Stainless Steel 321 Stud Bolts are highly valued for their exceptional resistance to high temperatures and corrosion, making them a preferred choice for demanding applications. These stud bolts are produced to meet rigorous industry standards, including ASTM A320, ASME SA320, and DIN 931. Their unique composition and properties suit high-stress environments, such as aerospace, chemical processing, and power generation industries. At Vision Alloys, we ensure our products adhere to these standards to provide reliability and performance in critical applications.
As a specialized stainless steel 321 stud bolt manufacturer, we utilize high-quality 321 stainless steel, an alloy known for its excellent resistance to oxidation and carburization. The typical composition of 321 SS stud bolts includes 17-19% chromium, 9-12% nickel, and a small amount of titanium (around 5 times the carbon content), which enhances the alloy's stability at high temperatures. This composition offers superior resistance to intergranular corrosion, making these stud bolts ideal for use in environments subjected to thermal cycling or elevated temperatures.
Features:
Material:
Stainless Steel 321 is an austenitic stainless steel alloy that contains titanium, which makes it highly resistant to intergranular corrosion and suitable for high-temperature applications.
High-Temperature Resistance:
Stainless Steel 321 is designed to perform well at elevated temperatures, making stud bolts made from this material ideal for applications where heat resistance is crucial.
Corrosion Resistance:
This material offers excellent resistance to corrosion, particularly in environments where there is exposure to acids, alkalis, and other corrosive substances.
Threaded Ends:
Stud bolts are threaded at both ends, allowing them to be screwed into threaded holes, such as those in nuts, flanges, or other fastening components.

What are the Considerations when selecting SS 321 Stud Bolts
Thread Size and Length:
Select the appropriate thread size and length based on the specific application and fastening requirements.
Torque Specifications:
Follow manufacturer-recommended torque specifications to ensure proper tightening and prevent over-tightening, which can lead to stud bolt failure.
Corrosion Protection:
While Stainless Steel 321 is highly corrosion-resistant, additional protective coatings or measures may be necessary in extremely corrosive environments.
Heat Resistance:
Ensure that the stud bolts are used within their specified temperature limits to prevent degradation of the material's properties.
Quality and Inspection:
Regular inspection and maintenance of stud bolts are crucial to ensure their integrity and reliability in high-stress environments.
