XL-HARD DISC-NM

XL-HARD DISC-NM is a special shaped composite abrasion–resistant disc metallurgically formulated to give a uniform 60 Rc deposit. It has more than 50% carbides and 3-4 times wear resistance of AR plate.

Salient Features :

• Lowest dilusion
• Uniform hardness throughout deposit.

Advantages :

Compared with  weld overlay

• Can be applied to a given area in approx. one tenth of the time of manual arc welding and approx. one quarter of the time of semi-automatic welding.
• Gives a constant 60 HRC hardness through hard layer whereas weld deposits show a hardness reduction due to base metal dilution.
• Does not effect the base metal by excessive heat input. High heat input, which is often the case with welding procedures, can result in a reduction of the mechanical properties of the base metal.

Compared with wear plates

• Is of easily manageable size and weight, easily transported and stored.
• Being of one size and shape, there is no need to carry different sizes and shapes of wear plates.
• Can be applied in approx. half the time it takes to apply a wear plate, saving both on down time and labour costs.

Applications :

Applications are found in Chutes, Buldozer Blades, Mixing paddles, Shovels, Scraper blades, Screw conveyors etc.
