Effects of Heat Treatment and Composition Modification on SAE 8620 Steels

Abstract:

Article Preview

The effects of quench-tempering treatment and composition modification on SAE 8620 steels have been investigated. Experimental results show that the 400°C tempering of SAE 8620 steels can exhibit an excellent overall performance, including the mechanical strength, impact toughness and corrosion resistance. By slightly adding alloy elements into SAE 8620 steels, the modified HSLA steels exhibit excellent hardenability, high mechanical strength and elongation, and ductile fracture behavior. These excellent performances are comparable to those of HSLA-100 steels and can satisfy well the requirement of Grade 100 lifting components.
