About Hastelloy C22 Electrodes
Hastelloy C22 Electrodes are welding electrodes manufactured using Alloy C22 (a nickel-chromium-molybdenum material with superior corrosion resistance). The chemical composition of Hastelloy C22 Electrodes is mainly based on its alloy composition, but additional elements like boron help enhance the desired properties of the finished product. Specifically, B16 (boron) is added in small quantities to adjust the electrode's hardness and grain size and create a beneficial microstructure better suited for withstanding extreme temperatures and corrosive environments. B16 also helps improve deposition rate and machinability. All these benefits combined make C22 Hastelloy Electrodes a reliable option for applications requiring high performance from their materials.
Exceptional Corrosion ResistanceBoasting a unique alloy composition, Hastelloy C22 Electrodes provide exceptional resistance against both oxidizing and reducing agents. This feature ensures long service life in aggressive environments such as chemical processing plants and offshore installations, reducing maintenance costs and enhancing overall system reliability.
Versatile Application and PerformanceSuitable for use with both AC and DC currents (operating range: 50-120A depending on diameter), these electrodes enable versatility in various welding setups. The rutile or basic coating type facilitates stable arc performance and smooth welds, making them ideal for demanding projects in several industrial sectors.
Clean and Safe PackagingEach electrode is presented in a bright, clean state, free from oil or contaminants. Hermetically sealed packs or cartons preserve their quality and extend shelf life, ensuring reliable performance right from the package.
