世界各国采用的铬轴承钢,虽然尚能满足轴承零件的基本要求,但其主要合金元素铬是我国目前稀有资源。同时铬轴承钢的某些性能及复杂的生产工艺,已远远不能满足我国机械制造和国防工业高速度发展的需要。在毛主席“备战、备荒、为人民”和“独立自主、自力更生”的伟大方针指引下,我国冶金、机械工业战线上的广大革命职工,高举毛泽东思想伟大红旗,在无产阶级文 Chromium bearing steel used in various countries in the world can meet the basic requirements of bearing components. However, its main alloying element chromium is a rare resource in our country at present. At the same time, some properties of chrome bearing steel and complicated production technology are far from meeting the needs of the rapid development of China’s machinery manufacturing and defense industry. Under the guidance of Chairman Mao’s great guideline of “preparing for war, preparing for the poor, for the people” and “being independent and self-reliant,” the vast number of revolutionary workers in the metallurgy and machinery industry in our country hold high the great red banners of Mao Zedong Thought,
