Tollerance
- →304 SS susceptible to pitting in chloride-containing CIP solutions — 316L required for food contact
- →Surface finish Ra ≤0.8μm required to prevent bacterial harboring in EHEDG-compliant designs
- →Dead zones and crevices in casting geometry create CIP-inaccessible bacterial growth sites
- →FDA 21 CFR and EU 1935/2004 material compliance documentation required for every shipment
- →EHEDG and 3-A Sanitary Standards geometric requirements for hygienic design
±0.30–0.80mm
- 316L stainless steel as standard material for all food contact surfaces — CT4–CT6 tolerance
- Surface finish Ra ≤0.8μm standard; electropolishing available for critical surfaces
- Hygienic design review: dead zone, crevice, and drainage path evaluation before production
- FDA 21 CFR and EU 1935/2004 material compliance documentation with every shipment
- Passivation and electropolishing surface treatment options for EHEDG compliance
* Tolleranze basate sulle norme ISO 8062 / GB/T 6414. I valori effettivi dipendono dalla geometria della parte, dal materiale e dai parametri del processo.
