|
AWS Class ERNiCrMo-3 MIG and TIG filler metal welding rods and wires are nickel-chromium-molybdenum alloys that are used to provide high-strength corrosion-resistant welds, particularly in chemical and petrochemical applications. Normal composition consists of about 62 percent Ni, 22 percent Cr, 9 percent Mo, 1.3 percent Mn, 0.5 percent Si and the lowest amount of carbon (0.03 percent). The tensile strength of about 8090 ksi (550620 Mpa), yield strength of 3050 ksi (205345 Mpa) and the elongation of 4050 percent and mechanical properties give excellent ductile, toughness and resistance to stress corrosion cracking. They can be used in combination with austenitic stainless steels as well as nickel alloys in strenuous situations.

At Hajji Welding Supplies, we take pride in being one of Tunis’s trusted suppliers of high-quality welding consumables. Our expertise lies in AWS Class ERNiCrMo-3 MIG and TIG Filler Metal, engineered for precision, durability, and resistance to corrosion. With a strong commitment to quality and customer satisfaction, we provide welding solutions that support industries across construction, energy, shipbuilding, and manufacturing.
AWS Class ERNiCrMo-3 MIG and TIG filler metal welding rods and wires are popular in welding high-performance nickel-chromium-molybdenum alloys especially in application where high level of corrosion and heat resistance is required. They are generally used in chemical and petrochemical processing facilities, marine and offshore facilities, power generation facilities, and pressure vessels with aggressive media. They work best with austenitic stainless steels, nickel-based alloys, and dissimilar metals and guarantee strong, durable, and crack free joints. These filler metals perform well in severe environments such as high temperatures and acidic or chloride-containing environments and are required in high reliability and long life critical parts of industrial applications.
The Hajji Industries Server is built to deliver reliability, speed, and scalability for mission-critical operations. Designed for modern industrial environments, it ensures seamless performance in manufacturing, engineering, energy, and automation sectors.
