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 ship parts factory in Nanjing, Jiangsu, due to the upgrade needs of key marine components, partnered with Jianing Forging to develop high-quality stainless steel forgings. This batch of forgings will be used in transmission systems in marine environments, setting strict standards for material corrosion resistance, mechanical strength, and dimensional accuracy. Drawing on years of experience in the specialty alloy forging field, Jianing Forging provided this customer with customized solutions.
Customers have long faced three core issues with their existing suppliers: First, ordinary stainless steel forgings experience pitting and stress corrosion cracking after being immersed in seawater, affecting equipment service life; Second, the forming precision of complex special-shaped structural parts (such as flanges and bushings) is insufficient, resulting in large machining allowance and an increased defect rate; Third, performance fluctuations between batches are significant, failing to meet the stability requirements of classification society certification.
To address customer pain points, Jianing Forging has optimized material selection, process design, and quality control: using duplex stainless steel and lower carbon austenitic stainless steel, which has improved resistance to chloride ion corrosion; Using multi-directional forging + temperature control and shape control technology, the forging's flow lines are evenly distributed and dimensional tolerances are kept within ISO IT7 level; Through full-process digital monitoring and third-party testing, it helps ensure stable and consistent mechanical properties and intergranular corrosion test results for each batch. The final delivered forgings were tested by the customer's installation machine, with corrosion resistance life more than three times increased, a processing scrap rate reduced to below 0.5%, and successfully passed the China Classification Society (CCS) product certification.
