Embodiment 1
[0025] A preparation method of a novel stainless steel material, comprising the following steps:
[0026] 1. The cast iron is smelted in a vacuum induction furnace. When the cast iron starts to melt, add chromium, silicon and molybdenum. When the cast iron is completely melted, add tungsten, manganese, nickel, boron and vanadium for smelting, and then cast into self-consumption power pole;
[0027] 2. Carry out vacuum arc remelting refining or electroslag remelting refining on the cast consumable electrode to make electroslag ingots, and the melt casting temperature is 1880°C;
[0028] 3. The electroslag ingot is pressed into a stainless steel sheet, and then the stainless steel sheet is subjected to hot forging, first annealing and second annealing in sequence to obtain a stainless steel substrate;
[0029] 4. Hot-roll the stainless steel substrate until the thickness is reduced by 2 mm, heat to 2000 ° C, keep for 50 minutes, and then deep cold-roll, so that the surface laye...

[0039] A preparation method of a novel stainless steel material, comprising the following steps:
[0040] 1. The cast iron is smelted in a vacuum induction furnace. When the cast iron starts to melt, add chromium, silicon and molybdenum. When the cast iron is completely melted, add tungsten, manganese, nickel, boron and vanadium for smelting, and then cast into self-consumption power pole;
[0041] 2. Carry out vacuum arc remelting refining or electroslag remelting refining on the cast consumable electrode to make electroslag ingots, and the melt casting temperature is 2300°C;
[0042] 3. The electroslag ingot is pressed into a stainless steel sheet, and then the stainless steel sheet is subjected to hot forging, first annealing and second annealing in sequence to obtain a stainless steel substrate;
[0043] 4. Hot-roll the stainless steel substrate until the thickness is reduced by 3 mm, heat to 2000 ° C, keep for 70 minutes, and then deep cold-roll, so that the surface laye...
