Abstract: Research status of non-quenched and tempered cold heading steels for fasteners in China was summarized. The strengthening and toughening mechanisms were discussed from the aspects such as grain refinement and dislocation strengthening. In addition, the key to control the microstructure and performance of cold heading steel rolled materials and deep processing fasteners was clarified. Finally, the development trend and research focus of non-quenched and tempered cold heading steels were summarized, aiming to provide a theoretical basis for the development and production of 10.9 grade high-strength non-quenched and tempered cold heading steels.

Key words: bainitic non-quenched and tempered cold heading steel, research status, strength and toughness mechanism, microstructure and performance regulation
