ASTM A949 S31803 S31500 S32550 S31200 S31260 Spray-Formed Seamless Ferritic Stainless Steel Pipe for General Purpose

Material

ASTM A949 specifies the requirements for spray-formed seamless ferritic stainless steel pipes. These pipes are designed for general-purpose applications where corrosion resistance and mechanical strength are essential. The spray-forming process enhances the material properties, making it suitable for various industrial applications.

Specification

The specification covers the following grades:

• S31803
• S31500
• S32550
• S31200
• S31260

These grades are characterized by their unique chemical compositions and mechanical properties, making them suitable for different environments and applications.

Key Features

• Corrosion Resistance: Excellent resistance to pitting and crevice corrosion.
• High Strength: Enhanced mechanical properties due to the spray-forming process.
• Versatility: Suitable for a wide range of applications in various industries.
• Seamless Construction: Provides uniformity and reliability in performance.

Chemical Composition

Mechanical Properties

Steel Grade

The steel grades specified in ASTM A949 are designed to meet specific mechanical and chemical property requirements, ensuring their suitability for various applications in industries such as oil and gas, chemical processing, and power generation.

Application

These spray-formed seamless ferritic stainless steel pipes are widely used in:

• Oil and gas exploration and production
• Chemical processing plants
• Power generation facilities
• Marine applications
• Wastewater treatment

Possible Alternative Grades

While ASTM A949 grades are suitable for many applications, alternative grades may be considered based on specific requirements:

• AISI 304: General-purpose stainless steel with good corrosion resistance.
• AISI 316: Offers better corrosion resistance than 304, especially in chloride environments.
• Duplex Stainless Steels: Such as S32205, which provide higher strength and improved corrosion resistance.
