Duplex Stud Bolt Italy
First made at Avesta, Sweden in 1930s, Duplex grade stud bolts are a common sight today. Duplex grades are a mixed microstructure of almost equal parts Austenite and Ferrite, creating a combination of both their properties; hence the name DUPLEX. Duplex stainless steels provide high corrosion resistance coupled with high strength, making it a desirable material.
Along with higher strength (higher than Austenite and Ferrite), good weldability and toughness they also offer resistance to stress corrosion cracking. Given all these features duplex material makes the ideal contender as the material for use of stud bolts.
Why choose Faco Fasteners?
At Faco Fasteners, along with duplex, we offer a wide array of fasteners to match the requirements of oil, gas and petrochemical industries. Stud bolts come in ranges of from nominal dia ¼” to 4” and can be tailor made in terms of length, if required. Duplex stud bolts are available in full threads and partial threads. Along with Duplex, we also provide stud bolts made from Carbon steel, Mild steel or Alloy Steel, Ferritic & Austenitic Stainless Steel. The stud bolts follow different standard and specifications like the ASTM / ASME / BS / DIN / BS EN ISO and are shaped with different threads as follows UNC, 8UN, UNF, Metric Coarse & Fine Series. The surface finishes we offer include Self Color, Hot Dip Galvanized, Electro Galvanized, Di-Chromated, P.T.F.E. Coated, as well as, any other as per order requirement.
