Material and Grade: Stainless Steel A4-70 Stud Bolts are typically manufactured from AISI 316 stainless steel, which is also known as A4 stainless steel. This grade contains 18% chromium, 10% nickel, and 2-3% molybdenum, providing excellent corrosion resistance, especially in marine and corrosive environments. The "A4-70" designation indicates the material grade and its mechanical properties. The "A4" signifies AISI 316 stainless steel, and the "70" represents the minimum tensile strength, approximately 700 MPa, making these stud bolts suitable for demanding applications.


Design and Function: Stud bolts have threads on both ends, allowing them to be screwed into a threaded hole or fastened with nuts on both ends. They are often used to create a threaded connection between two components, such as flanges, pipes, or machinery parts. The threaded design provides a secure and reliable connection.


Applications: Stainless Steel A4-70 Stud Bolts are commonly used in various industries and applications, particularly in environments where corrosion resistance is crucial. These may include marine applications, chemical processing plants, offshore drilling rigs, and anywhere exposure to saltwater, chemicals, or harsh atmospheric conditions is a concern. Stud bolts provide a durable and corrosion-resistant fastening solution in such settings.


Corrosion Resistance: AISI 316 stainless steel (A4) is known for its outstanding corrosion resistance properties. It is highly resistant to rust, staining, and corrosion when exposed to moisture, saltwater, and various chemicals. This makes A4-70 Stud Bolts suitable for use in aggressive and corrosive environments.

Machining and Fabrication: Stainless Steel A4-70 Stud Bolts can be somewhat more challenging to machine compared to lower-grade stainless steels due to their increased hardness. Carbide tooling is often recommended for drilling and cutting. Proper cutting speeds, feeds, and lubrication should be used to prevent overheating and work hardening of the material.
