Product description

This wire EN ISO 14171-A: S2 is a solid wire for Submerged Arc Welding (SAW), mainly used for welding unalloyed or low-alloy steels. It is designated as “S2” wire, which corresponds to a standard chemical composition for general steel applications.

Product application instructions

Non-alloy structural steels acc. to EN 10025 and ASTM: S235JRG2 / A570 Gr. 36 to S355J2G3R / A572 Gr. 50
suitable fluxes BF 1, BF 3 and BF 4

Fine grain steels acc. to EN 10025, EN 10028 and ASTM: up to P355N / S355NL / A516 Gr. 70
suitable fluxes BF 1, BF 3, BF 4, BF 5.1, BF 6.5 and BF 10

Pipe steels acc. to ISO 3183, EN 10208 and API-5: L415N / X60
suitable fluxes BF 5.1, BF 6.30 and BF 6.5

Boiler steels acc. to EN 10028 and ASTM: P235GH / A516 Gr.55, P355GH / A516 Gr. 70 and S275J2G3 / A572
Gr. 42, S355J2G3 / A572 Gr. 50
suitable fluxes BF 1, BF 3, BF 4, BF 5.1 and BF 6.5

Flux type suitability is strongly dependent on its application. In combination with the wire electrode the most suitable flux should match the requirements of the plate material as closely as possible under the existing welding conditions. Further information can be obtained from the technical flux data sheets.

Mechanical characteristics

Why choose ABRAFIL AS 40?

1. Perfect for unalloyed steels (S235, S355, etc.)

ABRAFIL AS 40 is designed for welding general-purpose mild steels, such as :

    • metal frames

    • heavy boilermaking

    • tubes, tanks, wagons, industrial chassis

2. Excellent productivity in submerged welding

Combined with a suitable flux, ABRAFIL AS 40 allows :

    • very high welding speed

    • a very high deposit rate

    • Smooth, spatter-free welds

3. Very good mechanical strength with basic or neutral flux

  • ABRAFIL AS 40 has a tensile strength of around 500-560 MPa, depending on the flux used.

  • Good resilience down to -20°C or more, depending on the combination (some fluxes even allow -40°C).

4. Good tolerance to slightly oxidized steels

  • Thanks to its manganese and silicon content, S2 wire effectively deoxidizes the melt.

  • This makes it possible to weld without having to strip the metal, which is a real industrial asset.
