Understanding SA-240/SB463, A240/B 463
What It Is:
These two standards work in tandem to guarantee a product that is both materially superior and hygienically sound.
- SA-240: This is the master specification for the N08904 (904L) plate itself, dictating its unique chemical composition—including high levels of nickel, molybdenum, and copper.
- SB463: This is the definitive standard for sanitary tubing, governing the manufacturing process, surface finish (Ra), cleanliness, and testing required to produce a hygienic, contamination-free final product.
- A Certified Combination: We start with fully certified SA-240 material to create a sanitary tube that meets or exceeds all SB463 requirements.
Why It Is Your Core Focus:
Our strict adherence to both standards is our promise of delivering a robust, reliable, and pure solution for your critical systems.
- It guarantees superior performance against moderately to highly corrosive media where 316L would be inadequate, especially in the presence of sulfuric acid.
- It ensures an ultra-smooth, crevice-free internal surface that minimizes bio-burden and allows for effective, repeatable Clean-in-Place (CIP) cycles.
- This dual certification simplifies your validation process with fully traceable materials and comprehensive MTCs, essential for regulated industries.
