FCW V 312L
Stainless steel cored wire for 312 position welding
Product description
– Stainless steel flux-cored wire for gas-shielded arc welding
– Austeno-ferritic deposit of 29% chromium – 9% nickel type
– Specially designed for position welding
– Also suitable for flat welding
– Easy slag removal, excellent radiographic quality
– Very high vertical rise productivity
– Can be welded with mixed gas orCO2
Product application instructions
The high alloying level and high ferrite content of the deposited metal make Tetra V 312-G highly tolerant of hot cracking and dilution with a wide range of base metals.
Preheating can be minimized or even avoided. The deposited metal hardens and resists frictional wear.
Examples:
– Joining stainless steels of similar composition or ferritic stainless steels
– Heterogeneous assemblies between stainless steels and non- or low-alloy steels
– Underlayment before hardfacing
– Maintenance work on steels with limited weldability
– Welding of high-carbon hardening steels, of defined or undefined composition, and generally of all crack-sensitive steels such as tool steels, manganese steels, spring steels and high-speed steels.

Why choose this cored wire?
FCW V 312L is a rutile stainless steel flux-cored wire for welding dissimilar, difficult-to-weld or high-alloy steels. Thanks to its unique composition (29Cr-9Ni type), it offers excellent mechanical strength, ductility and crack resistance, even in extreme conditions.
The advantages of the FCW V 312L :
– Ideal for dissimilar or unfamiliar steels: perfect for joining or repairing manganese steels, tool steels, cast irons or austenitic and martensitic stainless steels.
-Very high resistance to cracking: the deposited metal absorbs mechanical stress without breaking.
– For maintenance and repair: often used for hardfacing, reconstituting or welding on worn or cracked parts.
-Excellent mechanical properties: high tensile strength and good toughness, even at low temperatures.
Very good bead appearance and easy-to-remove slag: clean finish, little clean-up.
-Versatility of use: works with several types of shielding gas (Ar+CO₂ or pure CO₂) and in different positions.
