequent cleaning and disinfection requirements.
This customer encountered the following issues during the initial procurement phase: some forgings had loose internal structures, with visible microcracks appearing after machining; Large dimensional tolerance fluctuations between different batches lead to repeated repairs during assembly; Unstable delivery cycles often affect the overall production line upgrade progress due to forging delays. In addition, customers are concerned that long-term contact with chemical solutions may cause pitting or stress corrosion of stainless steel, affecting equipment lifespan and drug safety.
To address these pain points, we provide customers with customized stainless steel forging solutions. The material is austenitic stainless steel (such as 304L, 316L), with strict control over carbon content and inclusion grades to enhance the substrate's corrosion resistance; The forging process uses multi-directional repeated upsetting to refine grains and eliminate internal looseness and crack tendencies. At the same time, precision molds and constant temperature forging are introduced to keep dimensional tolerances within ±0.3mm, reducing subsequent machining allowances. Each batch of forgings undergoes ultrasonic testing and spectral composition analysis, and traceability reports are issued to meet the pharmaceutical industry's requirements for material consistency. In terms of production scheduling, we reserved an emergency order channel, reducing regular delivery times by 15% to help customers complete equipment upgrades on schedule.
