We are one of the best ASTM A213 TP321 Tube supplier in India
ASTM A213 Type 321 Seamless Tube and ASME SA213 TP321 ERW Tubes can withstand significant mechanical stress and pressure.
How does the choice of surface finish of Stainless steel 321 tube affects its performance?
| Corrosion Resistance | Smooth finish reduce crevice sites |
|---|---|
| Cleanability & Hygiene | Its much easier to clean smooth surface |
| Oxidation Resistance | used in high-heat applications up to ~900°C |
| Weld Quality | Lack of fusion or cracking |
| Fatigue Resistance | Smooth surface prevents crack initiation |
