Zusammenfassung:	Embodiments of the present disclosure are directed to coiled steel tubes and methods of manufacturing coiled steel tubes. In some embodiments, the final microstructures of the coiled steel tubes across all base metal regions, weld joints, and heat affected zones can be homogeneous. Further, the final microstructure of the coiled steel tube can be a mixture of tempered martensite and bainite. Des modes de réalisation de la présente divulgation concernent des tubes en acier enroulés et des procédés de fabrication de tubes en acier enroulés. Dans certains modes de réalisation, les microstructures finales des tubes en acier enroulés à travers toutes les régions métalliques de base, les joints de soudure et les zones affectées par la chaleur peuvent être homogènes. En outre, la microstructure finale du tube en acier enroulé peut être un mélange de martensite revenue et de bainite.
