ASME / ANSI B16.5 SS 321 Flanges Manufacturer, UNS S32100 Weld Neck Flange, ASTM A182 F321 Slip-on Flange, WNR 1.4541 Lap Joint Flange, Grade 321 Blind Flange
Stainless steel 321 flange is a type of flange made from the alloy 321 stainless steel. This alloy is a stabilized version of stainless steel 304, which contains titanium to prevent carbide precipitation during welding. The titanium also gives the alloy excellent resistance to intergranular corrosion.
Stainless steel 321 flanges are commonly used in high-temperature applications, such as in the aerospace industry, chemical processing, and power generation. They are also used in applications where resistance to corrosion is critical, such as in the food and pharmaceutical industries.
Stainless steel 321 flanges come in various sizes, shapes, and pressure ratings to suit different applications. They can be manufactured to standard specifications, such as ASME B16.5 or ASTM A182, or customized to meet specific requirements. The flanges can be welded or screwed onto pipes or fittings to create a tight seal.
Overall, stainless steel 321 flanges are a reliable and durable solution for high-temperature and corrosive applications.

Q: What is 321 stainless steel used for?
A: 321 stainless steel is commonly used in various applications where high temperature resistance is required. It is particularly suitable for use in environments with intermittent exposure to temperatures up to 800-1500°F (427-816°C). Some common uses include exhaust systems, aircraft components, furnace parts, and chemical processing equipment.
Q: What is 321 stainless steel equivalent to?
A: The equivalent materials to 321 stainless steel are ASTM A240/A240M and ASME SA-240/SA-240M specifications. These specifications provide the standards for the chemical composition, mechanical properties, and other relevant characteristics of the steel.
Q: What is the difference between 321 and 316L stainless steel?
A: While both 321 and 316L stainless steel are austenitic stainless steels, they have some differences in their composition and properties. The key difference lies in their respective alloying elements. 321 stainless steel contains titanium, which stabilizes the material against chromium carbide precipitation during high-temperature exposure. On the other hand, 316L stainless steel contains molybdenum, which enhances its corrosion resistance, especially in chloride environments. Additionally, 316L stainless steel has slightly higher tensile strength and better resistance to pitting and crevice corrosion compared to 321 stainless steel.
Q: What is 321 steel specification?
A: The specification for 321 stainless steel is defined by ASTM A240/A240M and ASME SA-240/SA-240M. These specifications outline the chemical composition, mechanical properties, heat treatment requirements, and other characteristics of the steel, ensuring its suitability for various applications. It is important to refer to these specifications to obtain detailed information about 321 stainless steel’s specific requirements and limitations.
