一种不锈砂及其制备方法
Abstract:
一种不锈砂及其制备方法，属于金属磨料生产技术领域。以质量百分比计，包含以下成份：C 0.7~3.5%、Si 0.1~2.0%、Mn 0.35~2.0%、S 0.0001~0.1%、P 0.0001~0.1%、Cr 10.5~35%、Mo 0.001~2.0%、Ti 0.001~2.0%、V 0.001~2.0%、Ni 0.001~9.0%、Cu 0.05~2.0%、Nb 0.0001~0.5%、和Al 0.001~0.05%，其余为Fe。该不锈砂耐磨性和耐腐蚀性能好、表面硬度高，打磨过程中不易破碎生锈，具有较长的使用寿命。采用本发明制备方法制得的不锈砂，能够进一步提高不锈砂的耐疲劳破坏能力，提高耐磨性能。
Abstract(English):

The invention discloses stainless sand and a production method thereof, and belongs to the technical field of production of metal abrasives. The stainless sand comprises, in mass percentage, 0.7-3.5% of C, 0.1-2.0% of Si, 0.35-2.0% of Mn, 0.0001-0.1% of S, 0.0001-0.1% of P, 10.5-35% of Cr, 0.001-2.0% of Mo, 0.001-2.0% of Ti, 0.001-2.0% of V, 0.001-9.0% of Ni, 0.05-2.0% of Cu, 0.0001-0.5% of Nb, 0.001- 0.05% of Al and the balance Fe. The stainless sand is good in abrasive resistance and corrosion resistance, high in surface hardness and long in service life and does not get broken or rusted in the polishing process. The fatigue rupture resistance of the stainless sand produced through the production method can be further improved, and the abrasive resistance can be improved.
