Hardox 450 Plates

Hardox 450 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. The hardness also increases the steel’s strength, with better dent resistance as a result. The high toughness also in cold conditions ensures that equipment can take impact forces without compromising its structural integrity.

What is  Hardox 450 Steel?

Hardox 450 steel is an abrasion resistant wear plate. Hardox steel is ideal for bodies that will be used for hauling very abrasive and high impact materials such as boulders, demo materials and medium to large aggregate.  450 Hardox has a yield strength of around 175,000 lbs minimum yield. That is 75% stronger than 100K steel, and 250% stronger than 50K steel. The strength of AR450 steel can improve weight savings over 50K much like 100K material because a thinner material can be used without sacrificing strength.

1) Brinell hardness, HBW, according to EN ISO 6506-1, on a milled surface 0.5 – 3 mm below surface. At least one test specimen per heat and 40 tons.

2) Hardness test is not performed or guaranteed for Hardox 450 cold rolled material. The hardness interval is a conversion from the tensile strength. The nominal thickness of supplied plates will not deviate more than +/- 15 mm from the thickness of the test specimen used for hardness testing.

Hardox is through-hardened. Minimum core hardness is 90% of the guaranteed minimum surface hardness.
