The Performance requirements of low alloy structural steel, en 10025-6 S690QL equivalent ASTM:(1) High strength: generally, the yield strength is above 300Mpa.(2) High toughness: the elongation is required to be 15% - 20%, and the room temperature impact toughness is greater than 600kJ/m ~ 800kJ/m. For large welded components, higher fracture toughness is required.(3) Good weldability and cold forming property.(4) Low cold brittle transition temperature. (5) Good corrosion resistance.

The wear-resistant plate has the main advantages of high strength and hardness, good toughness, en 10025-6 S690QL equivalent ASTM high tensile strength, good material wear-resistance, long service life and low cost. In order to verify the wear-resistant life of the high wear-resistant composite steel plate applied in the field, the comparative industrial test of en 10025-6 S690QL equivalent ASTM wear-resistant with the ordinary carbon plate was carried out on the reclaimer of Jigang raw material plant, and the effect is good.
