Jun 10, 2017

First, commonly used general wire

1, DY-YJ502 (Q) titanium slag-based flux cored wire. Technology, excellent mechanical properties, to all-position welding, in particular, excellent low-temperature toughness, in order to achieve the classification society 3y-level certification. Widely used in shipbuilding, steel, bridges and so on.

2, DY-YJ507 (Q) alkali slag flux cored wire. Excellent mechanical properties, low diffusion hydrogen content, with excellent low temperature cracking resistance. -40 degrees impact energy can reach more than 80. For machinery manufacturing, hydropower, petrochemical equipment.

3, DY-YJ607 (Q) alkali slag of the flux-cored wire. Excellent mechanical properties, low diffusion hydrogen content, suitable for 60 kg high strength and high toughness steel welding.

4, YJ502CrNiCu (Q) titanium all-position welding flux cored wire. For the corrosion of atmospheric corrosion of steel. Such as the offshore platform for welding.

5, YJ502Ni (Q) Titanium all-position welding flux cored wire. Low temperature impact absorption is high, to meet the use of metal structure at -40 degrees temperature.

Second, heat-resistant steel series of flux-cored wire

1, DY-YR302 (Q) titanium slag of the flux-cored wire, for 1Cr-0.5Mo and 1.25Cr-0.5Mo heat-resistant steel welding, widely used in boiler and pressure vessel industry.

2, DY-YR312 (Q) for 12CrMoV pearlitic heat-resistant steel welding, widely used in boiler and pressure vessel industry.

3, DY-YR317 (Q) alkaline slag flux cored wire. Applicable to 12CrMoV pearlite heat-resistant steel welding, with excellent low-temperature impact performance.

4, DY-YR402 (Q) for 2.25Cr-1Mo heat-resistant steel welding.

Third, stainless steel gas protection welding flux wire

1, DY-YA308 (Q) 18% Cr-8% Ni stainless steel welding.

2, DY-YA308L (Q) ultra-low carbon 18% Cr-8% Ni stainless steel welding.

3, DY-YA309 (Q) dissimilar steel welding or composite steel and surfacing stainless steel when the transition layer welding.

4, DY-YA316 (Q) 18% Cr-12% Ni stainless steel welding. [1] 

Four, gas protection welding flux cored wire

1, DY-YD350 (Q) Widely used in surfacing intermetallic wear parts and mild soil sand wear parts, HRC35.

2, DY-YD450 (Q) suitable for surfacing resistance to sand wear and resistance to inter-metal wear parts, HRC45.

3, DY-YD600 (Q) Widely used for abrasive wear parts, HRC55-60.

5, buried arc welding flux cored wire

1, DY-YD14 (M) is mainly used for the repair of carbon steel and low alloy steel parts or for other surfacing materials, HRC26 ± 2.

2, DY-YD224B (M) is mainly used for hot rolling and other wear parts of the welding and repair, HRC59.

3, DY-YD420 (M) chromium 13% of the martensitic welding flux cored wire, corrosion resistance, wear resistance. Applicable to continuous casting roll, steam valve, wedge valve, safety valve and other parts of the hard surface surfacing.

4, DY-YD423 (M) for high temperature hot roll and continuous casting roll hard surface surfacing, the surfacing layer has excellent corrosion resistance, wear resistance and thermal shock resistance, HRC45-48.

5, DY-YD430 (M) chromium 17% ferrite-type surfacing flux-cored wire for corrosion-resistant hard surface surfacing, with good high temperature corrosion resistance, and stainless steel composite steel backing welding, HRC23.

6, DY-YD414N (M) nitrogen-containing martensite-type welding flux-cored wire to nitrogen and carbon to improve its hardness and crack resistance, with good corrosion resistance, wear resistance and thermal shock resistance. For hardfacing of continuous casting rolls, HRC43.
