Hazen Williams C: stainless_steel_304_316
Hazen-Williams roughness coefficients (C values) for pressure pipe hydraulic calculations. Covers new and aged pipe materials: ductile iron (cement-lined/unlined), cast iron at 0/5/10/20/30/40 years, carbon steel (new/corroded/lined), copper, brass, PVC, HDPE, CPVC, FRP, concrete, asbestos cement, galvanized steel, stainless steel, lead, vitrified clay. Includes AWWA M31 and NFPA 13 design C values. C value ranges (min/typical/max) and recommended design values are provided.
| pipe material | pipe condition | c value max (dimensionless) | c value min (dimensionless) | c value typical (dimensionless) | design c value (dimensionless) | notes |
|---|---|---|---|---|---|---|
| stainless_steel_304_316 | aged | 150 | 140 | 145 | 145 | Maintains C over time in corrosion service; no tuberculation; essentially same as new |
| stainless_steel_304_316 | new | 150 | 140 | 145 | 145 | Smooth austenitic stainless bore; used for aggressive process fluids, food, pharma; no corrosion in most services |
