Harsh Metalloys, a top-notch manufacturer and supplier based in Mumbai, India, proudly presents its premium-quality AWS Class E308/308H-16 Electrodes, specifically crafted for welding austenitic stainless steels. These electrodes are engineered to deliver outstanding performance when working with 304H and other high-carbon stainless steel grades. The E308/308H-16 electrodes excel in strength and corrosion resistance, even at high temperatures, making them perfect for demanding service applications. With a stable arc, minimal spatter, and a smooth bead finish, these electrodes are well-suited for both structural and pressure-containing welds across various industries, including petrochemical, power generation, chemical processing, and marine engineering.
When it comes to composition and mechanical properties, the AWS Class E308/308H-16 Electrodes feature a weld deposit that contains around 19–21% Chromium and 9–11% Nickel, along with a higher carbon content (up to 0.08%) compared to standard 308 electrodes, enhancing their high-temperature creep strength. The weld metal typically boasts a tensile strength exceeding 580 MPa and remarkable ductility. These electrodes are designed for all-position welding (except vertical down) and can be used with either AC or DC+ current. The rutile-based flux coating ensures easy slag removal and an attractive bead appearance. Their mechanical integrity and heat resistance make them an excellent choice for welding thick sections of high-carbon austenitic stainless steel.

E308/308H-16 light coated electrodes deliver a smooth arc performance, making them perfect for welding stainless steel that requires moderate heat resistance and corrosion protection in lighter applications.
E308/308H-16 heavy coated electrodes excel in providing deep penetration, easy slag removal, and top-notch weld quality, making them ideal for heavy-duty stainless steel fabrication in structural, pressure vessel, and chemical settings.
E308/308H-16 shielded arc electrodes are crafted for manual arc welding of 304/304H stainless steels, ensuring strong welds that resist intergranular corrosion and heat.
AWS Class E308/308H-16 Electrodes are primarily used for welding high-carbon stainless steels such as 304H, 347H, and other austenitic grades that require improved high-temperature strength. These electrodes are widely employed in boiler fabrication, heat exchangers, pressure vessels, superheater tubes, and other thermal equipment in the petrochemical and power generation industries. Their high creep resistance and mechanical strength make them suitable for environments exposed to cyclic thermal stress. E308/308H-16 electrodes are also utilized in refinery piping, chemical processing units, and structural components where elevated temperature performance and metallurgical stability are critical.
