国家标准硬度转换表
国家标准硬度转换表
硬度換算公式: 1.肖氏硬度(H S)=勃式硬度(B H N)/10+12 2.肖式硬度(H S)=洛式硬度(H R C)+15 3.勃式硬度(B H N)=洛克式硬度(H V) 4.洛式硬度(H R C)=勃式硬度(B H N)/10-3 洛氏硬度H R C和布氏硬度H B等硬度对照区别和换算 硬度：是衡量材料软硬程度的一个性能指标。硬度试验的方法较多，原理也不相同，测得的硬度值和含义也不完全一样。最普通的是静负荷压入法硬度试验，即布氏硬度(H B)、洛氏硬度(H R A，H R B，H R C)、维氏硬度(H V)，橡胶塑料邵氏硬度(H A,H D)等硬度其值表示材料表面抵抗坚硬物体压入的能力。最流行的里氏硬度（H L）、肖氏硬度(H S)则属于回跳法硬度试验，其值代表金属弹性变形功的大小。因此，硬度不是一个单纯的物理量，而是反映材料的弹性、塑性、强度和韧性等的一种综合性能指标。 1、钢材的硬度：金属硬度(H a r d n e s s)的代号为H。按硬度试验方法的不同， ●常规表示有布氏（H B）、洛氏（H R C）、维氏（H V）、里氏（H L）硬度等，其中以H B及H R C较为常用。 ●H B应用范围较广，H R C适用于表面高硬度材料，如热处理硬度等。两者区别在于硬度计之测头不同，布氏硬度计之测头为钢球，而洛氏硬度计之测头为金刚石。 ●H V-适用于显微镜分析。维氏硬度(H V)以120k g以内的载荷和顶角为136°的金刚石方形锥压入器 压入材料表面，用材料压痕凹坑的表面积除以载荷值，即为维氏硬度值(H V)。 ●H L手提式硬度计，测量方便，利用冲击球头冲击硬度表面后，产生弹跳；利用冲头在距试样表面1m m 处的回弹速度与冲击速度的比值计算硬度，公式：里氏硬度H L=1000×V B（回弹速度）/V A（冲击速度）。 ●目前最常用的便携式里氏硬度计用里氏（H L）测量后可以转化为：布氏（H B）、洛氏（H R C）、维氏（H V）、肖氏（H S）硬度。或用里氏原理直接用布氏（H B）、洛氏（H R C）、维氏（H V）、里氏（H L）、肖氏（H S）测量硬度值。 时代公司生产的T H系列里氏硬度计就有此功能，是传统台式硬度机的有益补充！”（详细情况请点击《里氏硬度计T H140/T H160/H L N-11A/H S141便携式系列》） 洛氏硬度(H R C)一般用于硬度较高的材料，如热处理后的硬度等等。 2、H B-布氏硬度：一般用于材料较软的时候，如有色金属、热处理之前或退火后的钢铁。布式硬度 (H B)是以一定大小的试验载荷，将一定直径的淬硬钢球或硬质合金球压入被测金属表面，保持规定时间，然后卸荷，测量被测表面压痕直径。布式硬度值是载荷除以压痕球形表面积所得的商。一般为：以一定的载荷(一般3000k g)把一定大小(直径一般为10m m)的淬硬钢球压入材料表面，保持一段时间，去载后，负荷与其压痕面积之比值，即为布氏硬度值(H B)，单位为公斤力/m m2(N/m m2)。（关于布 式硬度(H B)详细情况请点击《布氏硬度机(计)H B-3000B/T H600》）

硬度简介和几种硬度的转换表
硬度分为维氏、洛氏、布氏、里氏、努氏等等。不管用是什么硬度，都是在同一标准前提下对比硬度的相对大小。其中最常用的是洛氏和布氏，但布氏压痕较大，破坏试样，不用于产品上，只用于试验试件上，洛氏最常用，由于压痕小，可以直接在产品上打硬度，现在许多厂家都有在线的洛氏硬度计，洛氏硬度又分几个系列，比如HRA、HRB、HRC。。。。等等，软硬范围不同（压头的尺寸和材料不同），比如一般的较软的用HRC，较硬的的用HRA，就象人的身高，0.8米，用1米的尺子就可以测量，1.8米需要2米的尺子，各种材料的硬度不同，范围较大，所以不同的材料对应用不同的系列，硬度的主要目的是验证强度（硬度试验方便），而硬度和强度的转换主要基于经验。 1.洛氏硬度 是以压痕塑性变形深度来确定硬度值指标。以0.002毫米作为一个硬度单位。当HB>450或者试样过小时，不能采用布氏硬度试验而改用洛氏硬度计量。它是用一个顶角120°的金刚石圆锥体或直径为1.59、3.18mm的钢球，在一定载荷下压入被测材料表面，由压痕的深度求出材料的硬度。根据试验材料硬度的不同，分三种不同的标度来表示：HRA：是采用60kg载荷和钻石锥压入器求得的硬度，用于硬度极高的材料(如硬质合金等)。HRB：是采用100kg载荷和直径1.58mm淬硬的钢球，求得的硬度，用于硬度较低的材料(如退火钢、铸铁等)。HRC：是采用150kg载荷和钻石锥压入器求得的硬度，用于硬度很高的材料(如淬火钢等)。 2.布氏硬度 布氏硬度(HB)一般用于材料较软的时候，如有色金属、热处理之前或退火后的钢铁。洛氏硬度(HRC)一般用于硬度较高的材料，如热处理后的硬度等等。布氏硬度(HB)是以一定大小的试验载荷，将一定直径的淬硬钢球或硬质合金球压入被测金属表面，保持规定时间，然后卸荷，测量被测表面压痕直径。布氏硬度值是载荷除以压痕球形表面积所得的商。一般为：以一定的载荷将一定大小的淬硬钢球压入材料表面，保持一段时间，去载后，负荷与其压痕面积之比值，即为布氏硬度值(HB)，单位为公斤力/mm2 (N/mm2)。测试载荷与测试钢球的直径需根据材料的实际性能再确定。 3.维氏硬度 维氏硬度试验方法是英国史密斯（，维氏硬度试验测量范围较宽，从较软材料到超硬材料，几乎涵盖各种材料。 4.里氏硬度 里氏硬度是以HL表示，里氏硬度测试技术是由瑞士狄尔马，里伯博士发明的，它是用一定质量的装有碳化钨球头的冲击体，在一定力的作用下冲击试件表面，然后反弹。由于材料硬度不同，撞击后的反弹速度也不同。在冲击装置上安装有永磁材料，当冲击体上下运动时，其外围线圈便感应出与速度成正比的电磁信号，再通过电子线路转换成里氏硬度值。 5.肖氏硬度 简称HS。表示材料硬度的一种标准。由英国人肖尔(Albert F.Shore)首先提出。应用弹性回跳法将撞销从一定高度落到所试材料的表面上而发生回跳。撞销是一 1
