Stainless Steel ER502 Filler Wire is a ferritic stainless steel alloy with excellent welding properties, primarily utilized for joining stainless steels of the same grade. Its chemical composition includes C Max 0.06%, Si Max 1.00%, Mn Max 2.00%, P Max 0.040%, S Max 0.030%, Cr 10.5 to 12.5%, Mo Null, Ni 4-6%. Its high chromium content gives it superior corrosion resistance properties, while its other elements provide strength and weldability to the filler wire. It has good formability and ductility and is helpful in temperatures ranging from cryogenic to up to 2000°F (1093°C). In Summary, this filler wire provides various advantages in numerous applications ranging from furniture manufacturing to petrochemical industry apparatus fabrication, making it an indispensable all-rounder in the field of stainless steel welding materials.

The uses and properties of ss filler wire make it an ideal choice for various welding applications. Its low carbon content makes it less likely to cause carbide precipitation, while its high chromium and nickel levels give it excellent corrosion resistance. This makes it ideal for welding in environments with a risk of exposure to corrosive elements. In addition, the high levels of molybdenum give the wire good pitting resistance, making it ideal for welding in high-temperature applications.
