Title:
METALLIC SHEET MINIMAL IN ANISOTROPY OF CHARACTERISTIC AND EXCELLENT IN SPRING LIMIT VALUE AND STRENGTH AND ITS PRODUCTION
Document Type and Number:
Japanese Patent JP2599526
Kind Code:
B
Abstract:
PURPOSE: To obtain a metallic sheet minimal in the anisotropy of characteristics and excellent in spring limit value and strength.
CONSTITUTION: A molten alloy having a composition consisting of 20-85% Cu, 0.0005-1.0% Co, 0.005-3.5% Ti, 0.1-10% Cr, 0.001-1.5% Mo, and the balance Fe is cast at ≥100°C/sec solidification cooling rate, which is subjected to primary cold rolling at ≥50%, to annealing, to secondary cold rolling at 5-70%, and then to ageing treatment. By this method, the metallic sheet in which the aspect ratio of crystalline grain is regulated to ≤20% can be produced.
