Abrasion Plate Manufacturing and Welding

Wear resistance is basically defined by hardness. Our abrasion plate is quenched and tempered to a high degree of hardness thus in a great number of constructions its use will lead to substantial increase in service life. Depending on the type of wear, parameters such as chemical composition and micro structure take effect. A characteristic of our plate is the addition of chromium which has produced the best results. The chemical composition is designed to provide thorough hardening of the thickness involved.

Abrasion Plate Typical Applications

Excavating, mining, earthmoving, conveying, crushing, scrap process machinery and any
application which requires a high resistance to wear.

Abrasion Plate Fabrication Details

Our abrasion plate is designed to have excellent working characteristics both under workshop conditions and on site.

Abrasion Plate Cutting

Our abrasion plate can be flame cut without problems. Plasma and laser cutting produce particularly good results. Due to the high temperatures and rapid cooling involved the cut edge will be as hard or harder than the original material. For thicknesses up to 30mm preheat is not normally necessary, however if the ambient temperature is below +5°C or the cut edge is to be cold formed, preheating to 120 – 150°C should be considered. (For preheat temperatures see welding recommendations).

Abrasion Plate Welding

Our abrasion plate can be perfectly welded along the lines of any proven process. The requirements listed below should be met to obtain welds with no cracks and full bearing strength:

  • Use of suitable alloyed filler metals to obtain such mechanical properties in the welded material as will meet the requirements.
  • Humidity should be excluded during welding to ensure low hydrogen contents in the weld metal in order to prevent cold cracking. Therefore, filler metals and zones to be welded should be thoroughly dried.
  • Choice of adequate thermal cycles during welding to obtain controlled cooling rates in the weld metal and the heat affected zone in order to reach the required mechanical properties. Controlled cooling rates are feasible through limited heat input.
