MANUFACTURING METHOD FOR MULTI-ELEMENT ALLOYED, HIGH-STRENGTH, HIGH-WEAR-RESISTANT STEEL AND HOT-ROLLED PLATE

摘要

This invention provides a manufacturing method of a multi-component alloying steel with high strength and high wear-resistance and a hot rolled plate thereof. The weight percentages of the chemical composition of the wear-resistant steel above is as follows: C: 1.0-1.2%, Si: 0.6-1.0%, Mn: 8.0-10.0%, P 0.02%, S 0.02%, Cr: 1.5-2.5%, Mo: 0.2-0.5%, V: 0.6-1.0%, Nb: 0.02-0.06%, Ti: 0.01-0.1%, Al: 0.03-0.08%, and the rest are Fe and unavoidable impurities. The manufacturing process of the hot rolled plate of the wear-resistant steel includes the steel making, continuous casting, heating, hot rolling and heat treatment.
