SUJ2軸承鋼介紹:
日本JIS標(biāo)準(zhǔn)SUJ2高碳鉻軸承鋼
SUJ2高碳鉻軸承鋼,可全硬處理,硬度可達(dá)HRC58-61,具備了軸承的耐磨性,也加強(qiáng)了鋼性,加工性佳,并可直接加工成型,使用模次高于SKD-61(HRC52)全硬體2-3倍。在淬火、回火時(shí)尺寸變化不大,抗疲勞性能相當(dāng)好.
綜合性能良好。淬火和和回火后硬度高而均勻,耐磨性、接觸疲勞強(qiáng)度高。熱加工性好,球化退火后有良好的可加工性,但對(duì)形成白點(diǎn)敏感。
用途:
用于一般塑膠模具,汽車,機(jī)床軸承,鋼球,滾子,軸套,冷軋.
制造內(nèi)燃機(jī)。電機(jī)車、機(jī)床、拖拉機(jī)、軋鋼設(shè)備、鉆探機(jī)、鐵道車輛以及礦山機(jī)械等傳動(dòng)軸上的鋼球、滾子和軸套等。
