_NOTE.--These melting points are for average compositions and conditions.
The exact proportion of elements entering into the metals affects their
melting points one way or the other in practice._
TENSILE STRENGTH OF METALS
Alloy steels can be made with tensile strengths as high as 300,000 pounds
per square inch. Some carbon steels are given below according to "points":
Pounds per Square Inch
Steel, 10 point................ 50,000 to 65,000
20 point..................... 60,000 to 80,000
40 point..................... 70,000 to 100,000
60 point....
