Description
PRE=%Cr+3.3×%Mo+16×%N (1)
PREN=%Cr+3.3×(%Mo+0.5%W)+30×%N (2)
ただし、項(%Mo+0.5%W)は0.8<(%Mo+0.5%W)<4.4の範囲に制限される。この米国特許出願の鋼の目的は、式(2)で算出されるPRENを35より大きくして高い耐食性を得ることである。米国特許出願第2004/0050463号の鋼は、たとえば2205の二相ステンレス鋼より良好な耐食性を有するが、これらの鋼は、熱間加工性の改善のために高いマンガン、ニッケルおよびタングステン含量を有している。これらの合金化成分、とくにニッケルおよびタングステンにより、鋼は、たとえば2205の二相ステンレス鋼より高価になる。
