Descriptions
Principle: the chromium - resistant composite steel plate is composed of Q235 base plate + chromium alloy wear-resistant layer.
Method: the wear-resistant layer adopts open arc welding or submerged arc welding
Performance: special self - protection - arc welding wire is uniformly fused to different thickness of steel substrate
Composition: the composite wear-resistant laminated plate made from the composite alloy. Wear-resistant layer material is similar to high chromium cast iron
Hardness: surface hardness HRC: 58-62
Thickness: can produce different thickness according to different usage situation. Common specifications: 6+ 4, 6+ 6, 8+5, 10+8mm,etc
Details
Properties: 1. Dual performance with high hardness material and toughness material, can withstand moderate impact and vibration, prevent shedding.
2. Compared with other kinds of alloy steel plate, casting wear-resisting board, ceramic, cast stone, rubber and polyurethane, it has good wear resistance, high toughness and arbitrary machining.
3. Convenient installation, cutting, welding, punching and bending.
4. Used for different occasions, the wear-resisting property is 10 -- 15 times that of ordinary wear-resistant materials.
5. High temperature resistance, can be used in 550 degrees, does not affect wear resistance.
