Title:
DEAD SOFT STEEL SHEET HAVING HIGH SUITABILITY TO CHEMICAL CONVERSION TREATMENT
Document Type and Number:
Japanese Patent JPS6126756
Kind Code:
A
Abstract:
PURPOSE: To obtain a dead soft steel sheet having high suitability to chemical conversion treatment by incorporating a specified amount of Nb into a dead soft steel sheet contg. a specified amount or below of Ti basing on the total amount of C and N.
CONSTITUTION: The composition of a dead soft steel is composed of, by weight, ≤0.01% C, ≤0.01% N, ≤0.15% Si, ≤0.6% Mn, ≤0.1% Al, ≥4×(C+N)% Ti, 1/ 6×TiW31/4×C% Nb and the balance Fe with inevitable impurities. The amounts of C, N, Si and Mn are restricted as mentioned above so as to ensure press workability, and Al is added by only an amount necessary for deoxidation.
