The following is a detailed introduction to TP310S bright annealed
stainless steel pipe, covering parameters, standards, advantages,
packaging and application areas:
1. Product introduction
TP310S is a kind of high chromium-nickel austenitic stainless steel
(equivalent to the Chinese grade 0Cr25Ni20), with excellent high
temperature oxidation resistance, corrosion resistance and good
mechanical properties. Bright annealing (BA) is a surface treatment
process that keeps the surface of the steel pipe bright and free of
oxidation by heating and cooling in an oxygen-free environment,
while eliminating internal stress and improving corrosion
resistance and aesthetics.
2. Main parameters
Chemical composition (ASTM A312/A312M standard) :
- Carbon (C) ≤0.08%
- Chromium (Cr) 24-26%
- Nickel (Ni) 19-22%
- Silicon (Si) ≤1.0%
- Manganese (Mn) ≤2.0%
- Phosphorus (P) ≤0.045%
- Sulfur (S) ≤0.03%
Mechanical properties:
- Tensile strength: ≥515 MPa
- Yield strength: ≥205 MPa
- Elongation: ≥35%
Size range:
- Outer diameter: 6mm ~ 530mm (can be customized according to demand)
- Wall thickness: 0.5mm ~ 30mm
- Surface treatment: bright annealing (BA), surface roughness
Ra≤0.4μm.
3. Standards of TP310S Stainless Steel Pipe
- ASTM A312/A312M (Seamless/Welded Austenitic Stainless Steel Pipe)
- ASTM A269 (Universal Seamless and Welded Stainless Steel Pipe)
- ASTM A213 (Stainless Steel Tubes for Boilers and heat exchangers)
- EN 10216-5
- GB/T 14976, GB/T 13296
4. Product advantages
- High temperature resistance: can be used continuously below 1150℃,
excellent antioxidant performance.
- Corrosion resistance: High chromium-nickel content makes it
resistant to acid and alkali, sulfide corrosion, suitable for harsh
environments.
- Smooth surface: BA treatment avoids oxidation, no secondary
polishing, suitable for precision equipment or food grade
applications.
- Stable mechanical properties: annealing process eliminates
processing stress, improves ductility and fatigue resistance.
- Long life: Low maintenance costs, suitable for long-term high
temperature or corrosive environments.
5. Packing method
Conventional packaging:
- Single or multiple bindings, both ends of the plastic sheath
anti-collision.
- Coated with waterproof paper or plastic film, wooden/iron case
reinforcement (export standard).
Special requirements:
- Vacuum packing (anti-oxidation requirement).
- Woven bag or pallet packing (bulk transport).
6. Application field
- High temperature equipment: boiler, heat exchanger, heating furnace
tube, cracking furnace tube.
- Chemical industry: acid, alkali medium transport pipeline,
petrochemical reaction vessel.
- Food and medicine: sterile pipes, fermentation equipment (in line
with FDA/GB 4806.9 standard).
- Environmental energy: flue gas desulfurization (FGD) system,
nuclear power auxiliary equipment.
- Decoration field: high-grade building curtain wall, handrail
(bright surface beautiful).
Additional description
Selection recommendation: If used in a strong reducing acid
environment (such as hydrochloric acid), it is necessary to
evaluate whether further corrosion resistance treatment is
required.
Certification support: Third-party test reports (e.g. SGS, BV) or
material certificates (MTC) can be provided.
