Hardox® 450
Hardox® 450 is widely recognised as a highly versatile, abrasion-resistant steel with excellent structural properties. With an additional 50 HBW hardness over AR 400 grades, it offers greater wear resistance for a longer service life. This added hardness also enhances the steel’s strength, improving its resistance to dents. Its high toughness, even in cold conditions, ensures that equipment can withstand impact forces without compromising structural integrity.
Hardox® 450 Stockholder & Supplier
MTL Advanced Ltd is one of the largest Hardox® Weaparts Centre’s in the UK and is a Hardox® 450 stockholder/supplier to clients around the world, in industries such as automotive and recycling.
With various industry quality accreditations and many years’ experience working with this material, we are able to supply and manufacture Hardox® 450 in various sizes and thicknesses to satisfy the needs of our customers.
Due to our extensive in-house manufacturing capabilities, we can also machine, press parts up to 7.2m length and waterjet cut Hardox® 450 to the UK’s highest standards, avoiding a Heat Affected Zone (HAZ).

Fabrication and other recommendations
Hardox® steel can be machined and welded using conventional tools for high-strength steel. The grade of steel will guide this process.
Hardox® 450 and Hardox® 450 Tuf are not intended for further heat treatment. Mechanical properties are achieved 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 250 ºC.
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® 450?
Hardox® 450 is the most popular abrasion-resistant steel with excellent structural properties and a nominal hardness of 450 HBW. It provides good bendability and weldability and can be used in many components and structures that are subject to wear.
As a result of its long wear life and MTL’s manufacturing expertise, this steel offers high quality and a low cost.
