In the field of environmental equipment manufacturing, the reliability and durability of key components directly affect the operational efficiency and maintenance costs of the entire system. An environmental protection equipment factory in Datong, Shanxi, has long faced the pain points of insufficient lifespan and frequent maintenance of stainless steel forgings under high temperature and corrosive media conditions. After multiple comparisons, the factory chose to cooperate with Caring Forging, successfully solving the failure problem of existing components through customized stainless steel forging solutions, thereby extending the continuous operation cycle of the equipment.

Customer pain points

The stainless steel forgings originally used by this environmental protection equipment factory exhibited failure phenomena such as intergranular corrosion, stress corrosion cracking, and fatigue fracture in corrosive environments such as high temperature, high humidity, sulfur content, and chloride content. The average replacement cycle is less than 3 months, and each downtime for maintenance causes production losses exceeding five times the cost of purchasing a single batch of forgings. At the same time, suppliers have unstable control over the machining accuracy of complex special-shaped parts, resulting in additional adjustments during assembly and extending delivery cycles. The plant urgently needed a forging product with stable material performance, reliable machining precision, and optimized coordinated corrosion resistance and high-temperature resistance.

Product advantages

To address customer pain points, Jianing Forging, based on years of stainless steel forging experience, has proposed comprehensive solutions:

• Material optimization: Selected austenitic/duplex stainless steel suitable for environmentally friendly equipment conditions, with microalloying treatment to enhance resistance to intergranular corrosion.
• Forging process control: Using multi-directional forging and temperature-controlled forging technologies to refine grain structure, eliminate forging defects, and maintain structural stability of components at high temperatures.
• Fine Machining: Equipped with a five-axis CNC machining center, it enables one-time clamping and forming of complex and irregular parts, with dimensional tolerances controlled within ±0.05mm, eliminating the need for customers to reassemble parts.
• Full-process inspection: From raw material entry to finished product shipment, ultrasonic testing, mechanical property tests, and salt spray corrosion tests are performed, helping each forging meet design service life requirements.

With this solution, the replacement cycle for stainless steel forgings at this environmental equipment factory has been extended from 3 months to over 18 months, with overall equipment efficiency improved by over 40% and long-term operation and maintenance costs reduced by about 60%. With reliable products and timely technical support, Jianing Forging has become a long-term trusted partner for its customers.
