| description | The invention relates to high-strength wear-resistant steel for a track shoe and a preparing method for the high-strength wear-resistant steel, and belongs to the metallurgy technology. The high-strength wear-resistant steel is mainly invented for solving the problems that existing steel for the track shoe is low in yield strength, extension strength and hardness and poor in wear-resistant performance. The high-strength wear-resistant steel for the track shoe comprises, by weight percentage, 0.21%-0.26% of C, 0.15%-0.30% of Si, 0.80%-1.20% of Mn, not larger than 0.03% of P, not larger than 0.015% of S, 0.0005%-0.003% of B,0.30%-0.50% of Cr and the balance iron and trace impurities. The manufacturing method includes the following steps of molten iron receiving, electric furnace smelting, tapping alloying, LF refining, VD vacuum treatment, continuous casting and rolling. The high-strength wear-resistant steel has the advantages that the yield strength, the extension strength and the hardness are high, and the w |
