Project Background

During the production line upgrade, a heavy food factory in Zhuzhou, Hunan, faced the issue of frequent replacement of key equipment support components. Original ordinary carbon steel forgings corrode severely in humid and acid-alkali alternating food processing environments, not only affecting production continuity but also posing hidden food safety risks. The plant required a forging solution that combined relatively high strength and corrosion resistance to support continuous equipment operation.

Customer pain points

Food processing environments require extremely high corrosion resistance for metal materials. After the customer's original forgings came into contact with acidic cleaning agents, salt solutions, and high-temperature steam, surface pitting and intergranular corrosion occurred, leading to seal failure and equipment shutdown. At the same time, forgings must bear significant mechanical loads, making it difficult to balance strength and toughness in ordinary stainless steel, and frequent breakage further increases maintenance costs and losses from production line downtime. Customers urgently need a forging that meets hygiene standards, is corrosion-resistant, and has relatively high strength, with high machining precision, smooth and easy-to-clean surfaces, and prevents microbial growth.

Product advantages

Jianing Forging addresses customer pain points by using high-quality stainless steel billets and employing fine forging processes and optimized heat treatment processes to produce stainless steel forgings that meet the hygiene requirements of the food industry. The specific advantages are as follows:

• Material optimization: Selected 316L or equivalent corrosion-resistant stainless steel, effectively resisting corrosion from chlorides and acidic and alkaline media, extending service life.
• Mechanical performance improvement: Through reasonable forging ratios and temperature-controlled forging, the internal structure of the forging becomes dense, and its tensile strength and impact toughness meet the requirements of heavy-duty conditions.
• Surface treatment: Uses a fine polishing process after machining, with a surface roughness of Ra≤0.8μm, easy to clean and free of dirt and dirt.
• Customized services: Based on customer equipment interfaces and stress conditions, we provide integrated solutions for non-standard dimensions and special-shaped forgings to reduce assembly errors.

After the delivery of this batch of stainless steel forgings, the customer's production line continuously operated more smoothly, maintenance frequency dropped sharply, and the company successfully passed the hygiene audit in the food industry, earning high recognition from the customer. Jianing Forging will continue to provide reliable stainless steel forging solutions for the heavy food industry sector.
