Zusammenfassung:PURPOSE:To give excellent creep rupture strength at high temp. required to for atomic reactor, etc., by limiting composition of ferrite steel and making it tempered martensite structure containing delta-ferrite phase or tempered martensite single phase structure by heat-treatment. CONSTITUTION:The ferrite steel is composed of by wt% of 0.02-0.15% C,
