PROPRIETARY 9% Nickel Steel Heat Treatments
- Heat treated either by double normalizing and tempering (NNT) or quenching and tempering (Q&T). The tempering is conducted within a restricted range, that results in the formation of a small amount (5-15%) of metallurgically stable retained austenite, which is very important in developing the superior cryogenic toughness of the steels.
Double normalized and tempered (A353):
- 1650ºF + 1450ºF + (1050 -1125ºF) 899ºC + 788ºC + (566 - 607ºC),
Quenched and tempered (A553):
- 1475ºF + (1050 - 1125ºF) 802ºC + (566 - 607ºC).
The post heat treatment within the range of 1025-1085ºF (551-583ºC), but not exceeding the tempering temperature, holding at temperature for one hour per inch of thickness, followed by cooling at a rate no less than 300ºF(167ºC) per hour. Slower cooling rates may reduce the notch toughness of the steel.
