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.

Dec 22, 2024 · Hardox and AR steel both offer high levels of hardness and toughness, but there are notable differences between them. Hardox steel is known for its consistent through-hardening, which ensures uniform hardness throughout the material, making it highly durable and suitable for demanding applications.

Hardox® 450: 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. Hardness test is not performed or guaranteed for Hardox 450 cold rolled material.

Hardox® 450 is an abrasion-resistant wear steel plate with a nominal hardness of 450 HBW. The 450 combines good bendability and weldability with an option for guaranteed impact toughness (Hardox® 450 Tuf).

Aug 28, 2023 · Hardox 450 is ideal for high-wear applications like mining, construction, and earthmoving industries. AR450 is suitable for moderate-wear applications, such as transportation equipment, farm machinery, and manufacturing equipment.

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.

A premium and trademarked brand of formable abrasion resistant plates produced by SSAB with a nominal Brinell hardness of 450. Hardox® 450 steel is intended for applications where demands are imposed on abrasion resistance with good cold bending applications.

For high horsepower grinders being used as a secondary grinder, I would use either AR400 / Hardox 400 or AR450 / Hardox 450. This will wear noticeably longer than the T1 assuming there are no contaminants in the material. For smaller HP grinders, I recommend AR400 / Hardox 400 or AR450 / Hardox 450.

Hardox® 450 is a versatile, wear- and abrasion-resistant steel at 450 HBW that combines good bendability and weldability with an option for guaranteed impact toughness (Hardox 450 Tuf). It can be used in many different components and structures that are subject to wear.

Hardox® 450, with an extra 50 Brinell hardness over our 400 grade, provides beter dent and abrasion resistance as well as longer wear life, so you can achieve even greater savings.
