摘要

PROBLEM TO BE SOLVED: To provide a cold rolled steel sheet, a galvanized cold rolled steel sheet and hot-dip galvannealed cold rolled steel sheet, each having high Young's modulus in all of a rolling direction, a rolling 45° direction and a rolling right angle direction.SOLUTION: There is provided the high Young's modulus cold rolled steel sheet having a chemical composition containing, by mass%, C:0.0005 to 0.01%, Si:1.50% or less, Mn:0.50 to 1.50%, P:0.08% or less, S:0.01% or less, Al:0.10% or less, N:0.006% or less, Ti:0.0025 to 0.10%, and B:0.0005 to 0.005% so as to satisfy the following formulae, and the balance iron with inevitable impurities. Ti(mass%)/C(mass%)5 Ti=Ti(mass%)+48/93×Nb(mass%)-48/14×N(mass%)-48/32×S(mass%)
