*Special Brinell hot hardness tests were made using a 2000 kg. load and 10mm tungsten carbide ball. Both the ball and specimen were help at temperature for 20 minutes before testing.
†Special Brinell hardness measured at room temperature using a 2000 kg. load and 10mm tungsten carbide ball.
RT=Room Temperature
HRBW = Hardness Rockwell “B”, Tungsten Indentor.
HRC = Hardness Rockwell "C".
