What is Inconel 600 /601 /625 Fasteners ?
Sumit Impex are Inconel 600/601/625 Fasteners manufacturer distributor & export. Inconel 600/601 Fasteners Suspensioners (UNS N06600) have been designed to serve cryogenic and high temperature service temperatures within the range of 2000 degree F. Inconel 600 Fasteners Suspensioners (UNS N06601) are characterized by their resistance to high oxidation temperature and continues to be extremely resistant to oxidation below 2200 deg F. The commodity is made according to international standards and requirements, with the highest quality raw material. In Inconel Alloy Fasteners such as 600, 601 are available in different grades.
Inconel fasteners are highly formable in all the common methods and can be easily welded. Alloy 600 Fasteners, also known as high alloy, are applied to improve their resistance to heavy acid cuts, such as sulphuric acid. This Inconel 600/601 fasteners are used for mining, manufacture of chemicals, manufacture of aluminum and steel, agriculture, gasoline refineries, transport and utilities, machinery, etc.

Inconel fixtures, like Inconel 600 & 601, consist of a nickel-chromium-molybdenum alloy band, which are used to maintain a high strength at high temperatures and a strong resistance to corrosion. With the high alloy level of Inconel 600/601 fixtures, a wide variety of harsh corrosive conditions can be avoided.
Our Inconel 600/601, which does not harden with heat treatment, can be treated by rinsing. Such Inconel 600/601 bolts are used in pipes, fittings, and other parts that are subjected to 1100 degree F–1800 Degree F corrosion attack. The excellent resistance against chloride stress-corrosion cracking is another important characteristic of our Inconel Alloy Washing.
