Product Catalog


Alloy Type:

Alloy 3000T is the ultimate electrode for welding steels with highest strength and maximum ductility.  Assures non-cracking welds on “problem” steels such as high carbon steels; tool steels; stainless steels; spring steels; manganese steels; and dissimilar steels. Alloy 3000T is particularly advantageous when the alloy content of the steel to be welded is unknown.  This is  the perfect choice for any maintenance or repair of ferrous metals.
