FCW 310 Gas Shielded Flux Cored Welding Wire
Filler Metal FCW 310 is a flux cored wire used for join¬ing heat resistant austenitic steels of type AISI 310 and for surfacing low or non-alloyed steels where a 310-type deposit is desired. Fully austenitic deposit, this flux cored wire welds 25Cr-20Ni type 310 wrought and cast stainless steels with up to 2% carbon.Employed for applications involving the attack of oxidizing, nitrogen-containing or low-oxygen gases.
The high scaling tempera¬ture and excellent oxidation resistance of the FCW 310 make it ideal for welding in chemical processing and nuclear plants as well as for furnace and heat treatment equipment, steam boiler construction, the crude oil industry and the ceramics industry.
This cored wire can be used in air up to about 1100°C, in oxidizing sulphurous atmospheres up to 1100°C and in reducing sulphurous atmospheres up to 650°C.
Scaling resistance up to +1200 °C. Cryogenic toughness down to - 196 °C.
The temperature range between +650 and +900 °C should be avoided owing to the risk of embrittlement.
FCW 310 was developed for flat or horizontal welding position (AWS E310T0-4).
This cored wire was formu¬lated for use with 75% Argon/25% CO2 shielding gas.
The slag is self-peeling and mini¬mizes cleanup.
The 75/25 mix¬ture will produce a smooth arc with virtually no spatter and slightly higher yield and tensile strengths than CO2.
The mechanical properties and deposit analysis will meet AWS 5.22 specifications.
Available in diam.: 1.2 mm; on spools of 12.5 kgs:
