AR450 Steel is a type of abrasion resistant steel that has a
surface hardness of 420-470 Hardness Brinell. It is a high-carbon
steel alloy composed of several different elements, such as carbon
and boron. Its unique composition and treatment allow it to provide
more surface hardness than AR400, while maintaining good ductility,
formability, and impact resistance.
Sizes Offered
As one of the leading abrasion resistant providers in the industry,
Ford Steel houses an assortment of AR450 steel plates in different
thicknesses. The common range of thickness for AR450 steel plates
range from ⅛ inch to 4 inches and come in a variety of lengths
depending on the application requirement.
- Thickness: 1/8” thru 4”
- Widths: 48” thru 96”
- Lengths: 96” thru 288”
Heat-Treatment
The steels are not intended to be heat treated during or after
fabrication. Tempering at moderate temperatures, 150°C – 200°C, is
the only heat treatment which will without fail allow the steel to
retain its original wearing properties.
Flame Cutting
A heat affected zone will build up on a thermally cut surface which
is similar to the heat affected zone on a fusion welded steel
surface. The surface hardens to a depth of 1mm-2mm during flame
cutting and post heat results in a soft tempered layer below this.
When flame cutting, the pre-heating and working temperature
instructions concerning welding can be used as a guideline. In
practice it is advisable to preheat when cutting plates, if the
thickness is over 10mm.
The maximum allowable working temperature must be kept below 200°C
in order that the wear resistance will meet requirements throughout
the plate. The cooling of a cut surface must not be accelerated
under any circumstances, on the contrary, the cooling of the plate
surface can be slowed down if necessary. A plate brought in from
cold outside storage must be allowed to warm up sufficiently before
cutting.
Abrasion resistant 450 plate protects your equipment from
corrosion, wear, and impact. The steel is superior for applications
that require more durability, minimizing the lost production time
because of worn-out parts. AR450 has many other benefits including:
- Less Cost
- Less weight without sacrificing strength
- Extremely durable
- High Impact resistance
The greatest differentiator between AR450, AR400, and AR500 is the
hardness that each achieves. Typically, AR400 is between 360-440
Brinell, while AR450 is around 429-495 Brinell, and AR500 between 460-544 Brinell.
Another key differentiator is applications. While all three types
of abrasion resistance steel offer great hardness, they vary in
terms of formability and brittleness.
In applications where the steel must be hard with good formability,
AR400 and AR450 are typically used. When wear is a critical issue
that a certain application faces, AR500 may be more appropriate due
to its increased hardness and wear resistance over the other two
carbon alloys.
Cost is another factor that can impact the choice of
abrasion-resistant steel. AR450 and AR500 are both more costly than
AR400, as they achieve higher degrees of hardness. In some
instances, you may choose to use a less costly option that may need
to be replaced more frequently rather than the more expensive
option.
Common Industries and Applications
Our AR450 steel plates meet all requirements and standards for EN
10029 and EN 10051. Available Services: Drilling and machining,
welding, shearing and unching, forming, Fabrication.
AR450 steel plates are used in heavy equipment manufacturing jobs
that rely on it to protect the equipment from extensive wear. The
steel plates should not be used in load-bearing or structural
design to support extensive amounts of weight. Common industries
that use AR450 steel are mining, power, aggregation, cement,
pulp/paper, sand & gravel, asphalt, scrap, and slag.
