Martensite stainless steel material for electric shaver head

Abstract

The invention discloses a martensite stainless steel material for an electric shaver head. The martensite stainless steel material is formed by melting with a conventional melting method or fusing by taking the stainless steel material SUS420J2 as a mother material and removing impurities of the materials by using an electrolytic separation method. The material comprises the following components in percentage by weight: 0.33-0.45 percent of C, less than or equal to 1.00 percent of Si, less than or equal to 1.50 percent of Mn, less than or equal to 0.04 percent of P, less than or equal to 0.015 percent of S, 15.50-17.50 percent of Cr, 0.80-1.30 percent of Mo, less than or equal to 1.00 percent of Ni and the balance of Fe. Test shows that the material has the characteristics of high wear resistance, strong corrosion resistance, stable thermal treatment characteristic, excellent grinding processing performance and the like and is an excellent material for producing the electric shaver head.

Description

technical field [0001] The present invention relates to a martensitic stainless steel material for electric shaver heads. Background technique [0002] Chinese patent CN1861826A disclosed a corrosion-resistant and wear-resistant tool steel product on November 15, 2006. The product is made by hot isostatic pressing of nitrogen-atomized pre-alloyed powder particles. In terms of weight percentage, the powder particles are basically composed of the following substances: C: 2.0-3.5; SI: up to 1.0; MN: up to 1.0; CR: 12.0-16.0; MO: 2.0-5.0; V: 6.0-11.0 ; NB: 2.0-6.0; CO: 1.5-5.0; N: 0.05-0.30; and the balance is essentially iron and incidental impurities. The product is made by hot isostatic pressing of pre-alloyed high-chromium, high-vanadium and high-niobium powder particles atomized by nitrogen gas. The alloy is characterized by a high resistance to wear and corrosion, which makes it particularly suitable for use in the manufacture of parts exposed to severe wear and corrosio...

AI Technical Summary

Problems solved by technology

For a long time, there is no special material suitable for the shaver head disclosed in the prior art. Domestic shaver companies can only use stainless steel materials similar to SUS420J2 to make the head. Due to the poor material of the head, corrosion resistance, The wear resistance and strength cannot meet the quality requirements of high-speed moving razor heads, resulting in the overall low quality of domestic razors, often having problems such as poor shaving sharpness, poor sound quality and short service life, which seriously restricts The development of the razor industry
