Product Description
ER308 and ER308L stainless steel welding wires are two commonly used stainless steel welding materials.
Mechanical properties
ER308: The tensile strength of the welded joint is generally not less than 520MPa, and the elongation is not less than 35%. It has good strength and plasticity, and can meet the mechanical performance requirements of most stainless steel structures.
ER308L: The mechanical properties are similar to those of ER308, but due to the lower carbon content, the toughness of its weld metal may be slightly higher, which is more advantageous in some occasions where toughness requirements are high. The tensile strength of the welded joint can usually reach more than 520MPa, and the elongation is not less than 35%.
Welding characteristics
ER308: The arc is stable, the droplet transition is uniform, the spatter is small, and the weld is beautiful. It has good welding processability and is suitable for a variety of welding methods, such as manual arc welding, gas shielded welding, submerged arc welding, etc. It can better guarantee the quality and performance of the weld, and has a certain adaptability to fluctuations in welding parameters.
ER308L: In addition to the welding characteristics of ER308, due to its low carbon content, less carbides are produced during the welding process, thereby reducing the risk of intergranular corrosion caused by carbide precipitation. Therefore, ER308L has better welding effects when welding some stainless steel materials with high requirements for intergranular corrosion resistance. At the same time, it also has good crack resistance and can adapt to more complex welding structures and working conditions.
