FV 520B机械性能

1050 ℃ solid solution treatment + 850 ℃ intermediate + 470 ℃ ageing FV520B steel strength reached the maximum when = FV520B

FV520B has excellent mechanical performance at low temperature, under high temperature tempering has good tensile properties at low temperature.When the temperature of the cooling liquid nitrogen is still keep the room temperature mechanical properties.This is why?Because FV520B austenitic steel has the inverter performance.Low temperature deformation, austenite into martensite, intensity is greatly raised.Different inverter of austenite, the strength is different also.
