The metal structure of 1Cr5Mo is martensite, which has good oxidation resistance at about 650 degrees Celsius, good thermal strength below 600 degrees Celsius, and good shock absorption and thermal conductivity. Widely used in steam turbines. However, this type of steel has a greater tendency to harden and has poor welding performance. 5-70MM thick, can be customized for rolling futures. In electromagnetism, when two magnets or magnets attract or repel each other, or when a current-carrying wire generates a magnetic field around it, causing the magnetic needle to deflect, or when a closed circuit moves in an uneven magnetic field, a current will appear in the closed circuit. , these are phenomena related to magnetism. All phenomena related to magnetism are also related to magnetic fields.
