standard. Moreover, the modied T23 steel exhibits an enhanced reheat-cracking susceptibility compared with T23 steel. Under tensile load at high temperature, it is not easy for the micro-voids and micro-cracks to form at the grain boundaries, which is related to the carbides and M/A constituents in the modied T23 steel. 14:40:15:00(1221900)

CONTRIBUTION TO RESEARCH OF WELDABILITY OF engineering units. In the 1990´s Japan developed a steel called T23, which is based on CrMoVWNbN alloying, and subsequently steel F-2W with CrMoVWTiN alloying. At the same time, a steel called T24 was developed in Germany (CrMoVTiN alloying). T23 and T24 steels are used at 500 to 600°C. Their chemical composition was
Effect of long-term aging on the microstructure and Feb 01, 2018 · Steel T23 was developed on the basis of steel T/P22 (10CrMo9-10) to enhance creep rupture strength by substituting W for a portion of Mo and adding the elements V, Nb, and N. After proper normalizing and tempering (NT) or quenching and tempering (QT) treatment, T23 exhibits a stable fully bainitic microstructure with creep rupture strength
The extrusion process is used to manufacture high-alloy steel tubes, such as stainless steel, and special tubes, such as finned tubes. The push bench process is suited for manufac-turing large-diameter, thick-wall tubes, and enables the manufacturing of carbon steel, alloy steel, and stainless steel

Abstract:T23 is modern bainitic steel designed for use in supercritical boilers. According to producers data weldability of this steel is good enough to avoid post-weld heat treatment. However, some of the T23 weld joints in as-welded condition have not met the minimal ductility requirement.
