AWS A5.9: ER310

AWS A5.9: ER310

AWS A5.9: ER310 is a solid wire electrode for GMAW, suitable for joining heat resistant fully austenitic steels type 25Cr/20Ni. Service temperature up to 1100°C in air and up to 1050°C in oxidizing sulphurous atmospheres, reducing sulphurous atmospheres up to 650°C. Service temperature between +650 and +900 °C should be avoided due to the risk of embrittlement.AWS A5.9: ER309LSi is a solid wire electrode for GMAW with higher Si content than AWS A5.9: ER 309L, suitable for joining stainless Cr-Ni steels type 309, Cr-steels and dissimilar steels like austenitic stainless steels to mild or low-alloyed steels, buffer layers and overlays on C-Mn, mild steel or low alloy steels and for joining 304L/321. Also recommended for welding 12% Cr ferritic steels.
