304 Stainless Steel Pipe Advantages:Comparative Analysis of TP304, SS304 & AISI304

‌1. Material Standards & Composition‌

TP304 (ASTM/ASME), SS304 (JIS SUS304), and AISI304 (SAE 304) are interchangeable grades with minor regional certification variations‌. All three share a base composition of ‌18–20% Cr‌ and ‌8–12% Ni‌, ensuring oxidation resistance and ductility‌. Carbon content is strictly controlled (≤0.08% for TP304/AISI304; ≤0.07% for SS304) to minimize carbide precipitation during welding‌.

‌2. Mechanical & Thermal Performance‌

All grades exhibit ‌≥520 MPa tensile strength‌ and ‌≥205 MPa yield strength‌, suitable for high-pressure piping system. SS304 shows marginally higher elongation (≥40%) due to JIS-standardized processing‌. Thermal stability extends to ‌800°C‌, ideal for heat exchangers and exhaust components‌.

 

‌Figure 1: Yield Strength vs. Temperature‌

![Yield strength retention up to 500°C]

 

‌3. Key Advantages‌

‌① Corrosion Resistance‌

Chromium oxide passivation layers provide immunity to oxidation, weak acids, and organic compounds‌12. All grades resist stress corrosion cracking in chloride-free environments‌. For marine applications, TP304L (C≤0.03%) is recommended‌.

 

‌② Formability & Weldability‌

Cold/hot working (e.g., bending, stamping) is feasible without cracking‌16. TIG/MIG welding produces defect-free joints, maintaining corrosion resistance post-welding‌.

 

‌③ Hygienic Properties‌

Electropolished surfaces inhibit bacterial growth, critical for food processing and pharmaceutical pipelines‌.

 

‌④ Cost Efficiency‌

SS304 costs 5–8% less than TP304 due to Japan’s centralized production‌. AISI304 remains economical for low-pressure industrial components‌.

 

‌4. Application Scenarios‌

IndustryPreferred GradeUse Case
‌Chemical Processing‌TP304Acid transport pipelines‌
‌Construction‌SS304Structural supports‌
‌Food & Beverage‌AISI304/TP304Sanitary tubing‌
‌Oil & Gas‌TP304High-pressure manifolds‌

 

‌5. Limitations & Alternatives‌

‌Chloride exposure‌ (>50 ppm) causes pitting corrosion; switch to 316L for marine use‌.

‌Reducing acids‌ (e.g., sulfuric acid) require duplex stainless steels‌.

‌Conclusion‌

TP304, SS304, and AISI304 stainless steel pipes deliver interchangeable performance with region-specific certification advantages‌. Their balanced strength, corrosion resistance, and affordability make them indispensable across industries. For ASTM-compliant projects, prioritize TP304; for cost-sensitive JIS applications, SS304 excels

TP304/ Ss304 Stainless Steel 304 Pipe Excutive Standard:

For 304 stainless steel, the Ni element in its composition is very important, which directly determines the corrosion resistance of 304 stainless steel and its value.
The most important elements in 304 are Ni and Cr, but they are not limited to these two elements.

Specific requirements are specified by product standards. The common judgment in the industry is that as long as the Ni content is greater than 8% and the Cr content is greater than 18%, it can be considered as 304 stainless steel.

This is why the industry calls this type of stainless steel 18/8 stainless steel.

In fact, the relevant product standards have very clear regulations for 304, and these product standards have some differences for different shapes of stainless steel.

Below are some common product standards and tests.

To determine whether a material is 304 stainless steel, it must meet the requirements of each element in the product standard. As long as one does not meet the requirements, it cannot be called 304 stainless steel.

The above four standards are just a few common standards. In fact, there are more than these standards mentioned in ASTM and JIS 304.

In fact, each standard has different requirements for 304, so to determine whether a material is 304, the accurate expression should be whether it meets the 304 requirements in a product standard.

The material certificate generally needs to issue the following types of reports: detailed standard specification comparison: as of 2025-02-08

Historical Evolution of 304 Stainless Steel Pipes: TP304, SS304 & AISI304

‌1. Origins of Stainless Steel‌

The invention of stainless steel traces back to ‌1916‌, when British metallurgist Harry Brearley discovered chromium-enhanced steel’s corrosion resistance while developing rifle barrels‌. This breakthrough laid the foundation for modern austenitic stainless steels like 304‌18. By the ‌1930s‌, the American Iron and Steel Institute (AISI) established standardized grading systems, including ‌AISI 304‌ (18% Cr, 8% Ni)‌.

 

‌2. Development of Regional Standards‌

‌AISI 304‌ stainless steel pipe

AISI 304  became the baseline for industrial applications, with its composition (18-20% Cr, 8-10.5% Ni) ensuring corrosion resistance and formability‌. Its legacy classification persists in non-piping contexts like architectural components‌.

 

‌TP304‌ stainless steel pipe

Introduced under ‌ASTM A312/A213‌, TP304 emerged as the U.S. standard for piping systems, allowing slightly higher nickel (8-11%) for improved weldability in chemical processing‌.

 

‌SS304‌ stainless steel pipe

Japan’s ‌JIS SUS304‌ (SS304) refined carbon control (≤0.07%) to minimize carbide precipitation in welded structures, prioritizing elongation (≥40%) for construction applications‌.

 

‌3. Key Milestones‌

1916Brearley patents chromium steel, marking stainless steel’s birth‌
1930AISI formalizes 304 series with 18/8 Cr/Ni ratios‌
1950ASTM defines TP304 for high-temperature piping systems‌
1980JIS SUS304 gains prominence in Asian construction projects‌

‌Performance Enhancements‌

‌1950s‌: TP304’s ASTM certification enabled use in oil/gas pipelines (≤525°C)‌.

‌2000s‌: SS304’s electropolishing improved hygiene for food/pharma industries‌.

‌5. Global Adoption‌

Global market share by region (2024 data)

‌Americas‌: TP304 dominates due to ASTM compliance in energy sectors.

‌Asia‌: SS304 accounts for 65% of construction projects (JIS G3459)‌.

‌Europe‌: AISI 304 remains prevalent in legacy industrial systems‌.

‌6. Modern Challenges & Solutions‌

‌Chloride corrosion‌: TP304L (C≤0.03%) mitigates pitting in coastal environments‌.

‌Cost pressures‌: SS304’s centralized Japanese production reduces pricing by 5-8% vs. TP304‌.

‌Conclusion‌

From Brearley’s 1916 breakthrough to modern ASTM/ISO certifications, 304 stainless steel pipes (TP304, SS304, AISI304) have evolved through regional standardization and performance optimization‌. Their 18/8 Cr/Ni formula remains a benchmark for durability, corrosion resistance, and cross-industry versatility

Calculating Weight of 304 Stainless Steel Pipes: Formulas and Applications

‌304 stainless steel pipes‌ (TP304, SS304, AISI 304) are widely used in industrial applications due to their corrosion resistance and durability. This article explains the ‌weight calculation formulas‌ for these grades and their regional compliance standards.

 

  1. ‌Basic Weight Formula‌

The weight of a ‌304 stainless steel pipe‌ is determined by its ‌density‌ (7.93 g/cm³) and geometric parameters. The ‌universal formula‌ is:

  • ‌OD‌: Outer diameter (mm)
  • ‌WT‌: Wall thickness (mm)
  • ‌L‌: Length (m)
    This formula simplifies to ‌0.02491 × (OD – WT) × WT × L‌ for quick estimation‌.
  1. ‌Grade-Specific Applications‌

‌TP304 stainless steel pipe(ASTM A312)‌: Dominant in the Americas for energy pipelines due to compliance with ASTM standards‌.

‌SS304 stainless steel pipe (JIS G3459)‌: Preferred in Asian construction projects for its low-carbon formulation‌.

‌AISI 304‌ stainless steel pipe : Retains legacy use in European industrial systems due to compatibility with existing infrastructure‌.

  1. ‌Calculation Example‌

For a stainless steel 304 pipe with ‌OD = 100 mm‌, ‌WT = 10 mm‌, and ‌L = 6 m‌:

Weight=0.02491×(100−10)×10×6=134.5 kgs 

 

  1. ‌Key Influencing Factors‌

‌Wall Thickness‌: A 10% increase in WT raises weight by ~12%‌.

‌Length‌: Weight scales linearly with pipe length‌.

‌Density Variations‌: Minor deviations (e.g., 7.93–7.98 g/cm³) affect precision‌.

‌SS304‌&JIS G3459&nbspStructural frameworks&nbspLower carbon tolerance‌

‌AISI 304‌&EN 1.4301&nbspLegacy chemical plants&nbspNone‌

  1. ‌Practical Considerations‌

Use ‌laser measurement tools‌ to ensure accurate OD and WT inputs‌.

For ‌non-circular pipes‌ (e.g., square or rectangular), adjust the formula using equivalent perimeter calculations‌.

Verify regional standards (e.g., ASTM vs. JIS) to align with material certifications‌.

This guide provides a foundation for calculating weights across TP304 stainless steel pipe, SS304 stainless steel pipe, and AISI 304 stainless steel pipes, ensuring compliance with global engineering requirements. For complex projects, consult ‌ASTM‌ or ‌JIS documentation‌ for grade-specific tolerances‌
