Routile flux cored wire suitable for welding stainless steels with an alloy content between 16 to 21% Cr and 8 to 13% Ni, stabilised or not. Service temperatures are typically -196°C to about 400°C.

Meltolit 309L

Routile flux cored wire for welding stainless steels of similar composition or ferritic stainless steels.
Joining stainless steels to mild and low-alloyed steels. Rebuilding and buffering before cladding or hardfacing. Maintenance on « hard-to-weld steels ». Examples: Dissimilar welds between stainless steels type 304, 304L, 316, 316L, 318, 316Ti, 321, 410 or ferritic stainless steels type 1.4713, 1.4724, 1.4742, 3Cr12, to non or low alloyed CMn steels, for service temperatures up to 400°C.

Meltolit 309L-PW

Routile flux cored wire for welding stainless steels of similar composition or ferritic stainless steels.
Joining stainless steels to mild and low-alloyed steels. Rebuilding and buffering before cladding or hardfacing. Maintenance on « hard-to-weld steels ». Examples: Dissimilar welds between stainless steels type 304, 304L, 316, 316L, 318, 316Ti, 321, 410 or ferritic stainless steels type 1.4713, 1.4724, 1.4742, 3Cr12, to non or low alloyed CMn steels, for service temperatures up to 400°C. Especially produced for position welding.

Meltolit 309L Mo

Routile flux cored wire for welding stainless steels of similar composition or ferritic stainless steels. Joining stainless steels to mild and low-alloyed steels. Rebuilding and buffering before cladding or hardfacing. Maintenance on « hard-to-weld steels ». Examples:Dissimilar welds between stainless CrNiMo stainless steels and mild or low alloyed CMn steels, for service temperatures up to 350°C. Tetra S 309LMo-G has superior resistance to dilution when compared to 309L deposits because of its higher alloy and ferrite content. Compared to the AWS 312 weldments it benefits from an improved strength/ ductility balance.

Meltolit 309L Mo-PW

Routile flux cored wire for welding stainless steels of similar composition or ferritic stainless steels. Joining stainless steels to mild and low-alloyed steels. Rebuilding and buffering before cladding or hardfacing. Maintenance on « hard-to-weld steels ». Examples:Dissimilar welds between stainless CrNiMo stainless steels and mild or low alloyed CMn steels, for service temperatures up to 350°C. Tetra S 309LMo-G has superior resistance to dilution when compared to 309L deposits because of its higher alloy and ferrite content. Compared to the AWS 312 weldments it benefits from an improved strength/ ductility balance. Especially produced for position welding.

Meltolit 310

Routile flux cored wire resistant to oxidation and scaling up to 1100°C. It is suitable for welding cast or wrought stainless steels of similar composition and heat resistant ferritic stainless steels.

Meltolit 253

Routile flux cored wire where the weld metal has a scaling temperature beyond 1000°C. The controlled carbon and ferrite levels improve microstructural stability and high temperature strength compared to the 309(L) types whereas the lower nickel content provides better resistance against sulphur attack than the 310 grade. For welding ex 309(S30900), AVESTA 153MA(S30415) and AVESTA 253MA(S30815).

Meltolit 312

Routile flux cored wire with high alloy content and high ferrite ratio which allow it to benefit from extreme tolerance to hot cracking and to dilution with a wide range of base materials. Preheat can often be avoided or minimised.
The weld deposit workhardens and gives good wear and friction resistance. Examples: Welding stainless steels of similar composition or ferritic stainless steels. Joining stainless steels to mild and low-alloyed steels. Buffer layers before hardsurfacing. Maintenance on « hard-to-weld steels ». Welding high carbon hardenable steels, of known or unknown composition and generally most of steels subject to cracking such as tool steels, manganese steels, spring steels and high-speed steels.

Meltolit 316L
