VASCOMAX~R C-200 (Maraging Steel)

摘要

The VascoMax C steels should be aged at 480-495 deg C (900-925 deg F) for 3-6 h, followed by air cooling. Very large cross sections should be aged for longer periods. The VascoMax C steels are processed essentially the same as the titanium-bearing 18 percent Ni maraging steels. General Characteristics: VascoMax steels are furnished in the solution-annealed condition. They are very tough, relatively soft (hardness 28--32 HRC) and, therefore, readily machined and formed. They achieve full properties through martensitic precipitation aging (hence the name maraging steels), which is a relatively simple, low-temperature heat treatment. As is true of other heat treating procedures, aging is a time/temperature-dependent reaction. Of these two factors, temperature is more important than time.
