Product Description

Product Description

ASTM S32205, 2205, and 2507 are grades of super duplex stainless steel known for their excellent strength, toughness, and corrosion resistance. These grades are commonly used in applications that require high performance in harsh environments. Here's an overview of these stainless steel grades and their characteristics:

Composition and Properties of ASTM S32205 (2205) Super Duplex Stainless Steel:

ASTM S32205 (also referred to as 2205) is a super duplex stainless steel with a balanced austenitic-ferritic microstructure, providing enhanced strength and resistance to corrosion.

Composition:

• Chromium (Cr): 22-23%
• Nickel (Ni): 4.5-6.5%
• Molybdenum (Mo): 3-3.5%
• Carbon (C): ≤ 0.03%
• Manganese (Mn): ≤ 2%
• Silicon (Si): ≤ 1%
• Phosphorus (P): ≤ 0.03%
• Sulfur (S): ≤ 0.02%
• Nitrogen (N): 0.14-0.20%

Properties:

• Corrosion Resistance: Excellent resistance to chloride stress corrosion cracking, pitting, and crevice corrosion.
• Mechanical Strength: Higher yield and tensile strength compared to austenitic and ferritic grades.
• Toughness: Good impact toughness even at low temperatures.

Applications:

• Oil and Gas Industry: Piping systems, heat exchangers, and pressure vessels.
• Chemical Processing: Storage tanks, valves, and pumps.
• Marine Applications: Offshore platforms, shipbuilding, and desalination plants.

Composition and Properties of 2507 Super Duplex Stainless Steel:

2507 (also known as UNS S32750) is a super duplex stainless steel with higher chromium, molybdenum, and nickel content, providing superior performance in extreme environments.

Composition:

• Chromium (Cr): 24-26%
• Nickel (Ni): 6-8%
• Molybdenum (Mo): 3-5%
• Carbon (C): ≤ 0.03%
• Manganese (Mn): ≤ 1.2%
• Silicon (Si): ≤ 0.8%
• Phosphorus (P): ≤ 0.035%
• Sulfur (S): ≤ 0.02%
• Nitrogen (N): 0.24-0.32%

Properties:

• Corrosion Resistance: Superior resistance to pitting, crevice corrosion, and chloride stress corrosion cracking.
• Mechanical Strength: Extremely high tensile and yield strength.
• Toughness: Excellent impact toughness, particularly in harsh environments.

Applications:

• Oil and Gas Industry: Subsea equipment, pipelines, and processing systems.
• Chemical Processing: High-performance equipment exposed to aggressive chemicals.
• Marine Applications: Components exposed to seawater, such as seawater cooling and ballast systems.

General Characteristics of Super Duplex Stainless Steel Pipes:

• High Strength: Super duplex stainless steels provide significantly higher strength compared to standard austenitic stainless steels.
• Corrosion Resistance: Excellent resistance to a wide range of corrosive environments, including chlorides and sulfides.
• Durability: High durability and long service life even in demanding conditions.
• Weldability: Good weldability using standard welding techniques, although some care is required to avoid precipitation of intermetallic phases.

Standards and Specifications:

• ASTM A790: Standard specification for seamless and welded ferritic/austenitic stainless steel pipe.
• ASTM A928: Standard specification for ferritic/austenitic (duplex) stainless steel electric fusion welded pipe.

Summary:

ASTM S32205 (2205) and 2507 super duplex stainless steel round pipes are ideal for use in demanding applications where high strength, excellent corrosion resistance, and durability are required. These materials are extensively used in the oil and gas industry, chemical processing, and marine applications due to their ability to withstand harsh environments and provide long-lasting performance. Their balanced microstructure and superior properties make them a preferred choice for critical applications.
