Ferritic stainless steel with improved strength, workability, and corrosion resistance

Abstract

Disclosed is a ferritic stainless steel with improved strength, workability, and corrosion resistance, which may be applied to various industrial fields, such as washing machines, refrigerators, and all kinds of electric home appliances. An embodiment of the disclosed ferritic stainless steel comprises, in percent by weight (wt %), 0.0005 to 0.02% of C, 0.005 to 0.02% of N, 0.7 to 1.0% of Si, 16.0 to 17.0% of Cr, 0.05 to 0.3% of Ti, and the balance being Fe and inevitable impurities, wherein the ferritic stainless steel has a value of Formula (1) below satisfying 21 to 25, a tensile strength of 470 MPa or more, and an elongation of 27% or more. 7*Si+Cr  (1) In Formula (1), Si and Cr represent the contents (wt %) of the respective elements.
