Features

1. Chemical compositions and characteristics

Advantages

(1) Adding minor amounts of boron increases hardenability. These alloy-saving structural steels can reduce resource risk and cost.
(2) High hardenability enables deep hardening by induction quenching and ensuring the strength of the product.
(3) Compared with alloy steels with equivalent hardenabilty, the hardness after rolling or normalizing etc. becomes lower, which can improve the cold forgeability and machinability.

Major applications

Automotive/Truck: CVJ intermediate shafts, rear shafts, etc.
