Stainless steel material for blade of electric razor

Abstract

The invention discloses a stainless steel material for a blade of an electric razor. Calculated in percentage by weight, the material comprises the following alloy element components: 0.15-0.2% of C (carbon), not more than 1.00% of Si (silicon), not more than 1.50% of Mn (manganese), not more than 0.04% of P (phosphorus), not more than 0.015% of S (sulfur), 13.50-15.50% of Cr (chromium), 0.80-1.30% of Mo (molybdenum), not more than 1.00% of Ni (nickel), 1.5-2.5% of Cu (copper) and the balance of Fe (iron). The hardness of the stainless steel material disclosed by the invention can achieve HV540-620 and be in line with the hardness requirement of the blade of the electric razor through three-stage heating quenching at the temperature of 400 DEG C, 850 DEG C and 1050 DEG C and tempering treatment at the temperature of 200 DEG C-400 DEG C. In addition, the material disclosed by the invention has the characteristics of high abrasion resistance, strong corrosion resistance, stable heat treatment property, excellent grinding processing performance and the like, the comprehensive performance of the material is better than that of a cutter material which is imported from abroad, and the material is suitable for production needs of large-batch domestic cutters and can get obvious economic benefits, so that the material is of an excellent new material for the blade of the electric razor.

Description

technical field [0001] The present invention relates to a stainless steel material for electric razor blades. Background technique [0002] The cutter head and knife net (collectively referred to as cutting tools) of the electric shaver are the core parts of the electric shaver. For a long time, there is no special material suitable for razor blades in China. Domestic razor companies can only use martensitic stainless steel materials similar to SUS420J2 to make razor blades. Cracks are prone to appear in the middle, so the use is limited. Moreover, its corrosion resistance, wear resistance, and strength cannot meet the quality requirements of high-speed moving razor knives, so the overall quality of domestic razors is not high, the shaving sharpness is poor, the sound quality is not good, and the service life is short. And other problems have seriously restricted the development of the shaver industry. Contents of the invention [0003] The technical problem to be solve...

For a long time, there is no special material suitable for razor blades in China. Domestic razor companies can only use martensitic stainless steel materials similar to SUS420J2 to make razor blades. Cracks are prone to appear in the middle, therefore, the use is limited

Moreover, its corrosion resistance, wear resistance, and strength cannot meet the quality requirements of high-speed moving razor knives, so the overall quality of domestic razors is not high, the shaving sharpness is poor, the sound quality is not good, and the service life is short. And other problems, seriously restricted the development of the shaver industry
