Haste alloy is a nickel-based type of alloy. The alloy offers high resistance to corrosion and also from cracking and pitting. The alloy has been proved useful in such an application where if metal has been used can be oxidized. Some elements like chromium and molybdenum are also added in the alloy to make it strong. Hastelloy is also used in various chemical processes and also in gasoline refining. The alloy can also be used in welded condition because it does not form grain boundaries. They also offer good resistance from sulphuric acids and organic acids.
Fasteners made of Haste alloy also offer resistance from various solvent, formic and acetic acids. They also resist themselves from Hypochlorites and phosphoric acid. These fasteners can be in the form of nuts, bolts, or screws. They can be of various designs and diameters. They can also be custom made. They provide application in oil and gas services, in chemical processing, power industries and in flue gas desulphurization. Hastelloy B2 Fasteners are also used in pulp and paper industries and many such places where there are chances of other metals to get corroded.
To be reliable, they have to present with the EN test, Raw material certificate, Radiography report, and third party inspection report. They should have also passed the mechanical testing test, hardness test, flattening test, Micro and Major test, Flaring test, Hardness test. Positive metal identification or PMI testing is also an important test to prove the reliability of these fasteners. We make reliable quality 2.4617 Fasteners. Our products have also passed various lab tests to prove their ability. We also have enough stock of our products and can fulfill any quantity of demand at any time. We ensure the safe packaging and transportation of our products to make them safe during the delivery.
