ASTM A269 TP310S Stainless Steel Seamless Pipe

ASTM A269 TP310S Stainless Steel Seamless Pipe Bright Annealed Pipe 6 - 50.8mm in 6m Length

Products Specification

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

1. High temperature equipment: boiler, heat exchanger, heating furnace tube, cracking furnace tube.
2. Chemical industry: acid, alkali medium transport pipeline, petrochemical reaction vessel.
3. Food and medicine: sterile pipes, fermentation equipment (in line with FDA/GB 4806.9 standard).
4. Environmental energy: flue gas desulfurization (FGD) system, nuclear power auxiliary equipment.
5. 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.
