If you are in the field of engineering or metallurgy, you might have come across AWS Class ENiCrMo-10. This is a high-performance welding alloy used for various purposes in different industries. ENiCrMo-10 combines various elements that provide unique properties, making it different from other welding alloys. This blog post will discuss several aspects of AWS Class ENiCrMo-10, including its composition, physical and mechanical properties, and heat treatment. We will also discuss the applications of this alloy and conclude with its corrosion resistance ability.
What is AWS Class ENiCrMo-10?
AWS Class ENiCrMo-10 (AWS A5.14) electrodes are nickel-chromium-molybdenum (NiCrMo) electrodes with 10% chromium and 6.9% molybdenum addition. The electrodes have excellent weldability, provide good deposition rates, and can be used to join high alloy steels such as stainless steel or low alloy nickel base alloys with similar composition. They are ideal for welding dissimilar metals such as carbon steels, precipitation-hardening stainless steels, and some austenitic chrome molybdenum alloys. These multi-purpose coated electrode products offer superior resistance to corrosion, good machinability properties and ductility in most welding positions like flat & horizontal while also being capable of operating at very high temperatures without cracking or becoming brittle over time.
ENiCrMo-10 Welding Wire Composition
ENiCrMo-10 is an alloy of 60-70% nickel, 22-25% chromium, 9-11% molybdenum, and 0.5-1.0% tungsten. The alloy also contains small percentages of carbon, silicon, and manganese. The elements present in this welding alloy provide it with excellent corrosion resistance, strength, and durability.
