Abstract
PURPOSE: To obtain high strength without deteriorating the hot workability and corrosion resistance of SUS304 by utilizing the dissolving action of Si and N in addition to N of stainless steel, further adding an adequate amount of Mn, and adjusting the Cr and Ni contents.
CONSTITUTION: This steel consists of, by wt., ≤0.08% C, 1.2W3.0% Si, 2.3W 5.5% Mn, 7W15% Ni, 16W22% Cr, 0.20W0.40% N and the balance Fe with impurities. N is most important to strengthen the matrix and is effective in forming a structure with remarkably increased pitting corrosion resistance, yet above the upper limit of N deteriorates the hot workability, etc. Si dissolves in the matrix to strengthen it and improves the corrosion resistance, etc. The lower limit of Si is decided from the viewpoint of hot workability, etc., and the upper limit from the viewpoint of a reduction in the N dissolving limit and the structural balance. The upper limit of Cr is decided from the viewpoint of the structural balance, and that of Ni from the viewpoint of hot workability and a reduction in the N dissolving limit. Mn raises the N dissolving limit according to the Si, Cr and Ni contents, yet above the upper limit of Mn deteriorates the hot workability.
