The melting methods of 07Х16Н4Д4Б - 07Х16Н4ДБ- 07Ch16N4D4B - 07Ch16N4DB forged steam turbine blade steel is as follows: The Steel shall be made using the basic electric furnace process with either the Electro-Slag Re-Melt (ESR) or Vacuum- Arc-Re-Melt(VAR) process. Alloy melting requirements shall be compatible with AMS5773E.
07Х16Н4Д4Б - 07Х16Н4ДБ is a martensitic precipitation-hardening stainless steel that provides high strength, good
corrosion resistance, good mechanical properties at temperatures up to 600°F(316°C) and good toughness in both the
longitudinal and transverse directions in both base metal and welds. Short-time,low-temperature heat treatments minimize distortion and scaling.

07Х16Н4Д4Б - 07Х16Н4ДБ forging steel turbine blade flat bars heat treat way is as follows:
07Х16Н4Д4Б - 07Х16Н4ДБ forged material is in the solution annealed condition is heated for one hour at 482 °C ± 8 °C (900 °F ± 15 °F)*and air cooled to room temperature. , it must be solution annealed after such working and before hardening. Likewise, material age hardened at one temperature cannot be rehardened at a lower
temperature without re-solution heat treating.
All surfaces of finished 07Х16Н4Д4Б - 07Х16Н4ДБ forged parts should be free of cutting lubricants, paint, adhesives, labels,and other foreign matter before any heat-treating operation is performed.
Where ductility in the hardened condition is especially important, better toughness can be obtained by raising the temperature of the hardening heat treatment. Unlike regular hardenable materials which require a
hardening plus a tempering or stress-relieving treatment, solution treatment of 07Х16Н4Д4Б - 07Х16Н4ДБ forging materual can be hardenedto the final desired properties in one operation. By heat treating at
temperatures from 482 – 621 °C (900 – 1150 °F), a wide range of properties can be attained. A heat treatment of four hours is generally used for all hardening heat treatments except 482 °C (900 °F), forwhich a one-hour treatment is used.
Mechanical properties of 07Х16Н4Д4Б - 07Х16Н4ДБ forged round bars shall be tested at room temperature (23 ± 5degree),
