Super Duplex Fasteners
Viha Steel & Forging is a leading Super Duplex Fasteners Manufacturer and we produce the fasteners in the 2507 duplex grade. The Super Duplex 2507 Fasteners get their strength and corrosion resistance from the material composition. There are austenitic and ferritic steel phases in the metallurgic microstructure of the Super Duplex 2507 Bolts and other fasteners. So they can withstand high corrosion without compromising the high strength as well. The specification for the UNS S32750 Bolts and fasteners is the ASTM SA790. The specification covers fasteners for high temperature and pressure applications. The sizes range from M02 to M30. The length of the UNS S32760 Stud Bolts range from 2mm to 200mm. There are different grades within this super duplex material such as S31803, S32507 and so on depending on the compositional difference. The UNS S32760 Fg Stud Bolts and other fasteners also have high strength values.
The minimum tensile strength of the fasteners is 795MPa and the minimum yield strength of the Super Duplex Bolts And Nuts is 550MPa. These are almost double the values of the austenitic stainless steel grades. As a leading manufacturer and supplier of these fasteners, we produce the Super Duplex Hex Bolt and other fasteners in different specifications, sizes and shapes. Please feel free to contact us for more information on the different types such as the Super Duplex Stainless Steel Bolt and their pricing.
