Wheel is made up of the rim and the disk. The main processing technique for rim is roll forming. Punch forming and spin forming are usually applied for disc. Punch forming is mainly used for disc of passenger cars, while disc of commercial cars are usually punch-formed (wigh inner tire) or spin-formed (without inner tire)

BR290/440HE has high strength, good elongation, food formability and flangeability, which can meet the forming requirement of auto parts with complex shapes, such as lower arm, etc. It can also be applied to other parts that need flanging. The flangeability is expressed by the hole expansion ratio. Hole expansion ratio is one of criteria to the formability of steels. It reflects the material’s resistance to local cracking because of large local stretch in the direction perpendicular to the hole during hole expansion.
