Abstract

PURPOSE: To provide a corrosion-resistant ferritic stainless steel excellent in resistant to high-temperature cracking at the time of welding, toughness at weld zone and corrosion resistance by specifying the respective contents of Cr, Mo, Mn, Nb, C, N, Si, P, S and (C+N) and the ratio of Nb to (C+N).
CONSTITUTION: This stainless steel contains, by weight, 20.0W25.0% of Cr, 0.3W 1.5% of Mo, 0.2W0.5% of Mn, 0.1W0.6% of Nb, up to 0.03% of C, up to 0.7% of Si, up to 0.03% of P and up to 0.01% of S, wherein (C+N)≤0.04%, and Nb≥ 12(C+N), the balance being Fe. The stainless steel contains the expensive alloying element Mo in a smaller amount, and has properties comparable or superior to those of 18Cr-2Mo-Nb steels. In addition, unlike the case of 18Cr-2Mo-Nb steels, the corrosion resistance of this steel is not significantly affected by S or dissolved-Nb content, and the steel can be easily produced with high reliability.
