Alloy 2507 Hex Bolts and UNS S32760/ S32750 Socket Head Cap Screws manufacturer in India

Super Duplex 2507 Fasteners play a critical role in the construction of all sorts of everyday objects. It encompasses a fairly broad category of tools, such as screws, nuts and bolts, that share a common purpose i.e. to mechanically hold objects together.  It is austenitic-ferritic iron chromium – nickel alloy with molybdenum addition.  It has very good tensile strength and high resistance to stress corrosion cracking at moderate temperatures, compared to that of conventional austenitic stainless steels. Super Duplex Fasteners mechanically hold objects together. It is form of non-permanent joint. If you use a fastener to connect two components, you can remove it, and the separate pieces and it will come apart without suffering any damage. The same case wouldn’t be for the welded joint. It has excellent resistance to chloride stress corrosion cracking, low coefficient of thermal expansion, high thermal conductivity. The high chromium, nickel, and molybdenum level offers excellent resistance to pitting, crevice, and general corrosion. Super Duplex 2507 Bolts contains 25% chromium, 4% molybdenum, and 7% nickel which is manufactured for demanding applications which needs exceptional strength and corrosion resistance, such as petrochemical, chemical process, and seawater equipment. The strength of Super Duplex Bolts has been found to be approximately 100% stronger than regular stainless steel grades and has better ductility than ferritic stainless steel grades. Super Duplex Screws is a broad category of mechanical fastener with a threaded shaft, designed to screw into a part. It has an excellent corrosion resistance with combined high strength which makes them ideal for marine environments and offshore applications.
