OSTEEL also provides abrasion resistant steel plates and grinding balls.

Abrasion resistant plates are widely applied for machinary working in harsh envirements where good abrasion resistant and high strength performance are required.

OSTEEL adopts low alloy chemistry design and clean steel providing this kind of steel plates with high hardness, high strength, good toughness and weldability.

Applied Fields

The series of abrasion resistant steel plates are mainly applied for the machinery which are used in the industry of mining, construction, cement, port, power station and metallurgy,

such as scraper, bulldozer, excavator, loader, dump truck,cement mechanics,PCI devives, chute, crusher, grinder, mixer, filter, barge and etc..

The application of abrasion resistant steel plates prolongs the life expectancy and performance of the machinery, thus reduces the production cost.

Remark:

1.R-bending radius,a-plate thckness;

2.Regarding mechanical properties shown in the table, apart from hardness, other technical indexes are negotiable.

3.During hardness testing, the surface of the sample should be milled by 1mm to 2.5mm, then the surface hardness will be tested.
