Hardox® 450 is probably the world’s most recognized wear-resistant steel, with tight tolerances
and excellent structural properties, only from SSAB. With a nominal hardness of 450 HBW,
Hardox® 450 combines good bendability and excellent weldability. The extra 50 HBW hardness
over our Hardox® 400 grade provides better dent and abrasion resistance as well as longer wear
life. Or you can use the additional hardness to reduce plate thickness and get lighter equipment.
Hardox® 450 has been setting the benchmark for quality steel for more than 30 years, for good
reason. It has a solid reputation as a highly versatile, abrasion-resistant steel that also has
structural properties. With an extra 50 HBW hardness over AR 400 grades, it provides additional
wear resistance for an extended service life with similar toughness as an AR 400 steel. This allows
for more high-performing buckets, dump bodies and other equipment that lasts longer and still
can take impact forces without compromising structural integrity.
Hardox® 450 consistently outperforms mild steel, whether it’s S235, S355, A36, grade 50, A514,
SS400, S45C or any AR 400 grade. That’s why it’s the industry standard for hard-wearing, hard-
working equipment. Mild steel simply doesn’t have the strength to enable modern excavators or
other machines to perform at their full potential. Premature maintenance or repairs just because
the business end of your equipment isn’t hard or strong enough is neither convenient nor cost-
effective. When switching to Hardox® 450 from such steels, expect a more productive operation
with less downtime.
Dimension Range
Hardox® 450 is available in thicknesses of 3.2 - 160 mm as plate, as sheet in thicknesses 2.0 -
8.0 mm and as CR sheet in thicknesses 0.8 - 2.1 mm.
Hardox® 450, made from SSAB Zero™ steel, is now available in thicknesses ranging from 4.0 to
25.4 mm. For plate thicknesses over 80 mm, the preferred width is 1650 mm. More detailed
information on dimensions is provided in the dimension program.
