The bainitic steel casting process is relatively complex compared to martensitic alloy steel. Ensuring quality stability and uniformity, especially in the quenching and tempering process, is the current focus of research and production control. Due to the lower content of alloying elements, the comprehensive cost is moderate. GESION's air-cooled bainitic steel, after normalizing and tempering heat treatment, exhibits a microstructure composed of austenite, bainite, and ferrite. It possesses excellent ductility, high hardness, and strength, overcoming the typical disadvantages of low comprehensive mechanical properties, especially low impact toughness, in bainitic steels. GESION's quenched and tempered bainitic steel is well-suited for wear-resistant applications in mining equipment, featuring high hardness, excellent wear resistance, and good plasticity and toughness coordination, making it one of the main products developed in recent years.
