Hardox 550 Pipes from Luke Steel represent cutting-edge abrasion-resistant piping made for very severe wear environments. With a nominal hardness of 550 HBW, these pipes are perfect for applications where regular hard steels wear out too soon. Luke Steel’s domestic manufacturing and engineering support enable clients to confidently use advanced wear solutions, especially in high-demand industrial sectors.
Hardox 550 Pipes are alloyed with carbon, manganese, chromium, and boron, achieving ultra-high hardness (550 HBW) and robust mechanical properties. They include a yield strength of 1450 MPa, a tensile strength of up to 1600 MPa, and 6–8% elongation. Toughness is maintained through careful microstructure management, and weldability is possible with proper preheating and post-weld heat treatment, depending on wall thickness and joint complexity.
