Excellent video! This led me down a rabbit hole that furthered my understanding of material properties and their dependence on their atomic lattice structures. Thank you very much !
In general, the impact strength of low carbon steels decreases as temperature increases. This is due to the fact that as temperature increases, the thermal energy in the material increases, causing the atoms to vibrate more vigorously and reducing the material's ability to absorb energy without fracturing. Low carbon steels have good toughness at room temperature, which is attributed to their ductility and ability to deform before fracture. However, at elevated temperatures, the ductility of low carbon steels decreases, resulting in a reduced ability to absorb energy and resist impact. The exact temperature at which impact strength begins to decrease depends on the specific type of low carbon steel and its microstructure. Generally, the impact strength of low carbon steels begins to decrease significantly at temperatures above about 200-300°C. Therefore, it is important to consider the operating temperature of a low carbon steel component when designing for impact resistance, as higher temperatures can significantly reduce its ability to withstand impact loading.
The impact energy of SAE1010 steel at -50°C and 0°C will depend on a number of factors, including the specific testing conditions, the size and geometry of the sample, and the presence of any impurities or defects in the material. However, based on general properties of SAE1010 steel, we can make some estimates. SAE1010 steel is a low-carbon steel with good toughness and ductility, which makes it suitable for a variety of applications. At room temperature (approximately 20°C), the Charpy impact energy of SAE1010 steel is typically around 40-60 J. As the temperature decreases, the impact energy of the material generally decreases as well. This is because the lower temperature makes the material more brittle and less able to absorb energy during fracture. However, the specific impact energy values at -50°C and 0°C will depend on the specific testing conditions. It is likely that the impact energy of SAE1010 steel at -50°C will be lower than at 0°C due to the increased brittleness of the material at the lower temperature. However, without specific testing data, it is difficult to provide a more accurate estimate of the impact energy values at these temperatures.

Sir what will be the effect on impact strength with increasing temperature for low carbon steels?
In general, the impact strength of low carbon steels decreases as temperature increases. This is due to the fact that as temperature increases, the thermal energy in the material increases, causing the atoms to vibrate more vigorously and reducing the material's ability to absorb energy without fracturing. Low carbon steels have good toughness at room temperature, which is attributed to their ductility and ability to deform before fracture. However, at elevated temperatures, the ductility of low carbon steels decreases, resulting in a reduced ability to absorb energy and resist impact.

Therefore, it is important to consider the operating temperature of a low carbon steel component when designing for impact resistance, as higher temperatures can significantly reduce its ability to withstand impact loading.
Sir, For grade SAE1010 steel what is the impact energy (joule) at -50°C & 0°C ?
