First, commonly used general steel wire

1. DY-YJ502 (Q) titanium core type slag cored wire. Excellent process and mechanical properties, capable of all-position welding, especially excellent low temperature toughness, to achieve the classification of the class 3y certification. Widely used in shipbuilding, steel structures, bridges, etc.

2. DY-YJ507 (Q) alkali-type slag cored steel wire. Excellent mechanical properties, low diffusible hydrogen content, and excellent low temperature crack resistance. The -40 degree impact energy can reach 80 or more. Used in machinery manufacturing, hydropower, petrochemical equipment, etc.

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

4. YJ502CrNiCu (Q) titanium all-position welding cored steel wire. Used for welding of atmospheric corrosion resistant steel. Such as welding of offshore platforms.

5. YJ502Ni (Q) titanium all-position welding cored steel wire. Low-temperature impact absorption is high, meeting the use of metal structures at -40 掳C.
