DIN11851 FAQS

1. How to Choose Between 304 and 316L Stainless Steel for DIYE DIN11851 Unions?

The selection is mainly based on the corrosiveness of working conditions and hygiene requirements: ① For conventional working conditions (food & beverage, dairy products, non-corrosive media such as water, fruit juice, milk), 304 stainless steel is recommended. It features high cost-performance ratio and fully meets GMP and FDA hygiene standards. ② For highly corrosive and high-hygiene conditions (pharmaceutical, fine chemical industry, media such as medicinal liquid, corrosive cleaning fluid), 316L stainless steel is the priority choice. With a molybdenum content ≥ 2%, it boasts superior intergranular corrosion resistance and acid-alkali resistance, can pass the 1000-hour salt spray test, has a longer service life, and meets the demands of high-end aseptic production. For customized selection advice, please contact the DIYE technical team with detailed working condition information.
