Increasing Life of Skip Car Deflectors using Overlay Wear Plates by NanoSteel Co.

The NanoSteel Company is an advanced materials company which has created a unique and proprietary portfolio of nanotechnology based and environmentally friendly steel alloys that greatly increase the value of steel in most of today’s industrial applications.

Product success has been through the development of Super Hard Steel® (SHS) alloys which feature nanoscale microstructures. SHS alloys are for use as metallic coatings within power generation, mining, cement, concrete and oil & gas industries.

Applied by thermal spray and weld overlay processes, NanoSteel SHS alloys dramatically increase the service life of industrial components subject to wear and corrosion environments, eliminating the need for costly alternatives and environmentally dangerous chrome plating.

Industrial Wear Problem

Skip cars are used in underground mining for transporting ore in process from one station to the next. During loading and unloading, wear plate inside the cars are exposed to sliding abrasion and impact.

NanoSteel Overlay Wear Plate Increasing Life of Skip Car Deflector

To increase the life of the skip car deflector and reduce surface material loss, the mine installed NanoSteel® overlay wear plate, 1/2 inch thickness (3/16 inch overlay on 5/16 inch substrate), for resisting sliding abrasion and impact.

NanoSteel overlay wear plate after deflecting 410,000 tons and exceeding Q&T plate life by 1.2x

NanoSteel overlay wear plate has exceeded Q&T plate life by 1.8x

Nanosteel overlay wear plate has exceeded Q&T plate life by 2.9x

NanoSteel Exceeds Life of Q&T Plate by 2.9x and CrC Plate by 2x

The NanoSteel overlay wear plate was removed from service for maintenance after deflecting more than 1 million tons of ore. This represents a service life increase of 2.9x over 500 Brinell quench & temper (Q&T) monolithic wear plate, 5/8 inch thickness, and up to 2x over chrome carbide (CrC) overlay wear plate, 5/8 inch thickness (5/16 inch overlay on 5/16 inch substrate). Upon being placed back in service, mine engineers predicted that the NanoSteel plate will exceed Q&T plate life by 4.3x before requiring replacement.
