Descrição de Produto

Nm400 Nm450 Nm500 Wear/Abrasion Resisant Steel Plate for Loading Machinery

NM series is a high-strength wear resistant steel plate with high hardness. The Brinell hardness value from 470 to 525 (HBW), and mainly to provide protection in the occasion or part where wear resistance is required, so that the equipment life is longer and the maintenance is reduced.

 

Typical Applications: 
HART-P-100 Plate is widely used in the mining, power generation(Coal), cement, dredging, steel production, waste handling, glass production, and pulp and paper industries. Some specific applications include:

INDUSTRY	APPLICATONS
Mining	Chutes, hoppers, liners for truck beds, dozer blades, shovel buckets, dragline buckets, excavators
Cement	Separator guide vanes, discharge cones for clinker storage bins, chutes for sintering ore conveying, outlet ducts for clinker grinding mills, receiving hoppers
Dredging	Dredging pipes and pumps, suction pipelines, pump discharges
Steel	Dredging pipes and pumps, suction pipelines, pump discharges
Power	Coal handling chutes, coal feeder liners, crusher screen plates, classifier cones, journal liners, silo bunkers

Service:

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.

Testing and quality control:
We documented how the product properties are tested in order to make sure the overlay plates fulfil the specified product properties. Including documentation on 3d party's quality system if calibration and testing is performed by 3d party.
