CTE of Ni-Hard

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.

TIA - Paul

RE: CTE of Ni-Hard

For a generic martensitic nickel-chromium white cast iron, with composition ranges equal or slightly broader than for ASTM A532 Class 1 Type A,
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

While were on a roll, to expand on kenvlach's info, I had found an actual Ni-Hard brochure, published by International Nickel Co "Engineering Properties and Applications of Ni-Hard" in my files  and offer the following;

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
