JIS G3461 Tabung baja karbon terutama digunakan untuk menukar panas di bagian dalam dan di luar tabung, seperti tabung air, tabung asap, tabung superherater, tabung preheater udara, dll. Dari boiler, dan industri penukar panas. Ini tidak berlaku untuk tabung baja untuk pemanasan tungku dan yang untuk penukar panas untuk layanan suhu rendah.
