Alloy 625 bolts, UNS N06625 nuts, threaded rods, stud bolts, socket head cap screws etc. are used in marine, offshore, aerospace, power generation, oil & gas, chemical processing and so on where high strength and toughness are demanded.
Why Choose Inconel 625 Fasteners?
The Inconel 625 Fasteners are a highly reliable fastening solution for various industrial applications. They are made from a nickel-based superalloy of chromium, molybdenum, and niobium, which gives them excellent mechanical strength without the need of precipitation hardening.
As a manufacturer and supplier, we offer best quality Nickel Alloy 625 Fasteners that are manufactured and supplied strictly to national and international standards as well as according to customer's specification. Our Inconel 625 Fasteners are available in types like Alloy 625 Bolts, UNS N06625 Nuts, washers, stud bolts, threaded rods, hex bolts, heavy hex nuts and custom fastening solutions for severe environments.
The excellent tensile strength, superior fatigue life and outstanding resistance to corrosion attack in presence of chlorides, high-temperature and sea water makes the Inconel 625 Fasteners a widely adopted choice for these applications.
What are Inconel 625 Fasteners?
Industrial fasteners made with the use of Nickel Alloy 625, or UNS N06625 and W. Nr. 2.4856. It gets its properties from the use of the metal alloy which is a Ni-Cr based superalloy with solid-solution strength given by the use of the metals molybdenum and niobium.
These fasteners don't collapse and bend where a normal stainless steel fastener would. They are also commonly used when corrosion from various types of stress corrosion cracking, pitting and crevice corrosion and oxidation occur where conventional stainless steels cannot endure the conditions.
