摘要
Abstract
Partial corrosion of one SUPER304H steel tube of boiler for ultra-supercritical electric power unit occurred in coastal areas.The macroshape, chemical composition, metallography and microscopic area of corrosion are analyzed. It is found out that it is Cl-caused pitting corrosion. Countermeasures is put forward accordingly, which brings out a practics accumulation for futuremaintainment.关键词
