Technical Review UDC 669 . 14 . 018 . 292 - Nippon Steel

development of the continuous casting process made it possible to apply TMCP even to heavy-gauge steel plates. For example, TMCP was employed to develop penstock steel HT100 (TS 950 MPa class) having a thickness of 100 mm. The progress of the abovementioned steelmaking process technology has led to the development of ad- Technical Report UDC 691 . 71 - Nippon Steel Corporation process (TMCP) steel yield strength (YS) 325 N/mm2, YS 355 N/ mm2) for plates in the thickness range of up to 100 mm was devel-oped for building structures by applying TMCP; they have been used since the latter half of the 1980s subject to acquisition of rec-ognition of the Minister of Construction at the time.

Recent Development in Microstructural Control Technologies development and technology of large thickness tmcp steel

Recent Development in Microstructural Control Technologies through the Thermo-Mechanical Control Process (TMCP) with JFE Steels High-Performance Plates erties of welds performed by customers3,4). Needless to say, the TMCP technology with Super-OLAC is essential to JFE EWEL. In 2004, JFE Steel started operation of an epoch- Optimization of mechanical properties of low carbon bainitic development and technology of large thickness tmcp steel employed to product high strength steel plates in many large steel mills. Recently, Nishioka and Ichikawa (2012) systematically reviewed the history of TMCP development, including metallurgical development and technology of large thickness tmcp steel A Novel thermo-mechanical controlled processing for large development and technology of large thickness tmcp steel A novel TMCP involving UFC was used to produce microalloyed 560 MPa (X80) pipeline strip (with critical thickness of 22 mm) at a pilot-plant scale by adopting high temperature coiling process. Re-reddening phenomenon of large-thickness pipeline strip was considered during controlling of coiling temperature.

Through-Thickness Properties of TMCP Steels | Journal of development and technology of large thickness tmcp steel

The results of through-thickness tensile tests showed that this TMCP steel has good through-thickness ductility in spite of the presence of high sulfur segregation at the centerline. However, the results of slow strain tests on a hydrogen charged through-thickness tensile specimen showed some deterioration in ductility. Thermo-Mechanical Control Process: Part One :: Total Materia development and technology of large thickness tmcp steel Todays steel plates are produced not by the ordinary rolling method, but by TMCP technology, which incorporates micro-structural control suitable for higher strength and thickness, together with advanced micro-alloying technology. The application of TMCP for bridge steel started around 1996 when the HPS (High-Performance Steel) began to be development and technology of large thickness tmcp steel The significance of softened HAZs in high strength development and technology of large thickness tmcp steel - TWI Komizo, Y 'Performance of welded joints in TMCP steel plates'.
