Effect of Temperature on Tensile and Hardness of MoldStar90
Upper Line: Demonstrates that ULTIMATE TENSILE
STRENGTH will remain constant to around 650 Degrees Fahrenheit, with
only a slight drop from 650 to 800 degrees F. Over 900 Degrees F the tensile drops more
dramatically, stabilizing again at 1,200 degrees F.
Lower Line: demonstrates that HARDNESS remains constant to
500 degrees F. Test results show that prolonged temperatures of 900 - 1,000 degrees F will
lower the hardness to roughly 20 Rockwell "C".
Effect of Temperature on Tensile and Hardness of MoldStar150
Upper Line: Demonstrates that ULTIMATE TENSILE
STRENGTH will remain constant to around 850 degrees
Fahrenheit with
only a slight drop from 950 to 1000. Over 1000 Degrees F the tensile drops more
dramatically.
Lower Line: Demonstrates that HARDNESS fluctuates in a
range above 92 Rockwell "B" up to 700 degrees Fahrenheit. Test results show that
prolonged temperatures of 900 - 1,000 degrees F will lower the hardness to 90 Rockwell
"B" or a few points below.

properties of heat treated alloys are a result of temperature exposures that are beyond
the final aging or drawing temperature of the alloy.
