Abstract

The present invention provides a steel plate with great heat and abrasion resistance and a manufacturing method thereof. The steel plate comprises the following chemical composites, in percentage by weight: 0.10-0.30% of C, 0.10-1.50% of Si, 0.50-2.00% of Mn, 0-0.015% of P, 0-0.010% of S, 0.2-2.00% of Cr, 0.10-1.50% of Mo, 0-1.00% of Ni, 0-0.10% of V, 0-0.10% of RE, 0-1.00% of W, 0.010-0.080% of Al, 0.0005 -0.0040% of B, 0-0.080% of Ti, 0.0010-0.0080% of Ca, 0-0.0080% of N, 0-0.0080% of O, 0-0004% of H and the balance being Fe and inevitable impurities. The mechanical properties of the steel plate are that the Brinell hardness is greater than 360HB, and the 500 DEG C tensile strength is more than 1000MPa. The steel plate obtained by the various components through processes such as quenching and tempering has excellent mechanical properties and abrasion resistance, and is particularly suitable for various mechanical parts which are easy to wear while working under high temperature.

Description

Technical field [0001] The invention relates to wear-resistant steel, in particular to a heat-resistant wear-resistant steel plate and a manufacturing method thereof; its mechanical properties: Brinell hardness is greater than 360HB, and tensile strength at 500°C is greater than 1000MPa. Background technique [0002] Wear-resistant steel plates are widely used in engineering, mining, agriculture, cement production, ports, electric power, metallurgy and other mechanical products that require particularly harsh working conditions, high strength and high wear resistance. Such as bulldozers, loaders, excavators, dump trucks and grabs, stackers and reclaimers, conveying curved structures, etc. [0003] In recent decades, the development and application of wear-resistant steel have developed rapidly. At present, low-alloy martensitic wear-resistant steel is commonly used. This type of wear-resistant steel mainly improves the mechanical properties of wear-resistant steel by increasing th...
