May 17, 2021 · This paper reports the degradation assessment of Super304H during the creep by using misorientation-derived parameters (EBSD). The results manifested that with increasing creep time, the change of misorientation parameters (i.e., Kernel Average Misorientation [KAM], grain reference orientation deviation [GROD], Grain Orientation Spread [GOS], and geometrically necessary Diffusion Kinetics of Chromium in a Novel Super304H Feb 01, 2017 · Diffusion behavior and diffusion kinetics of chromium (Cr) from the pure chromium coating in the matrix of Super304H and TP304H steels were investigated in a temperature range of 600-900 by using energy-dispersive spectrum (EDS) quantitative line scanning and Fick's second law of diffusion. Pure Cr coating was obtained by electroplating. Experimental results show that the diffusion depth

Investigation on High Temperature Corrosion Characteristic Sep 24, 2020 · The high temperature corrosion characteristic of Super304H, TP347H, and HR3C steel in an ultrasupercritical coalfired boiler with service time of 17,973 h was investigated. The samples were analyzed by XRD, SEM, and EDS. Ordering of Primary Carbonitrides in an Austenitic Steel Super304H austenitic steel, which is based on 18Cr-8Ni stainless steel and alloyed with about 3 wt.% Cu and a small amount of Nb (<1 wt.%) and N (<0.2 wt.%), is widely used in ultra-super critical (USC) power plants due to its excellent high-temperature performance, especially

Stainless Steel 304H Compression Fittings is also Structure and properties of Super 304H steel for pressure Purpose:Material condition assessment with regard to required utility properties of Super304H austenitic steel for operation at elevated temperature. Design/methodology/approach:The structural and mechanical testing at room and elevated temperature after annealing at 650°C and 700°C for 1000 and 3000 h was carried out. Findings:The effect of temperature and duration of long-term annealing
Exposed to 650°C air, TP304H stainless steel with two different grain size was oxidized at this temperature. At the meantime, comparison of their oxidation was through the oxidation kinetics curves and analysis of the morphology and composition of oxide scale which conducted by SEM and X-ray. The results showed that the oxidation rate of TP304H stainless steel was slowed down by grain SUPER304H UNS S30432 USC Boiler Tube - India - Trading Recently, a new type of austenitic stainless steels called Super304H stainless steel, containing 3% copper is being adopted for super critical boiler applications. The SCC behavior of this Super 304H stainless steel has not been widely reported in the literature. Many researchers have studied the SCC behavior of steels as per various standards.
