Understanding SB-168, B 168, 5540
What It Is:
These standards work together to ensure a product that is both materially superior and hygienically sound.
- SB-168: This is the master specification for the N08800 (Incoloy 800) alloy plate, dictating its unique chemical composition, including high levels of nickel, chromium, and iron.
- B 168: This is the definitive standard for nickel-chromium alloy plates, governing the manufacturing process, surface finish (Ra), cleanliness, and testing required to produce a contamination-free final product.
- 5540 Stainless Steel Seamless Tube: A certified combination that starts with fully certified SB-168 or B 168 material to create a seamless tube meeting or exceeding all 5540 requirements.
Why It Is Your Core Focus:
Our strict adherence to these standards promises a robust, reliable, and pure solution for your critical systems.
- It guarantees superior performance against moderately to highly corrosive media where standard alloys would be inadequate, especially in the presence of acidic environments.
- 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.
