Advanced High-Strength Hot Coils
Hot rolled duplex steel is an advanced high-strength steel composed of ferrite and martensite. It has a low yield ratio and a high initial work hardening rate. Besides,there is a good balance between strength and ductility. It also has good welding and anti-fatigue performance, etc. Therefore, these characteristics solve the problem of difficult stamping of high-strength low-alloy steel. And make duplex steel suitable for manufacturing complex shaped parts, such as car wheels and other components
High Hole Expansion Steel
High hole-expansion steel is an important kind of AHSS. It not only has high strength and good elongation, but also has good formability and flange ability. These qualities can meet the forming requirement of auto parts with complex shapes, such as the lower arm. It can also be applied to other parts with flanging. Besides,its flange ability is expressed by hole-expansion ratio.
