iron-carbon alloy with low carbon content, a little manganese and only residual
amounts of other impurities
iron-carbon alloy with normally between 3.1 and 4.0 wt% carbon and between

, Lesson 6 Quiz: MATSE 81 (Merged SP18)
iron-carbon alloy with between 2.5 and 4.0 wt% carbon and between 1.0 and
3.0 wt% of silicon
Question 2 pts
Which of these statements is the best description of the properties of high-
carbon steel?
wide range of mechanical properties with excellent resistance to corrosion
comparatively weak and brittle in tension but stronger and more ductile under
compression
extremely hard and very brittle
high thermal conductivity, resistance to fracture due to rapid temperature
changes, and reduced oxidation at elevated temperatures
Correct! hardest, strongest, and least ductile of the carbon steels
relatively soft and weak but possesses outstanding ductility and toughness,
and are the least expensive to produce
