Inconel 625 Fasteners

UNS N06625 Fasteners, DIN 2.4856 Fasteners

We are Manufacture, Suplier & Export of Inconel 625 Fasteners that are actually manufactured from High Quality of Standard Raw Materials and are designed as per with national and international standards. Alloy 625 fasteners have exceptional resistance to crevice corrosion and stress corrosion cracking, as well as chemical attack under highly oxidizing to moderately reducing conditions. UNS N06625 Fasteners is frequently used in chemical processing, oil & gas, naval and aerospace industries. From cryogenic temperatures, Inconel 625 Fasteners (UNS N06625) can be functioned up to 645 Degree F (340 Degree C).

Inconel 625 screws have high strength and resistance to cryogenic temperatures up to 1093 degrees C (2000 degrees F). Inconel Alloy 625 Fasteners ability to hold out extraordinary stress and a comprehensive range of heats, both in & out of water, besides being able to repel corrosion while exposing to very much acidic environments forms it a suitable choice for marine and nuclear applications.
