What is AWS Class ERNiCr-3 MIG and TIG Filler Metal?

AWS Class ERNiCr-3 MIG and TIG fillers are nickel-chromium-iron alloys that are aimed at strength, toughness, and corrosion. They are normally made of Nickel 6772% Chromium 1822% Iron 610% and trace levels of Manganese, Copper and Silicon to raise weldability. Mechanical properties They have tensile strength of about 550-650 megawatts, yield strength of about 240-300 megawatts and ductility of 30-35 percent which provides high levels of ductility and durability. ERNiCr-3 is recommended to work with Inconel 600, 601, 690 and others and is very suitable in welding of oxidizing and corrosive service conditions with high temperatures.

AWS Class ERNiCr-3 MIG and TIG Filler Metal Uses

The AWS Class ERNiCr-3 MIG and TIG filler metals are common in welding nickel-chromium-iron alloys (Inconel 600 601 690) and in joining dissimilar metals (stainless steels and nickel alloys). They are very good in terms of their strength and corrosive properties and thus are suitable in high temperature and oxidizing conditions. Typical uses are the making of heat exchangers, boilers, pressure vessels, piping systems and furnace parts in petrochemical and power generation, aerospace and marine industries. ERNiCr-3 provides long-lasting, ductile, and corrosion-free welds hence ideal in the cases involving critical operations in the harsh environments of industries.
