Thickness: 3-80mm
Width: 1250mm, 1500mm, 1800mm, 2000mm, 2200mm
Length: 6000mm, 8000mm, 10000mm, or cut to required.
- Description
Wear resistant steel are produced from processes of hot rolling, cutting into length and heat treating. The products are characterized with small thickness, good flatness, outstanding wear resistance, excellent toughness, good weldability, good machinablility, consistent property and quality.
Wear resistant steels are developed for applications where high wear resistant performance is required, such as dumper, garbage vehicle, concrete mixer truck, industrial air fan, hopper, crusher, machinery for coal, grain, cement, grab bucket, etc.

| SERVICE | DESCRIPTION |
| Cutting | 1. Can be cut by plasma, laser, water jet, arc gouge, and abrasive saw cutting; 2. Cannot be cut by oxy-fuel. |
| Welding | 1. Use 480 MPa (70 ksi) or 560 MPa (80 ksi) consumable to join base metal; 2. After welding, joint should be capped by overlay for wear protection. |
| Machining | 1. Not machinable by conventional methods; 2. Can be finished by grinding only; 3. Countersunk holes can be precisely produced by EDM (Electrical Discharge Machining). |
| Forming | 1. Commonly formed with overlay to the inside; 2. For pipes with diameters smaller than 0.6m (24″), hardfacing pipe recommended instead of pipes fabricated from hardfacing plate. |
| Drilling | 1. When drilling, the distance between two holes should be at least 15mm (5/8”); otherwise, the partition may not be strong enough and can crack; 2. The minimum diameter of holes should be equal to the thickness of the plates. For thicker plates with a total thickness over 20mm (3/4”), the minimum diameter should be 1.5 times the thickness of the plate. |
