Ｓｕｐｅｒ3 0 4Ｈ钢是一种新型 1 8 8奥氏体不锈钢 ,它主要用于制造超超临界锅炉的过热器和再热器。日本住友和三菱重工在ＴＰ3 0 4Ｈ钢的基础上联合开发了Ｓｕｐｅｒ3 0 4Ｈ钢。该钢制成的锅炉管已在ＷａｋａｙａｍａＫｙｏｄｏ电力公司的实机锅炉上 (参数 :1 9ＭＰａ ,5 71
Super3 0 4H steel is a new 1880 austenitic stainless steel that is primarily used to manufacture superheaters and reheaters for ultra-supercritical boilers. Sumitomo and Mitsubishi Heavy Industries in the TP3 0 4H steel based on the joint development of Super3 0 4H steel. The boiler tube made of this steel has been placed on a real boiler in Wakayama Kyodo Power Company (parameters: 19 MPa, 5 71
