For ordinary electrode with less stress, Z308 electrode and Z408 electrode can be used.For critical and critical equipment with high stress, it is recommended to use U.S. -made MG289 cast iron electrode for welding.MG289 welding rod (there are many fake products in the market, it is recommended to buy from regular companies).The specific performance is as follows:

MG289

N is a high strength alloy used for welding dirty cast iron.

Welding deposits can be processed.

N is designed for welding dirty and greasy cast iron.

N for low pressure water welding of cast iron pipes.

N alloy metal welding core design, coated with a unique flux, with anti-crack function.

N welds easily anywhere.

N purposes, such as:

- welded cast iron and steel - welded - drive gearbox for different cast iron

- gray cast iron, malleable cast iron or ductile iron - lower duct

Technical parameters (typical)

Tensile strength up to 60,000 pounds per square inch (415 newtons per square millimeter)

Hardness HB210
