Harsh Metalloys stands out as a top manufacturer and supplier of AWS Class E312-16 Electrodes, proudly based in Mumbai, India. These stainless steel electrodes are expertly crafted for welding dissimilar metals, especially in situations where high tensile strength and crack resistance are crucial. Known for their outstanding performance on challenging steels, E312-16 electrodes provide stable arc characteristics, a smooth bead finish, and minimal spatter. Adhering to strict quality standards, Harsh Metalloys ensures reliable electrodes that are perfect for heavy-duty applications in industries like construction, mining, shipbuilding, power generation, and chemical processing, where durability and metallurgical compatibility are key.
AWS Class E312-16 Electrodes boast a high alloy content, typically featuring 29–32% chromium and 8–10% nickel. The weld metal develops a duplex structure (austenite and ferrite), which delivers remarkable tensile strength and crack resistance. Typical mechanical properties include a tensile strength of at least 830 MPa, yield strength of at least 600 MPa, and an elongation of around 25%. These electrodes are compatible with both AC and DC+ polarity and excel in all standard welding positions. Their distinctive composition makes them incredibly versatile for joining dissimilar metals and for applications that experience high stress or dynamic loading.

Designed for high corrosion resistance, these electrodes feature a light coating for better arc stability and smooth weld appearance. They come in sizes such as 1/8 inch and 3/32 inch, ideal for welding dissimilar metals.
Known for enhanced corrosion resistance, these electrodes have a heavier coating that improves arc stability and slag removal. Available in sizes like 3/16 inch and 5/32 inch, they are suitable for high-strength applications and vertical positions.
These electrodes are designed for shielded arc welding, offering excellent corrosion resistance and superior weld strength and durability. Typically available in 1/8 inch and 5/32 inch sizes, they are used for welding stainless steel to carbon steel.
AWS Class E312-16 Electrodes are perfect for welding different types of steels, such as manganese, high-carbon, tool, and stainless steels, to carbon or low-alloy steels. Thanks to their impressive strength and resistance to cracking, they’re great for repairing castings, welding hardened steels, connecting tricky or hard-to-weld metals, and creating buffer layers before hard-facing. Industries like mining, shipbuilding, power generation, cement production, and heavy equipment manufacturing really benefit from the reliable performance of E312-16. These electrodes are also commonly used in structural repairs, pressure vessels, and pump components, particularly in situations that involve thermal cycling, mechanical stress, and harsh or abrasive environments.
