20CrMnTi(H) hot rolled H‑hardenability alloy steel round bar
20CrMnTi(H) is a high-quality alloy carburizing gear steel under GB standard. It features excellent deep hardening ability, high strength, and good wear resistance after carburizing and quenching. The steel maintains fine grain structure even at high carburizing temperatures, making it ideal for automotive gears, transmission shafts, and other precision mechanical parts requiring high toughness and surface hardness.
