Vinit Stainless‘s AWS E316/316H-16 electrodes are designed for high-temperature stainless steel welding in applications that require higher creep strength and heat resistance. These electrodes contain more carbon than 316L and are designed specifically for service temperatures above 500°C. They are suitable for application in thermal power plants, heat exchangers, boilers, and pressure vessels subjected to long term exposure at elevated temperatures. They provide reliable weld strength and resistance to corrosion under thermal cycling and stress. Due to their capability of structural integrity even at high temperatures, they are a choice in energy production, refineries, and high-pressure system fabrication.
E316/316H-16 electrodes have 18–20% Chromium, 11–14% Nickel, and 2–3% Molybdenum with 0.04–0.08% carbon content. Higher carbon content enhances high-temperature tensile and creep strength. Weld metal possesses tensile strength of approximately 620 MPa and is very suitable for elevated-temperature service. The electrodes show good weldability with good arc, low spatter, and easy slag removal. They are both AC and DC power source compatible and function well in flat, vertical, and overhead orientations. E316H is suitable for parts that experience thermal cycling and prolonged exposure to heat.
