The effect of annealing temperature on the mechanical properties of extra-low carbon cold-rolled steel sheet containing P and Ti was investigated. The obtained results are as follows : 1) The observed correlation of tensile propeprties with annealing temperature is interpreted in terms of a newly proposed strengthening mechanism which differs from the previously suggested one. 2) Precipitation strengthening calculated from Ashby-Orowan model for steel sheet continuously annealed in the temperature range of 750-810℃ for 30 seconds is about 80MPa. 3) In extra-low carbon cold-rolled steel sheet containing P and Ti, effective Ti content can be expressed more realistically by Ti^<**>=Total Ti-(48/14)N-(48/32)S-Ti as (Fe, Ti)P than by the previous equation, Ti^*=Total Ti-(48/14)N-(48/32)S.
