Low-alloyed steel grades for boilers in ultra-supercritical power plants

Autor: F. Masuyama

To achieve energy conservation and environment protection, it is essential to increase steam temperature and pressure of fossil-fired power plants as ultra-supercritical conditions, and it is required to use high-strength, high-performance materials

Temperature and stress dependence of creep life of welded joints in strength enhanced high Cr ferritic steels

Autor: K. Maruyama, F. Masuyama, Y. Hasegawa, H. Morimoto, Kyosuke Yoshimi

Publikováno v: Energy Materials. 4:70-75

Overestimation of creep life is a serious problem that happens in long term creep of welded joints made of 9–12%Cr ferritic steels. Creep rupture data of welded joints made of grades 91, 92 and 122 steels were subjected to multiregion analyses payi

Japanese experience with steam oxidation of advanced heat-resistant steel tubes in power boilers

Autor: N. Nishimura, Y. Hirayama, F. Masuyama, N. Komai

Publikováno v: Materials at High Temperatures. 22:3-10

Japanese experience of steam oxidation behavior of advanced heat-resistant steel tubes in power boilers is discussed. Severe scale separation, cracking, and exfoliation were observed in T91 pendant reheater tubing in a Japanese utility boiler after a

T23 and T24 – new generation low alloyed steels

Autor: A. Shibli, F. Masuyama, Sanjooram Paddea

The new low-chromium steel grades T/P23 and T/P24 are candidate materials for components of ultra-supercritical power plants, and as potential replacement materials of conventional low alloy ferritic steels such as T/P22 in older plants. Higher creep

Effect of Ce addition on the sensitization properties of stainless steels

Autor: Vivekanand Kain, T. Tonozuka, F. Masuyama, Tetsuo Shoji, T. Kondo, Yutaka Watanabe

Publikováno v: Scripta Materialia. 42:307-312

Rare earth elements are characterized by significant negative free energy changes for compound formations, such as carbides, sulfides and oxides. It has been reported that the effect of the addition of cerium to the steels, on their corrosion propert
