中碳钢 硬度 question
Sorry cant type Chinese in this computer.I got a question comparing the hardness of alloy steel 1045 and 4140.From the published data I can see that 4140 is harder.I just wanna know why.is it related to the composition?like weight percent of carbon.
cheers
thanks for 才过正午十三点 but when I compare 1045 and 4140,1045 has a larger carbon proportion but actually its hardness is less than the 4140.why?anyone help me.

对钢材来讲,含碳量越高,强度、硬度越大,塑性、韧性越差

对不起倾斜式中在这台计算机。我有一个问题比较了1045和4140合金钢材硬度。从公布的数据，我可以看到，4140更难。我只是想知道为什么。是它涉及到组成？如重量的百分之碳。欢呼

中碳钢硬度与什么相似 中碳钢 硬度 questionSorry cant type Chinese in this computer.I got a question comparing the hardness of alloy steel 1045 and 4140.From the published data I can see that 4140 is harder.I just wanna know why.is it related to the composition?like w 40号中碳钢板的硬度是多少? 中碳钢淬火影响硬度的因素 中碳钢硬度多少?高碳钢呢?猛钢呢?花纹钢呢? 唐刀高碳钢好还是中碳钢好硬度53高碳钢硬度58左右哪个好?高碳脆吗 以中碳钢材质打造的剑品级怎么样?硬度,观赏性高不? 有低碳钢和中碳钢齿轮各一只,为使表面具有高硬度和耐磨性,应分别进行怎样的处理 什么是中碳钢 中碳钢 整体调质后硬度偏差较大整调调质后经加工,表面组织不均匀,硬度偏差较大,有谁知道产生的原因及解决办法? 铸造件为了降低硬度便于切削加工应进行什么处理?一件齿轮轴制作材料为中碳钢为了提高耐用度应进行什么处 中碳钢有哪些 45号钢是中碳钢吗 中碳钢是不锈钢么、、、 高碳钢硬度高碳钢的最低硬度是多少?我看百科全书说中碳钢硬度最高都为55,想在网上买把刀,写的高碳钢,一问说硬度才54?是高碳钢吗,再问问,开出刃以后,能砍竹子吗? 硬度 有低碳钢齿轮和中碳钢齿轮各一只,为了使齿轮表面具有高的硬度和耐磨性,应该选择何种热处理方法?并比较热处理后他们在组织和性能上的差别? 高碳钢硬还是中碳钢硬
