合金結(jié)構(gòu)鋼:SCM435
執(zhí)行標(biāo)準(zhǔn): JIS G4053-2008
SCM435特性
有很高的靜力強(qiáng)度、沖擊韌性及較高的疲勞極限,淬透性較40Cr高,高溫下有高的蠕變強(qiáng)度與持久強(qiáng)度,長(zhǎng)期工作溫度可達(dá) 500℃;冷變形時(shí)塑性中等,焊接性差。
SCM435用途
用作在高負(fù)荷下工作的重要結(jié)構(gòu)件,如車輛和發(fā)動(dòng)機(jī)的傳動(dòng)件;汽輪發(fā)電機(jī)的轉(zhuǎn)子、主軸、重載荷的傳動(dòng)軸,大斷面零件。
