Harshita Stainless, a prominent manufacturer and supplier located in Delhi, India, specializes in high-quality AWS Class E330-16 Electrodes, crafted specifically for welding high-temperature austenitic stainless steels. These electrodes are perfect for applications that face extreme heat, oxidation, and thermal cycling, like furnace components and heat treatment equipment. E330-16 electrodes boast impressive resistance to scaling and oxidation at temperatures up to 1150°C (2100°F), ensuring stable arc performance, minimal spatter, and robust, crack-resistant welds. Harshita Stainless is committed to delivering consistent quality and metallurgical properties, making these electrodes a trusted choice for industries such as metallurgy, petrochemicals, refineries, and thermal processing.
When it comes to composition and mechanical properties, AWS Class E330-16 Electrodes typically consist of about 34–37% Nickel, 14–17% Chromium, along with low amounts of carbon, silicon, and manganese, all engineered to maintain strength and oxidation resistance at high temperatures. The weld metal exhibits excellent thermal fatigue resistance and keeps its mechanical integrity even under cyclic heating conditions. Typical mechanical properties include a tensile strength of around 550 MPa, yield strength of about 320 MPa, and an elongation of 30%. These electrodes are compatible with both AC and DC+ polarity, providing a smooth, stable arc and producing high-quality welds in flat, horizontal, and vertical positions.
