16CRMO44/ DIN 1.7337 QUALITY ALLOY STEEL

16CrMo44/DIN 1.7337 steel  is a low-alloy steel containing chromium and molybdenum as strengthening elements.Similar to the Chinese grade 15CrMo,16CrMo44 steel has good process performance and welding performance, and has a high lasting strength at a temperature of 500 to 550 °C.Once the temperature exceeds 550 °C, its oxidation resistance becomes poor, and the creep strength decreases significantly.

16CrMo44 steel is generally used in the quenched and tempered condition.It is used to manufacture high and medium pressure steam conduits, headers, superheaters and supporting forgings.

Heat Treatment
Normalizing For 16CrMo44
1.Nominal normalizing temperature:840-890°C
2.Hold the temperature for several hours
3.Cooling in the air

Annealing  For 16CrMo44
1.Nominal Annealing temperature:680-720°C
2.Cool slowly in the furance
3.Maximum Brinell hardness of 217

Quenching and Tempering(QT)  For 16CrMo44
