As the largest manufacturer of Super Duplex Fasteners, RatnaExports.com (India) is the largest manufacturer of these Fasteners. The Super Duplex 2507 Bolts are available in four grades, including martensitic, austenitic, ferritic, and precipitation-hardened stainless steel. It is important to note that Super Duplex Screws contain a more significant amount of chromium than other steels and, as a result, are incredibly corrosion-resistant. It is steel made up of super duplex steel. It combines improved resistance to pitting, high strength, stress corrosion, crevice corrosion, and cracking with a high level of corrosion resistance. Super Duplex 2507 Stud Bolts contain approximately 24% chromium.

In addition to being resistant to stress corrosion caused by sulfides and chlorides, the Super Duplex Steel Nuts are also made of the super duplex steel. It has a maximum carbon range of 0.03% for ASTM A479 and UNS S32750 Stud Bolts. Grade 2507 fasteners are often replaced with Duplex Steel 2205 Fasteners in many applications. Despite their high mechanical strength and properties, Super Duplex Stud Bolts offer various design advantages. We manufacture different kinds of super duplex washers in India based on the physical properties of these properties that offer design advantages. It is known that Super Duplex 2507 Bolts are also known as UNS S32750 Bolts in the engineering and aerospace departments. X2CrNiMoN25 Bolts are steel with 25% chromium (25Cr Duplex), 4% molybdenum, and 7% nickel.

RatnaExports.com is a leading Super Duplex Fastener Manufacturer and manufactures fasteners in the 2507 duplex grade. The composition of the Super Duplex 2507 Fasteners gives the Super Duplex 2507 Fasteners their strength and corrosion resistance. The metallurgical microstructure of Super Duplex 2507 Bolts and other fasteners has austenitic and ferritic steel phases. It enables them to endure high corrosion without compromising high strength. ASTM SA790 specifies bolts and rivets to be used with UNS S32750.

This specification covers fasteners for high-temperature and pressure applications. They range in size from M02 to M30 and are available in various lengths ranging from 2mm to 200mm. This super duplex material has different grades, such as S31803, S32507, etc., which are determined by their compositional differences. These UNS S32760 Fg Stud Bolts and other fasteners also have high strength.

In terms of tensile strength, the Super Duplex Bolts and Nuts have a minimum tensile strength of 795MPa and a minimum yield strength of 550MPa. These values are almost twice those of the austenitic stainless steel grades. We manufacture the Super Duplex Hex Bolt and other fasteners in various sizes, shapes, and specifications as a leading manufacturer and supplier of these fasteners. For more information on the different types, including the Super Duplex Stainless Steel Bolt, and their prices, please contact us.
