Fabrication and other recommendations
Welding, bending and machining Recommendations can be found in SSAB’s brochures at www.hardox.com or consult Tech Support, help@ssab.com.
Hardox® 550 is not intended for further heat treatment. It has obtained its mechanical properties by quenching and when necessary by means of subsequent tempering. The properties of the delivery condition cannot be retained after exposure to temperatures in excess of 250ºC.
Appropriate health and safety precautions must be taken when welding, cutting, grinding or otherwise working on this product. Grinding, especially of primer coated plates, may produce dust with a high particle concentration.
What is Hardox® 550?
Hardox® 550 is a Q&T martensitic wearplate for applications that demand high resistance to abrasion, such as hammers, shredders and cutters for the recycling industry.
The wear plate significantly extends service life, but not at the expense of crack integrity, and cuts maintenance costs.
