temperature affects on steel hardness
CONCLUSIONS. The present study of the effect of temperature on the electrodeposition of chromium on 1045 steel showed that the hardness increases while the grain size of the chromium deposited decreased with increase in temperature. Between 50 Â°C and 60 Â°C the results showed barely perceptible differences.
Fig 4 Effect of nitrogen on strain ageing index of steel. Effect during welding â Nitrogen generally affects the toughness of the heat affected zone (HAZ) of welded steel. Since the weld metal should not be weaker in a welded structure, the role of nitrogen is important. The loss of toughness is normally known as HAZ embrittlement.
