FOllowing is heat treat way of incoloy 890
Annealing alloy 890 is accomplished by heating to a temperature between 2050 and 2200°F (1121 and 1204°C),holding for a time commensurate with section thickness, followed by rapid cooling in air or water quenching.
Alloy 890 can be sensitized by carbide precipitation when exposed to intermediate temperatures for extended periods of time.
Following of Incoloy 890 forging material heat treatment nechanical property Delivery condition :
Properties Metric Imperial
Tensile strength 62 MPa 8990 psi
Yield strength 44 MPa 6380 psi
Elongation at break 46.50% 46.50%
The finished incoloy 890 forged round bars shall be straight, sound and free from internal and surface defects viz., cracks,piping, scabs, laps, hairline cracks, etc. The bars shall be free from twists and bends.
, The surface of the bars shall be smooth without any laps, rolled in scales, etc. Dents roll marks and scratches are permitted provided their depth does not exceed half the tolerance limits specified
