|
AWS Class E309/309H-16 Coated Electrodes are composed of high chromium (23–25%) and nickel (12–14%) with low carbon content in the 309H variant, enhancing resistance to intergranular corrosion and maintaining stability at elevated temperatures. These electrodes deliver excellent mechanical properties, including tensile strength of around 550 MPa, yield strength of 350 MPa, and elongation of 35%. The weld metal offers superior oxidation resistance up to 1000°C, making it suitable for joining dissimilar metals, stainless steel to carbon steel, and applications requiring high thermal strength and durability.
