ASTM A487 4C
ASTM A487 4C
(OP)
I am looking for recommendations on the heat treatment of ASTM A487 4C. The ASTM specification gives 1600F for austenitizing treatment and 1150F for the tempering heat treatment. I have seen normalizing and austenitizing performed on this material, up to 1700F, and tempering up to 1200F. Does anyone have experience with the heat treatment of this material?





RE: ASTM A487 4C
So, you will have a normalized (austenitize and air cool) and tempered heat treatment condition for these castings. The liquid medium for cooling would be as agreed upon to facilitate cooling of larger castings.
These castings are weldable and widely used in industry.
