Pearlite performance main performance
The performance of pearlite is between ferrite and cementite, and the toughness is better. Its tensile strength is 750 ~ 900MPa, 180 ~ 280HBS, elongation is 20 ~ 25%, impact energy is 24 ~ 32J. The mechanical properties are between ferrite and cementite, with high strength, moderate hardness, good plasticity and toughness σb=770MPa, 180HBS, δ=20%~35%, AKU=24~32J).
The comprehensive mechanical properties of pearlite are better than those of ferrite or cementite alone. The mechanical properties of pearlite are between ferrite and cementite, and the strength and hardness are moderate and not brittle, because the amount of cementite in the pearlite is much less than the amount of ferrite.
