SPECIAL STEEL AS MATERIAL FOR MACHINING STEEL AND MANUFACTURING PROCESS THEREOF

摘要

The present invention is carbon (C) 0.60 to 0.90 weight%, silicon (Si) 0.50 to 1.50 wt%, manganese (Mn) 0.40 to 1.00% by weight, nickel (Ni) 6.0 to 7.5% by weight, chromium (Cr) 23 to 28 wt.%, molybdenum (Mo) 0.50 to 2.00% by weight and the balance of iron (Fe) and the other consisting of the inevitable impurities, the steel as a Mechanism for a processing machine special steel material, to a production method and its use. ; Special steel of the present invention also exhibits excellent heat resistance, corrosion resistance, wear resistance, shock resistance, oxidation resistance, and precision to be used for a long time at a high temperature, high pressure and high shock environment. ; Special steel, induction guide, cutting knives, heat resistance, wear resistance, impact resistance
