Welding electrode has now become an essential part of various manufacturing industries. AWS Class E316/316H-16 coated electrodes are widely used in welding applications due to their excellent physical and mechanical properties. It’s important to note that welding alloy is not just about applying heat to the base metal. The quality of the electrode used plays a crucial role in determining the durability and strength of the joint. This blog post will better understand AWS Class E316/316H-16 coated electrodes, including their composition, physical and mechanical properties, and various uses.
What are AWS Class E316/316H-16 Coated Electrodes?
AWS E316/316H-16 Coated Electrodes are welding electrodes for joining stainless steel and high nickel alloy components. They feature a flux core made of calcium silicate, which helps to reduce spatter and provides an excellent low-splatter arc performance. The deposited filler metal has excellent corrosion resistance, weldability, impact toughness and elevated temperature strength properties. It’s recommended for welding materials such as AISI 316 or 316L with either matching composition base materials or higher molybdenum content versions such as CN3MN or 25Cr-20Ni alloys. The electrode also exhibits superb crack resistance when used on metals with lower ferrite content, like 4xA grade austenitic stainless steels.
E316/316H-16 Welding Electrodes Composition
AWS Class E316/316H-16 coated electrodes are classified under the austenitic type of stainless steel electrodes. They have primarily been developed to offer durable and stable joints. These electrodes feature a low carbon content of around 0.04%-0.08% and predominantly consist of nickel, chromium and molybdenum, making them ideal for corrosion resistance and high-temperature applications.
