Abstract

The invention discloses a preparation method of a high-temperature-resisting, abrasion-resisting, corrosion-resisting and antimagnetic material, which is used for solving the problems that the existing antimagnetic material has poorer strength and hardness, is easy to corrode and has higher cost in using. The antimagnetic material is composed of the following raw materials by weight percent: 7-10% of Mn, 11-14% of Cr, 7-10% of Ni, 1-2% of V, 1-2% of Si, 1-2% of Mo, 0.5-1% of Nb, 0.1-1% of Ti, 0.3-0.4% of C and the balance of steel materials. The preparation method comprises the following steps: 1) preheating by an electric furnace; smelting by adding the steel material; 2) adding the following raw materials by weight percent: 7-10% of Mn, 11-14% of Cr, 7-10% of Ni, 1-2% of V, and smelting for 25-30 minutes; 3) then adding the following raw materials by weight percent: 1-2% of Si, 1-2% of Mo, 0.5-1% of Nb, 0.1-1% of Ti and 0.3-0.4% of C in the electric furnace, and smelting; 4) sampling and analyzing the chemical components in the electric furnace, and carrying out desulfuration, dephosphorus and carbon determination; and controlling the content of the carbon by weight percent to be 0.3-0.4%; and 5) heating and smelting by the electric furnace, and cooling; remelting and refining to remove impurities, and cooling and controlling the content of the sulfur and the phosphorus by weight percent to be less than or equal to 3%.

Description

technical field [0001] The invention relates to a method for preparing an antimagnetic material, in particular to a method for preparing an antimagnetic material with high temperature resistance, wear resistance and corrosion resistance. Background technique [0002] The anti-magnetic material is called high-nitrogen chromium-manganese stainless steel in China. This non-magnetic stainless steel was originally jointly developed by the National Iron and Steel Research Institute and Fushun Special Steel in the 1970s and 1980s. Originally developed drilling technology applied to our country. The developed W1813N and N1310 non-magnetic stainless steels are widely used in the domestic non-magnetic drill collar market. Since our country's drilling technology was very backward when developing this non-magnetic steel, and did not encounter a relatively complicated downhole environment (high temperature, corrosive environment), the corrosion resistance of W1813N and N1310 is extremel...
