表中( )内的数字不常用
洛氏硬度计上刻度A、B、C是使用钻石圆锥压凹器(brale)

硬度换算公式:

1. 萧氏硬度(HS)=勃式硬度(BHN)/10+12

2. 萧式硬度(HS)=洛式硬度(HRC)+15

3. 勃式硬度(BHN)= 洛克式硬度(HV)

4. 洛式硬度(HRC)= 勃式硬度(BHN)/10-3

BHN/10~HRC(BHN在300~600间适用)

BHN/6~HS(一般钢材)

HV~BHN+20(H<450适用)

T.S.(kgf/cm2)~35*BHN(一般钢材)

硬度测定范围:

HS<100

HB<500

HRC<70

淬火：把金属工件加热到一定温度,然后突然浸在水或油中使其冷却,以增加硬度

回火：把淬硬的钢或铸铁在比前次淬火温度低得多的温度中加热使软化

退火；使退火给（玻璃或金属）加热并使之慢慢冷却以使之变硬并减少易碎性
