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 chemical valve parts factory in Baoding, Hebei, has set strict requirements for the comprehensive performance of stainless steel forgings when producing key valve components. The company specializes in chemical fluid control equipment, and its valve fittings must operate normally over long periods in high-temperature, high-pressure, and corrosive media. After extensive selection, the factory ultimately established a partnership with Jianing Forging, entrusting them with supplying matching stainless steel forging products.
The customer discovered the following issues in the original supply system: First, some forgings had internal defects such as looseness and microcracks, causing valve leakage during pressure testing; Second, the grain size grade of the forging is unstable, affecting corrosion resistance and fatigue life; Third, the dimensional consistency of forgings processed by traditional methods is poor, resulting in large machining allowances and a high defect rate. These issues directly led to frequent production line shutdowns and adjustments, rising maintenance costs, and making it difficult to meet the stringent delivery standards of upstream chemical enterprises.
To address these pain points, Jianing Forging offers a systematic solution: selecting high-quality domestic austenitic stainless steel bars as raw materials, which help keep chemical components pure and contain low inclusions; By adopting multi-directional forging + temperature and cooling control, the internal structure of the forgings is dense, with grain size stabilized above grade 6, improving corrosion resistance and fatigue resistance; Through fine mold design and die forging, forging dimensional tolerances can be controlled within ±0.3mm, reducing machining allowance. In addition, Jianing Forging provides third-party non-destructive testing reports and mechanical performance reports for each batch, combined with a raw material traceability system, helping customers achieve full-process quality control from raw materials to finished products. Since the cooperation began, the customer's valve fittings qualification rate has increased to over 98%, and maintenance costs have dropped by about 30%.
