Super Duplex UNS S32760 /F55 Fasteners have good strength and high corrosion resistance properties due to the ferritic and austenitic stainless steel phases in the metallurgic microstructure. The material is made up of 24% chromium, 3% molybdenum, 6% nickel, carbon, manganese, silicon, phosphorus, sulfur, nitrogen and iron in the composition. There are different types of fasteners such as the ASTM A1082 UNS S32760 Bolts, nuts, washers and threaded rods in this grade of material.

The different types of fasteners have different dimensions. The material has 1350 degrees Celsius melting point. The UNS S32760 Hex Bolts are stronger with 800MPa minimum tensile strength and 550MPa minimum yield strength. The hex design of the bolts also provide the bolts with high torque capacities. The material has 15% elongation rate and high hardness as well. The ASTM A1082 U Bolts can come in sizes ranging from M12 to M56 or from ½ inches to 2 ¼ inches. The diameter of the different fasteners ranges from M10 to M100 or from 3/8 inches to 4 inches. There are different types of bolts such as the UNS S32760 F55 Eye Bolt. The eye bolts are used for heavy load bearing applications. There are also different types of surface finishes to the fasteners such as hot dip galvanized and electrogalvanized finishes. There are other competitive fasteners such as the UNS S32760 Zeron 100 Heavy Hex Bolt and nuts. The application of these fasteners can be seen in marine, ship building, chemical, food processing, heat exchanger, power plant applications and in super heater elements.
Zeron 100 UNS S32760 Fasteners are made up of the S32760 alloy. It has 25% chromium, 3.6% molybdenum and 0.7% tungsten in the composition. The material is therefore resistant to various organic acids and chlorides. The Super Duplex Zeron 100 Stud, hex bolts, screws, self-tapping screws, nuts and washers come in different dimensions and standards for different application types. There are nickel, silicon, carbon, manganese, nitrogen, sulfur, phosphorus, copper and iron present in various quantities as well. The UNS S32760 Bolts can have different strength values after solution annealing treatment. The minimum tensile strength is 800MPa and the minimum yield strength is 550MPa with 25% elongation rate. The Zeron 100 Fastener dimensions vary according to the standards and types. The specification is ASTM F60, F51 or F55 for the fasteners of this grade. The standards vary as DIN, ASTM and other international standards with sizes ranging from M02 to M30 or 3/6 inches to 2 inches. The length of the Super Duplex UNS S32760 Stud Bolts and other fasteners can range from 3mm to 200mm. The different types such as flange bolts, heavy hex bolts, lag bolts, T bolts, Zeron 100 Screws, sel-tapping screw, set screw and others have better corrosion resistance and strength.
