XL-XAR 500

The manufacturer of the world famous X’tralife Wear Plates now present the evolutionary XL-XAR-500 wear plate developed specifically to cater the ardous needs of the core sector industry in the millennium.

XL-XAR-500 is used at the discretion  of  the  purchaser for wear -exposed structures, e.g excavating , mining and earth-moving machinery, truck dump bodies, conveying, crushing  and pulverizing equipment , scrap presses and paving moulds.

This is a through hard tempered plate with good wearresistance & toughness.

Physical Properties :

• Hardness : 50-54 Rc.
• Yield Strength : 1250-1300 Mpa.
• Tensile Strength : 1500 -1550 Mpa
• Elongation(%) : 9.5%

NOTE: Plate is heat  treatable, hence hardness can change on heating.

The products made of this steel are suitable for cold bending provided, that consideration is given to the high hardness. The formability of steel decreases with increasing hardness this has to be kept in mind when forming. The forming must take place at a slow and steady rate, the cut edges must be deburred and the plates heated, if necessary, prior to the forming. A final stress- relieving is not necessary for this steel.

Inspite of its high wearresistance, the steel exhibits good machinability if sufficiently heavy machine-tools and sharp carbide-tipped tools are used. The feed rate and cutting speed have to be adjusted to the high hardness of the material.

Plates of the XL-XAR-500 grade receive the required properties as a result of austenitizing and  follow-on  quenching  in  special  facilities. The  heat  treatment  depends  on  the  chemical composition and the product thickness to avoid hardness losses, the steel must not be heated above 250°C.

Preferably the plasma-cutting process is used in the interest of minimum distortion and micro structure. Preheating is not normally necessary when flame – cutting thicknesses up to around 10mm. However, if the work piece temperature is below + 5°C, or the cut edges are to be cold- formed in the course of further processing, preheating to about 150°C should be considered in the interest of cold cracking resistance. If due consideration is given to the general rules for welding, this steel is weldable  both manually and automatically. To prevent cold cracking in the welded joints only welding  consumables  giving welds of very low hydrogen content should be used. To avoid preheating, use XL-HTM electrode for joining. The working temperature should not exceed 250°C. For special fabrication, contact WRTPL.

• Standard Size : 6000×1500/2000/2500
