7.
Which of the following statements is suitable to describe the mechanical properties of low carbon
steels and high carbon steels without cold working treatment?
(a)
Low carbon steels containing ferrite and pearlite phases generally have lower tensile strength
than high carbon steels.
(b)
Low carbon steels containing cementite and pearlite phases generally have lower hardness than
high carbon steels.
