You are an engineer for a steel plant. You are presented with a piece of steel from your rival plant. You investigate the microstructure and find it to contain 60 % ferrite and 40% martensite, and the martensite contains 0.5% carbon. Based on this information, reverse engineer the nominal composition and starting temperature used by your rival. You may assume the composition of ferrite to be 0.022%. (Round the composition to 2 decimal places, and the temperature to the nearest 25 degrees Celsius)

Question
You are an engineer for a steel plant. You are presented with a piece of steel from your rival plant. You
investigate the microstructure and find it to contain 60 % ferrite and 40% martensite, and the
martensite contains 0.5% carbon.
Based on this information, reverse engineer the nominal composition and starting temperature used by
your rival.
You may assume the composition of ferrite to be 0.022 %.
(Round the composition to 2 decimal places, and the temperature to the nearest 25 degrees Celsius)
O 0.31wt% C at 725 Celsius
O 0.21wt% C at 725 Celsius
0.26wt% C at 775 Celsius
O 0.26wt% Cat 725 Celsius
O 0.21wt% C at 775 Celsius
0.31wt% Cat 775 Celsius
