CTE of Ni-Hard
CTE of Ni-Hard
(OP)
Can anyone tell me or point me in the direction of where I can find the coeffiecient of thermal expansion for "Ni-Hard" white irons. Specifically ASTM A532 Class 1 Type A. I have searched to no avail.

RE: CTE of Ni-Hard
CTE = 8-9 x 10-6 m/m/oC for a temperature range 10-260oC
= 4.4-5 x 10-6 in/in/oF for a temperature range 50-500oF.
From ASM Metals Reference Book, 3rd Edn., pp. 270-271.
RE: CTE of Ni-Hard
Type 1 regular
CTE 50-200 deg F 4.5-5.0
50-500 deg F, 6.3-6.6 X 10-6
50-800 deg F 6.8-7.1
