BS3100 Gr A3 Casting Heat treatment process: Generally all castings need to be annealed or normalized; or N+T; or OQ+T; or WQ+T
A – For anneal by heating to a temperature above the AC3 and cool in the furnace.
N – For normalize by heating to a temperature above AC3 and cool in the still air.
OQ – For quench into oil from a temperature above AC3
WQ – For Quench into water from a temperature above AC3
AH – For air harden by heating to a temperature above AC3 and cool in air at a rate fast enough to produce a hardened microstructure
T – For temper by heating to a temperature below AC1.
ST – For solution treat by heating to a temperature high enough to dissolve carbides and any into intermetallic phases followed by a rapid cool.
