沙蒲崔3224轴材质4140是什么钢啊?好像是美国标准
沙矩闸17672763374 ______ 4140是美国钢材牌号,相当于我国的42CrMo,属于合金结构钢.

沙蒲崔3224sae4140是什么材料 -
沙矩闸17672763374 ______ SAE4140(标准SAE J404)为合金钢与我国的材质42CrMo(标准GB/T 3077)最接近.

沙蒲崔3224AISI 4140 PRE - HARDENED STEEL是什么材料? -
沙矩闸17672763374 ______ AISI4140属于美标高强度合金结构钢,执行标准:ASTM A29/A29M-04 AISI4140化学成分如下图:AISI 4140 PRE-HARDENED STEEL是预硬型高强度合金结构钢.

沙蒲崔3224SCM44O是什么材料? -

沙蒲崔32244140钢材与45号钢材对比 -
沙矩闸17672763374 ______ 4140是合金钢,强度、淬透性高,韧性好,淬火时变形小,高温时有高的蠕变强度和持久强度. 化学成份: 碳 C :0.38~0.43 硅 Si:0.15~0.35 锰 Mn:0.75~1.00 硫 S :≤0.040 磷 P :≤0.030 铬 Cr:0.80~1.10 镍 Ni:≤0.030 铜 Cu:≤0.030 钼 Mo:0.15~0.25...

沙蒲崔3224AS1444 - 4140是什么材质?请大家帮帮忙,谢谢 -
沙矩闸17672763374 ______ 美国的牌号; 对应的中国牌号是42CRMO;属于合金结构钢; 化学成分质量分数:C:0.38-0.45;SI:0.17-0.37;MN:0.5-0.8;CR:0.9-1.2;MO:0.15-0.25;
