What is the minimum carbon content in carbon steel in order

What is the minimum carbon content in carbon steel in order for the material to have a Charpy V notch impact energy of at least 50 joules at 100C

Solution

>> The minimum carbon content in carbon steel in order for the material to have a Charpy V notch impact energy of at least 50 joules at 100C is 0.53 %

>> Increasing carbon percentage will reduce the fracture toughness....
