Applications:

• Chemical Processing: Acid processing plants, phosphoric acid production.
• Petroleum Refining: Piping systems and heat exchangers.
• Marine Environment: Components exposed to seawater.

Composition and Properties of 201 Stainless Steel:

ASTM 201 stainless steel is an austenitic stainless steel that offers good mechanical properties and corrosion resistance at a lower cost compared to other grades.

Composition:

• Chromium (Cr): 16-18%
• Nickel (Ni): 3.5-5.5%
• Manganese (Mn): 5.5-7.5%
• Carbon (C): ≤ 0.15%
• Silicon (Si): ≤ 1%
• Phosphorus (P): ≤ 0.06%
• Sulfur (S): ≤ 0.03%
• Nitrogen (N): ≤ 0.25%

Properties:

• Corrosion Resistance: Good resistance to corrosion in mild environments.
• Mechanical Strength: High strength and good formability.
• Cost-Effective: More affordable than other austenitic grades.

Applications:

• Automotive: Trim and molding.
• Household Appliances: Sinks, cooking utensils.
• Structural Applications: Decorative applications and building materials.

General Characteristics of Welded Stainless Steel Pipes:

• Durability: Welded pipes are strong and durable, suitable for various pressure applications.
• Smooth Surface Finish: Provides an aesthetically pleasing appearance and reduces the risk of contamination.
• Versatility: Available in various sizes and specifications to meet diverse application needs.

Standards and Specifications:

• ASTM A312: Standard specification for seamless, welded, and heavily cold worked austenitic stainless steel pipes intended for high-temperature and general corrosive service.

Summary:

ASTM round stainless steel pipes made from grades 321, 904L, and 201 are versatile and reliable materials for various industrial and commercial applications. Each grade offers unique properties, making them suitable for specific environments and purposes. Grade 321 is ideal for high-temperature applications, 904L for aggressive corrosive environments, and 201 for cost-effective solutions in less demanding conditions. Their excellent corrosion resistance, mechanical properties, and versatility make them a preferred choice in many industries.
