What is a hardfacing alloy?
Tungsten carbide, Wear resistant alloys, Hardfacing, Ferrous metals and alloys, Nonferrous metals and alloys. HARDFACING can be broadly defined as the application of a wear-resistant material, in depth, to the vulnerable (or worn) surfaces of a component by a weld overlay or thermal spray process.
What is hardfacing metal?
Hardfacing, also known as hardsurfacing, is the application of buildup or wear-resistant weld metals to a part’s surface by means of welding or joining.
What is nickel based electrode?
An all position basic coated electrode depositing a nickel chromium based alloy with additions of molybdenum, tungsten and niobium. The electrode is especially designed for welding of 9% nickel steels for cryogenic applications down to -196°C.
What Colmonoy 5?
Abstract. COLMONOY NO. 5 comprises a chromium-boride-containing, nickel-base alloy recommended for hard surfacing parts to resist wear, corrosion, heat and galling. Deposits, which have only moderate hardness (Rockwell C 45-50), may be machined with carbide tooling.
Can you weld on hardfacing?
Hardfacing is a metalworking process where harder or tougher material is applied to a base metal. It is welded to the base material, and generally takes the form of specialized electrodes for arc welding or filler rod for oxyacetylene and gas tungsten arc welding welding.
What is hardfacing used for?
Hardfacing is the application of hard, wear-resistant material to the surface of a component by welding, thermal spraying, or a similar process, mainly to reduce wear. Hardfacing is used on original equipment as well as for the repair of worn components.
What is Inconel made out of?
nickel
Composition. Inconel alloys vary widely in their compositions, but all are predominantly nickel, with chromium as the second element.
What is Colmonoy coating?
Colmonoy 88 is an alloy coating material developed by Wall Colmonoy and protected under US Patent 5,141,571. This alloy was developed to provide extended service life at elevated temperatures to parts exposed to abrasion, erosion, corrosion, fretting and galling. Forms Available. Bare rod (Gas and GTAW)
Can you use 7018 for hardfacing?
Choosing a hardface overlay Deposits may spall and come loose. The softer alloy should always be applied beneath the harder deposit. Never use 7018 as a cushion or build-up. It does not have the hardness and strength for hardfacing applications.
What welding rod is used for hardfacing?
Stoody X-53 is a hardfacing electrode that combines the desired features of high deposition rate, high bead build up, and resistance to impact and abrasion. It can be used to overlay carbon or manganese steel parts. Stoody XHC combines excellent weldability with a high deposition rate.
Can you machine hardfacing?
Yes! In fact, those are two (2) of the primary uses of hardfacing. Since the process is used to deposit material to the surface, you can use it to enhance the durability and the strength of your part or component.
