Abstract

A STEEL SHEET HAVING A LOW PROPORTIONAL LIMIT AND A METHOD FOR MANUFACTURING THE STEEL SHEET ARE PROVIDED. A COLD-ROLLED SHEET HAVING A COMPOSITION OF C: 0.10% OR LESS, SI: 0.05% OR LESS, MN: 0.1% TO 1.0%, P: 0.05% OR LESS, S: 0.02% OR LESS, AL: 0.02% TO 0.10%, AND N: LESS THAN 0.005%, BASED ON MASS PERCENT, A REMAINDER OF FE, AND INCIDENTAL IMPURITIES IS SUBJECTED TO AN ANNEALING TREATMENT OF HEATING THE COLD-ROLLED SHEET AT AN ANNEALING TEMPERATURE IN THE RANGE OF 730°C TO 850°C FOR 30 S OR MORE AND THEN COOLING THE COLD-ROLLED SHEET TO A TEMPERATURE OF 600°C OR LESS AT AN AVERAGE COOLING RATE OF 5°C/S OR MORE, FORMING A COLD-ROLLED AND ANNEALED SHEET HAVING A STRUCTURE MAINLY COMPOSED OF A FERRITE PHASE HAVING AN AVERAGE GRAIN SIZE D IN THE RANGE OF 5 TO 30 µM. THE COLD-ROLLED AND ANNEALED SHEET IS SUBJECTED TO SKIN PASS ROLLING USING A REDUCTION ROLL HAVING A SURFACE ROUGHNESS RA OF 2.0 µM OR LESS AT A SKIN PASS ROLLING ELONGATION PERCENTAGE R (%) IN THE RANGE OF (0.05 TO 0.20) D (%), WHEREIN D DENOTES THE AVERAGE GRAIN SIZE (µM) OF THE COLD-ROLLED AND ANNEALED SHEET. THIS PRODUCES A COLD-ROLLED STEEL SHEET HAVING A PROPORTIONAL LIMIT OF 150 MPA OR LESS. A HOT-DIPPED GALVANIZED LAYER, A GALVANNEALED LAYER, OR AN ELECTROGALVANIZED LAYER MAY BE FORMED ON THE SURFACE.
