Super Duplex Fasteners Manufacturer in India
Manufacturer of UNS S32760 Stud Bolts in India, Provides Custom Sizes
There are standard duplex, lean duplex and Super Duplex fasteners based on the chemical composition. The Super Duplex Screw is a Super Duplex made fastener. In size, the fasteners are 3mm to 200mm while the lengths are M02 to M30. Their types include the ASTM A479 UNS S32750 Threaded Rod which acts to join two parts with or without a nut.
The specification is the ASTM A479 for this grade of fasteners with standards ranging as ASTM, BS, IS and other international standards. The 2507 Super Duplex Nuts and Bolts have resistance to crevice and pitting corrosion, oxidation and atmospheric corrosion. Therefore the application of the Super Duplex Studs can be seen in the general, petroleum, petrochemical, sea water, marine and in other industrial applications.
Regal Sales Corporation is a leading manufacturer and supplier of the different Super Duplex 2507 Bolts and other fasteners. Please feel free to contact us for more information on the different types such as the Super Duplex washers and other fasteners.
