Abrazo 400 Plates

ABRAZO 400 Plates or Abrasion resistant steel plate is also known in the engineering industry by a variety of other names which include:
• Wear resistant plate
• Wear plate
• 400 Brinell plate


This range of steel plate products has been developed specifically for long service life in abrasive conditions. These products are suitable for a variety of applications in areas such as mining and quarrying, process industries, material handling and construction, and earthmoving. As designers and plant operators strive to extend service life of critical components and reduce the effect of unscheduled maintenance downtime, the benefits of employing wear resistant material in applications involving impact and/or sliding contact with abrasive material are immense.

Steel plate for use in abrasive conditions is unusual in that it is more widely specified by a brand name than by a particular national or international steel specification. Many steel plate manufacturers produce their own brand of abrasion resistant steel and these are usually distinguished by a brand name followed by the hardness of the steel which is measured in Brinell units. The harder a steel the more difficult it is to fabricate and weld. For this reason steel with hardness of around 400 Brinell is the most commonly specified and used. However hot rolled steel plate products for more exacting abrasive conditions are readily available in 500 Brinell hardness while even harder steel plates are also manufactured.

Abrasion Resistant Steel Plate

Champak Industries supply abrasion resistant steel in the form of gas or plasma cut profiles to exacting tolerances or as formed, drilled, or machined parts. It is of course also available as plate straight from our stocks.

Utilised in applications such as tipper bodies, cutting edges, crushing machinery, and excavator buckets, abrasion resistant plate is available in 400, 450, and 500 Brinell hardness.

We stock Abrazo plates manufactured by Tata Steel as well as proprietary brands from other steel plate manufacturers.

Fabrication of Abrasion Resistant Steel Plate

Abrasion resistant steel plate can be easily welded and fabricated but its high hardness and strength compared with mild steel means that it should be treated with some caution.
