Solid Wire Rod BA-TIG 310 for TIG Welding

Classification:
EN ISO 14343-A: W 25 20
SFA 5.9 / AWS A5.9: ER310

Main Application

BA-TIG 310 is a solid wire rod for GTAW, 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.
