A method for manufacturing thin-specification high-Ti wear-resistant steel NM450 comprises the steps of preparing melted iron in a blast-furnace, preprocessing the melted iron, smelting the melted iron in a converter, refining the melted steel in a LF furnace, refining the melted steel in a RH furnace, conventional slab continuous casting, heating the slab in a heating furnace, dephosphorizing the slab by high-pressure water, heating the slab in a hot continuous rolling mill, performing ultra fast cooling, reeling, flattening, heating, quenching, tempering and finishing.

Method for manufacturing thin-specification high-Ti wear-resistant steel NM450

A thin gauge wear-resistant steel sheet, including the following chemical elements expressed in percentage by weight: 0.15-0.20 wt. % of carbon; 1.2-1.8 wt. % of manganese; 0.1-0.40 wt. % of copper; 0.15-0.30 wt. % of molybdenum; 0.20-0.40 wt. % of chromium; 0.03-0.06 wt. % of niobium; 0.01-0.03 wt. % of titanium; 0.0006-0.0015 wt. % boron; less than 0.015 wt. % of phosphorus; less than 0.010 wt. % of sulphur; and the balance being ferrum and unavoidable impurities, wherein the thickness of the steel sheet is in a range of 3.0 to 8 mm.
