ASTM A312 TP304 is a classic austenitic stainless steel seamless pipe, featuring high corrosion resistance, stable mechanical properties and cost-effectiveness. With seamless forming, it suits -196℃ to 650℃ working conditions, applies to fluid transport and structural support, and complies with ASTM A312 and ASME B36.10M/19M standards.

Core Chemical Composition (Mass Fraction, %)

Element	Content Range/Limit	Core Function
Carbon (C)	≤0.08%	Prevents chromium carbide precipitation at high temperatures and reduces intergranular corrosion risk
Silicon (Si)	≤1.00%	Improves smelting purity and oxidation resistance without affecting matrix toughness
Manganese (Mn)	≤2.00%	Enhances strength and cold working performance, preventing cracking during processing
Phosphorus (P)	≤0.045%	Strictly controls harmful impurities, reduces brittleness, and optimizes corrosion and welding performance
Sulfur (S)	≤0.030%	Reduces hot working cracks and ensures forming quality and corrosion resistance
Chromium (Cr)	18.00%-20.00%	Forms a dense chromium oxide passive film to resist erosion by multiple media
Nickel (Ni)	8.00%-11.00%	Stabilizes the austenitic structure, imparts non-magnetism at room temperature, and improves comprehensive performance

Note: Each batch of products undergoes composition testing by spectral analysis or chemical analysis to ensure material compliance and prevent adulteration. Test reports are available upon request

Key Performance Indicators

Mechanical Properties (Compliant with ASTM A312 and GB/T 228.1-2021 Standards)
Performance Item	Unit	Minimum Requirement	Description
Tensile Strength (T.S)	MPa	≥515	Longitudinally sampled, stable and reliable performance
Yield Strength (Y.S, Rp0.2)	MPa	≥205	Excellent resistance to plastic deformation
Elongation After Fracture (EL)	%	≥40	Good toughness, not easy to crack during cold working
Brinell Hardness (HB)	-	≤201	Uniform hardness, suitable for processing needs
Rockwell Hardness (HRB)	-	≤92	Facilitates on-site rapid testing and evaluation

Corrosion Resistance

Relying on the chromium-nickel alloy passive film, it has excellent basic corrosion resistance, capable of resisting corrosion by atmosphere, fresh water, and weak acid-base media. It contains no heavy metal precipitation and meets food-grade and pharmaceutical-grade requirements. For high chloride ion medium scenarios, the TP316 series is recommended.

Sensitization can be eliminated after solution treatment, and no intergranular corrosion cracks are found in standard tests, ensuring strong corrosion resistance stability.

Processing and Welding Performance

Cold Working Performance: The austenitic structure imparts good cold bending and stamping performance, and the performance can be restored by solution treatment after processing.
Welding Performance: Suitable for conventional welding processes such as TIG and MIG welding. The post-welding performance meets standards, and passivation treatment can be performed for harsh working conditions.
Surface Treatment: Supports pickling, sandblasting, polishing and other processes to meet the cleanliness and appearance requirements of different scenarios.

Dimensional and Precision Indicators (Compliant with ASME B36.10M/19M Standard)
