Abstract

According to the present status of research and development of high strength non-quenched and tempered cold heading steel at home and abroad

the chemical composition

characteristics of process

structure and mechanical properties of 800 ~ 1200 MPa high strength non-quenched and tempered cold heading steels are analyzed and discussed. The high strength non-quenched and tempered cold heading steel should has high strength and excellent cold-forming property

of which the strength and hardness of hot rolled products should be controlled in a suitable range. The steel grade can get better structure and mechanical properties by using low carbon high manganese and micro-alloying steel series with thermal-mechanical control rolling process.
