ASTM A193 / A194 Stainless Steel 321 / 321H Studs

When it comes to fasteners, studs hold a lot of importance. The quality of the stud determines the strength of the entire structure. Stainless steel is a popular material that is used in the production of fasteners. Stainless Steel 321 is a popular material used in exhaust systems, aircraft applications, and other high-temperature environments where corrosion resistance and strength are important. Stainless Steel 321 Stud is a fastener made from this high-quality material. These studs are highly resistant to corrosion and oxidation in high-temperature environments, making them the ideal solution for various industrial applications.

Stainless Steel 321H Stud is another popular type of fastener made from Stainless Steel 321H, an enhanced version of Stainless Steel 321. These studs are used in high-temperature applications where extreme strength is required. They are also used in power generation, oil and gas, and chemical processing industries. Stainless Steel 321H Studs can handle extreme temperatures due to their high carbon content, which helps to improve their overall strength.
Stainless Steel 321 Stud and Stainless Steel 321H Stud have several benefits that make them the ideal choice for industrial applications. Firstly, both studs are highly resistant to corrosion and oxidation, making them perfect for use in high-temperature environments. Secondly, these studs offer excellent strength and can withstand extreme temperatures. Lastly, their unique properties make them easy to manufacture, which results in lower costs.

Stainless Steel 321 stud and Stainless Steel 321H Stud are made using the same stainless steel 321. However, the difference between them lies in the carbon content. The stainless Steel 321H stud has a higher carbon content than Stainless Steel 321 stud, which makes it stronger and more resistant to high-temperature environments. It’s often used in applications that require more strength and durability.
Stainless Steel 321 Stud and Stainless Steel 321H Stud are two fasteners essential in industrial applications. Both studs are highly resistant to corrosion and oxidation, offer excellent strength, and can withstand extreme temperatures. The major difference is the carbon content, with Stainless Steel 321H stud being stronger and more durable.


Stainless Steel 321 Studs are commonly used in applications that require high-temperature strength & corrosion resistance. They are widely used in aerospace, chemical, power generation & thermal processing. Typical applications include fastening components in exhaust systems, furnace equipment, and high-temperature process piping.

Stainless Steel 321H Studs can withstand temperatures up to approximately 900°C (1650°F). They maintain good mechanical properties & oxidation resistance at high temperatures, making them suitable for applications in heat-intensive environments.

The carbon content is the main difference between Stainless Steel 321 and 321H Studs. Stainless Steel 321H contains a higher carbon content compared to 321. This higher carbon content provides improved high-temperature strength and creep resistance, making it suitable for applications that require enhanced performance at elevated temperatures.
