Comparison of SS304 and SS316 Pipe Specifications

 

Specification	SS304 Pipe	SS316 Pipe
Chemical Composition
Carbon (C)	≤ 0.08%	≤ 0.08%
Silicon (Si)	≤ 1.00%	≤ 1.00%
Manganese (Mn)	≤ 2.00%	≤ 2.00%
Phosphorus (P)	≤ 0.045%	≤ 0.045%
Sulfur (S)	≤ 0.030%	≤ 0.030%
Chromium (Cr)	18.0 - 20.0%	16.0 - 18.0%
Nickel (Ni)	8.0 - 11.0%	10.0 - 14.0%
Molybdenum (Mo)	-	2.0 - 3.0%
Mechanical Properties
Tensile Strength	≥ 515 MPa (75,000 psi)	≥ 515 MPa (75,000 psi)
Yield Strength (0.2% Offset)	≥ 205 MPa (30,000 psi)	≥ 205 MPa (30,000 psi)
Elongation in 50 mm (2 in.)	≥ 40%	≥ 40%
Corrosion Resistance	Good general corrosion resistance in many environments. Susceptible to corrosion in chloride - rich environments.	Superior corrosion resistance, especially in chloride - containing environments such as marine and chemical processing environments, due to the presence of molybdenum.
Heat Resistance	Can withstand continuous service temperatures up to about 870°C (1600°F).	Can withstand similar continuous service temperatures as SS304, but may have better performance in high - temperature, corrosive environments.
Surface Finish	Similar options available, including No. 1 (hot - rolled, annealed and pickled - dull, matte finish), No. 2B (cold - rolled, annealed and pickled - smooth, reflective finish), No. 4 (mechanically polished to a semi - bright finish).	Similar surface finish options as SS304.
Manufacturing Processes	Can be produced as seamless (by piercing a solid billet) or welded (using methods like TIG welding).	Also available in seamless and welded forms, with manufacturing processes similar to SS304.
Applications	Food and beverage industry (storage tanks, piping for food products), architecture (handrails, decorative structures), general industrial applications where corrosion resistance is required.	Marine industry (shipbuilding, offshore platforms), chemical processing (reactors, pipelines for corrosive chemicals), pharmaceutical industry (equipment for drug manufacturing, clean - room piping), where high - level corrosion resistance is crucial.
Cost	Generally less expensive than SS316 due to lower nickel and the absence of molybdenum content.	More costly than SS304 because of the higher nickel content and the addition of molybdenum.

 

The Advantages of Material

 

Advantages of SS304 Pipe

 

• Good Corrosion Resistance: SS304 pipes have excellent resistance to general corrosion in many common environments. They can withstand exposure to water, air, and various mild chemical substances, making them suitable for a wide range of applications.
• High Strength and Ductility: With a tensile strength of at least 515 MPa and an elongation of at least 40%, SS304 pipes offer a good combination of strength and ductility. They can withstand significant mechanical stress and can be easily formed and fabricated into different shapes and sizes without cracking or breaking.
• Good Weldability: SS304 pipes can be easily welded using various welding methods such as TIG and MIG welding. This allows for convenient installation and connection in different projects.
• Hygienic and Clean: It has a smooth surface finish, which is easy to clean and is less likely to accumulate dirt, bacteria, or other contaminants. This makes it very suitable for applications in the food and beverage industry, as well as in the pharmaceutical industry.
• Cost - effective: Among stainless steel pipes, SS304 is relatively cost - effective. It provides a good balance between performance and cost, making it a popular choice for many applications where the highest level of corrosion resistance is not strictly required.

Advantages of SS316 Pipe

 

• Superior Corrosion Resistance: The addition of molybdenum gives SS316 pipes outstanding corrosion resistance, especially in chloride - rich environments. They can resist pitting and crevice corrosion better than SS304 pipes, making them ideal for use in marine, chemical, and saltwater applications.
• High Temperature Resistance: SS316 pipes have better high - temperature performance compared to SS304. They can maintain their mechanical properties and corrosion resistance at higher temperatures, making them suitable for applications in high - temperature and corrosive environments.
• Excellent Chemical Resistance: SS316 is more resistant to a wider range of chemicals and acids. It can handle more aggressive chemical substances without significant degradation, which is crucial in chemical processing and pharmaceutical industries.
• Long Service Life: Due to its excellent corrosion and heat resistance, SS316 pipes have a longer service life even in harsh operating conditions. This reduces the need for frequent replacement and maintenance, resulting in lower overall costs in the long run.
• High Quality Appearance: SS316 pipes can achieve a very smooth and shiny surface finish, which is aesthetically pleasing. This makes them suitable for applications where both functionality and appearance are important, such as in architectural and decorative applications.
