对新型不锈轴承钢 6Cr14Mo和不锈钢 9Cr18的退火、淬回火组织和硬度以及接触疲劳寿命等方面进行了研究 ,结果表明 :新型不锈轴承钢中共晶碳化物含量明显减少 ,热处理后的硬度高 ,耐磨性好 ,接触疲劳寿命和可靠性明显好于 9Cr18钢。附图 5幅 ,表 3个。
The new stainless steel bearing steel 6Cr14Mo and stainless steel 9Cr18 annealing, quenching and tempering the organization and hardness and contact fatigue life and other aspects were studied. The results show that: the new stainless steel bearing carbide eutectic carbide content was significantly reduced after heat treatment, high hardness , Good wear resistance, contact fatigue life and reliability significantly better than 9Cr18 steel.
