Strength of unalloyed and low alloyed consumables

Unalloyed and low-alloyed consumables with a maximum yield strength of 500 MPa (72 ksi) are generally recommended for Hardox® steel. Low-alloyed consumables result in lower hardness of the weld metal, potentially reducing wear rate. If wear properties are essential, the top cap of the joint could be welded with consumables used for hardfacing, such as Duroxite®.

Consumables of higher strength (up to 900 MPa/130 ksi) may be used for Hardox® 400 and 450 in the thickness range of 0.7-6.0 mm (0.028”-0.236”).

The recommended consumables for Hardox® steel and their designations according to the American Welding Society (AWS) and the European Committee for Standardization (EN) classifications can be found in the table below.

More about information and choosing welding consumables can be found in Welding Consumables.
