UNS S32760/F55 Fasteners have excellent strength features together with high corrosion resistance mainly because of the ferritic-austenitic Stainless Steel phases in metallurgical microstructure. The material with the composition that includes 24% of chromium, 3% of molybdenum, 6% of nickel, carbon, manganese and silicon, phosphorus, sulfur, nitrogen, iron. Some of the fasteners include the ASTM A1082 UNS S32760 Bolts, nuts, washers and threaded rods are available in material grade.
As you can see from the table, the dimensions of the different types of fasteners vary. The material has 1350 degrees Celsius capacity for melting. UNS S32760 Hex Bolts are stronger with 800MPa minimum tensile strength and 550MPa the minimum yield strengths. It also gives the bolts hex design and high torque capacities to the bolts. This material has elongation rate of 15% and high hardness as well. The ASTM A1082 U Bolts can be manufactured in metric dimensions from M12 up to M 56 or in inches between ½ to 2 ¼ inches. It measures from M10 to M100, or 3/8 to 4 inches, and is of five different types: [/ISSN: 0258-9498] Some of the bolts include 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.
UNS S32760 Zeron 100 fasteners are categorically produced using the S32760 grade of alloy material. The content is a quarter of chromium, 3.6 per cent molybdenum and 0.7 per cent tungsten. The material is thus, able to resist, various organic acids and chlorides. The Super Duplex Zeron 100 Stud includes the hex bolts, screws, self-tapping screws, nuts and washers also are produced in several size and type to be used for several functions.
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.
Table of Content
ASTM A182 F55 bolts are premium bolts designed from a duplex stainless steel material composition. This material uses many of the properties of the ferritic stainless steel, with added corrosion resistance properties of austenitic stainless steel. F55 bolts are capable of sustaining pressure and heat conditions and are applied mostly in oil and gas and petrochemicals sector.
