Stainless Steel 309S Stud Bolts

The chemical composition of 309s stainless steel stud bolts is as follows: Cr: 22-24%, Ni: 12-15%, Mn: 2.00%, Si: 0.75%, P: 0.045%, and S: 0.03%. This combination of elements offers excellent resistance to corrosion, good formability and weldability, and good mechanical properties at elevated temperatures.

309s stainless steel stud bolts are used primarily in industrial and residential settings due to their high corrosion resistance, good formability and weldability, and good mechanical properties at elevated temperatures. They are used for various applications, including construction, piping systems, power plants, heat exchangers, boilers, and more. This steel grade offers excellent fatigue strength, tensile strength, high yield strength, and a moderate level of ductility.
