Abstract

The invention provides an alloy steel used for high-temperature electric resistance furnace. The alloy steel is composed of the following components in percentage by weight: 0.25 to 0.68% of C, 2.4 to 5.6% of Mn, 0.40 to 0.65% of Si, not more than 0.03% of P, not more than 0.025% of S, not more than 0.12% of N, 12.3 to 13.1% of Cr, 1.4 to 2.7% of Ni, 0.25 to 0.30% of V, 0.9 to 1.2% of Mo, 2.5 to 3.2% of W, and the balance being Fe. The alloy steel used for high-temperature electric resistance furnace has a good high-temperature antioxidant performance and oxidant resistant performance, excellent wear resistant property, heat resistance, and antioxidant property, and a high corrosion fatigue resistant performance. Moreover the thermal conductivity, conductivity, and overheating sensitivity of the alloy steel are all reduced.

Description

technical field [0001] The invention relates to an alloy steel, in particular to an alloy steel used in a high-temperature resistance furnace. Background technique [0002] For alloy steel such as steel plate and section steel used in high temperature resistance furnace, due to the high temperature of high temperature resistance furnace, the alloy steel is required to have good heat resistance, wear resistance, heat strength and corrosion fatigue resistance, so as to ensure that the alloy steel can be used normally for a long time , At the same time, the overall performance of the alloy steel affects the safety of the production and use process of the high temperature resistance furnace. Therefore, the above problems should be considered and solved in the design and production process of the alloy steel used in the high temperature resistance furnace. Contents of the invention [0003] The purpose of the present invention is to provide an alloy steel for high temper...
