Physicomechanical properties of maraging steel 06Kh14N6D2MBT
- 25 Downloads
The fine structure is the determining factor in the formation of the physicomechanical properties of steel 06Kh14N6D2MBT in all stages of aging and overaging at temperatures of 100–550°.
The ductile-brittle transition temperature Tcr determined atap=3 kgf-m/cm2 is far lower (−80°) for steel 06Kh14N6D2MBT than for pearlitic steel 12Kh2NMFA, both steels having the same fracture toughness at standard temperature.
Intensive softening of steel 06Kh14N6D2MBT begins after heating above 450°, i.e., when the overaged condition is reached.
