The Preferred Nickel, Chromium and Iron Alloy used when Corrosion and Heat Resistance is Required

Posted By : Aubrey Mead , on Mar, 2016


The use of Inconel 600 Bar is the material preferred by manufactures when they have a component that will be exposed to corrosive material and high temperatures. This material is a nickel-chromium-iron alloy made to withstand the rigors of industrial applications.

 Chemical Components of this Alloy

This alloy composes of a minimum of 72% nickel with 14.0 to 17.0% chromium and 6.0 to 10.0% iron. There are also manganese, sulfur, silicon carbon and cooper at amounts less than 1% each.

Characteristics of Inconel 600

This alloy has a density of 0.306 lb/in3 and melting point of 2,575 F. It is also resistant to oxidation up to temperatures of 2,000 F. It is also very restraint to both acidic and caustic corrosion and it is also non-magnetic.

Welding of this Alloy

This alloy and be joined by conventional welding techniques used in industry that include metal-arc, tungsten gas-arc and gas-metal-acr.

Hot Working

Hot working temperature for this alloy is between 1,600 and 2,250 F. In the range of 1,200 to 1,600 F hot work should not occur due to the ductility of the alloy decreases in that range of temperature.

Cold Machining of this Alloy

A high speed drill bit is required which will have to be lubricated with a sulfur-based oil to reduce the friction and heat. If welding is to occur after this machining, the oil must be removed in its entirety or the surface area could lose of its preferred characteristics.

Applications for this Alloy

The use of this material is preferred over both steel and aluminum in high temperature application because of its characteristic to resist creeping caused by crystal vacancies when exposed to high temperatures. Industries that use this alloy include aerospace, gas turbine and nuclear fusion.

Inconel 600 Bar is the right material for applications that will be exposed to not only high temperatures, but above average stress levels that the material will experience. It is also known for its high surface stability in extreme conditions where it can maintain its shape and strength.
