The Super 304H steel has a structure characteristic of austenitic steels with visible annealing twins and single primary NbX precipitates. Long-term ageing in steel leads to numerous precipitation processes of M23C6, MX carbides, s phase, Z phase, and e-Cu pha...
发明人: 原子 茂也 摘要: PROBLEM TO BE SOLVED: To provide a composite film for deep drawing which is free from a problem of irregular draw at sealing and shows good molding properties and proper rigidity and is suitably used for packaging with a reclosable-type gas pack.收藏...

304HStainless steelWeldCreepStress relaxation crackingCircumferential cracking was found in 304H stainless steel welds between the nozzle and end-plate of a Stylene Monomer (SM) reactor serviced at 560 degrees C. The cracks had been repaired, but they repeatedly reappeared after two years of ...
MICROSTRUCTUREHARDNESSSTEELThis study presents the results of microstructure and hardness tests of a homogenous welded joint made of Super 304H stainless steel after 1000 h of ageing at the temperature of 700 and 750掳C. Super 304H steel is commonly used for high-pressure...

Steam oxidation of a Super 304H boiler tube was performed at steam temperatures of 650掳C and 700掳C for time durations up to 5000h. The oxidation scale outcomes which formed on as-received untreated and shot-peened (SP) tubes were studied using X-ray diffraction (XRD), scanning electron ...
For the aged Super 304H, the GB's M23C6 provided a higher cracking source. In addition, the nano Cu-rich particle restricted the twin-induced plastic deformation of austenitic grain and depressed the absorbed energy from austenitic grain deformation....
