During the ASME Pressure Vessels & Piping Conference (PVP) held in San Antonio (USA) from 15 to 19 July, the paper entitled “Consideration on Tempering and PWHT Temperatures of C-Mn and Low Alloy Steels for the Fabrication of Pressure Vessels: Smart Tuning of Heat Treatment Parameters” was awarded Best Paper of ASME PVP2018 (Prague) for the “Material and Fabrication (M&F)” track. This 2018 paper was co-authored by Sylvain Pillot (ArcelorMittal Global R&D), Mikihiro Sakata (JGC), Valéry Ngomo and Lionel Coudreuse (ArcelorMittal Industeel).
Realised in collaboration with Japanese Engineering Company JGC, the paper aims at strengthening the technical position of both Industeel and JGC on heat treatments of pressure vessels grades. It was awarded by ASME among the 150 papers of the M&F track and was recognised as an outstanding technical paper. Sylvain Pillot, as the lead author, received the Certificate of Honour from Pierre Mertiny (Chair, 2018 PVP Conference) and Clay D. Rodery (Chair, PVPD Honors & Awards).
This reviewed paper serves as a technical basis during discussions with customers and to ask for derogations on heat treatment parameters (temperature and/or duration) to be performed on plates.
The secondary objective of the paper is to explain the effects of heat treatment during pressure vessel steel production on the actual properties of various steel grades.
Ultimately, a recommendation on heat treatment parameters is proposed and submitted to the consideration of end-users, fabricators and engineering companies.
