GENERAL CHARACTERISTICS

Flux cored wire for joining corrosion-proof Cr-Ni- steels with low carbon content as well as stabilised and non-stabilised steels of identical or similar characteristics which are resistant to chemical agents. Used on a base metal of identical characteristics the weld metal is resistant to wet corrosion up to 350° C and is scale resistant up to 800°C in an air and oxidising gases atmosphere. No intercrystalline corrosion due to low carbon content. The deposits are capable of taking high polish.

GENERAL CHARACTERISTICS

Flux cored wire with an alloyed core, suitable for joining difficult-to-weld steels and for corrosion-proof claddings. An austenitic weld metal (Cr Ni Mo 18/ 10/ 2) is obtained already in the first layer. The alloy is also suitable for welding buffer layers on plated metal sheets and for joining austenitic to ferritic steels which are subject to service temperatures of up to 350° C. Due to its high alloy level CORODUR TS 309 L Mo produces crack-proof welds. The addition of molybdenum ensures higher corrosion resistance and higher tensile-strength at elevated temperatures, as compared to the moly-free material 1.4829. The weld metal is heat resistant and non-scaling up to 1050° C.

APPLICATION

Dissimilar joints of:
1.4583 with H I / H II. 17 Mn 4. StE 355.
1.4583 with P235GH / P256GH, P295GH, P355N
Buffering before cladding
Joining of stainless steels to mild or low-alloyed steels at high dilution levels

GENERAL CHARACTERISTICS

Flux cored wire for joining difficult-to-weld steels and for corrosion - proof plating. An austenitic 18/10 type Cr-Ni- weld metal can be obtained already in the first layer. The alloy is also suitable for buffer layers on plated metal sheets. The highly alloyed weld metal deposited by the wire ensures crack - proof welds and is scale-resistant up to 1000°C. The deposits are capable of taking high polish.

GENERAL CHARACTERISTICS

Rutile flux cored stainless steel wire for gas shielded arc welding with 29% chromium and 9% nickel. Attractive bead appearance, easy slag release, very good penetration, high productivity and excellent X-ray soundness. The maximum performances in the horizontal and downhand position are welded with classical economical Ar-CO2 mixtures or CO₂.

APPLICATION

Its high alloy content and high ferrite ratio allow CORODUR TS 312 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 of alloys to be welded

Welding stainless steels of similar composition or ferritic stainless steels and joining of stainless steels to mild and low-alloyed steels. Buffer layers before hardsurfacing and maintenance on “hard-to-weld steels”. Welding of 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
