Majority of nickel-based steel alloys are highly resistant to corrosion, Hastelloy being the best of them. It is a superalloy prepared primarily from nickel and small percentage of many other elements. Designed to endure great stress and high temperature, the corrosion-resistance of Hastelloy is supreme when it comes to performance. Other than the great resistance that the Hastelloy offers to all manners of cracking or pitting, parts made from this metal blend have a tendency to have optimal performance for several chemical applications, which might oxidize the metals. Other elements like chromium or molybdenum add to the profile of this alloy, which proves to be one of the toughest around.
What is Hastelloy and What Forms Does it Come in?
Hastelloy comes in different forms ranging from open dies to shafts, plates, sheets and contour rings. Regardless of the shape of Hastelloy, it offers the benefits like high-temperature force in the environment and vacuum, which are chemically static. Hastelloy metal has grown as the most preferred option for offering more resistance to corrosion than any other metal like the one Ni-Cr-Mo. Parts made from Hastelloy are being used for demanding applications while its sizing is decisive. Electropolishing is used frequently as sizing operation for the simple reason that it removes surface material in consistent amount even from the complex parts. This facilitates sizing of parts without any requisite of warping the shape and altering the proportion.
How do you make Hastelloy?
The making of Hastelloy is a complex process that involves the mixing of many elements like tungsten, carbon, titanium, aluminum, manganese, copper, cobalt, chromium etc into the basic ingredient of the transition metal that is essentially a nickel based substance. Hastelloy parts have the basic properties of having the ability to withstand not only high temperatures but also a high stress environment in a moderate or maybe even a highly corrosive environment. This property gives Hastelloy the edge over the other metal counterparts that would fail when used in applications like nuclear reactors, gas turbine engines etc.
