TOKO AWS A5.4 E312-16, stainless steel welding rods that are often used for general-purpose welding of mild and low-alloy steels. The rods are low-hydrogen electrodes that produce welds of high quality with good bead characteristics and a smooth arc transfer. They produce high impact toughness, mechanically sound welds with good bead shape, porosity, and slag detachability. They are often used in all welding positions and can provide excellent results on low-alloy and mild steels under a variety of welding conditions..

Can be used by anyone, regardless of prior welding experience. Features a superior combination of tensile strength and elongation. The arc is so ionized that you can not short it out.

E312-16 is used for welding type 316L or 318 stainless steels. It has a maximum of .04% carbon content in the weld metal, which reduces the possibility of carbine precipitation and consequent intergranular corrosion. This electrode is widely used in the welding of chemical equipment..

Features of E312-16

  • Can be used for joining hard to weld materials and dissimilar metals
  • Applications should be limited to 800°F (420°C)
  • The weld deposits exhibit high tensile strength and offer some resistance to abrasion
  • Weld deposits work-hardens and allows for good wear resistance

Typical Applications

  • Tool Steels
  • Hard to Weld Steels
  • Cast and Wrought Alloys
  • Dissimilar Metals
