After quenching and tempering, 40Cr alloy steel plate and Corten A plate sheet have good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel Corten A plate is good. It can be hardened to Ф28 ~ 60mm during water quenching and Ф15 ~ 40mm during oil quenching. In addition to quenching and tempering, this steel is also suitable for cyanidation and induction hardening. The cutting performance is better. When the hardness is HB174 ~ 229, the relative cutting workability is 60%. 40Cr alloy steel is suitable for making medium-sized plastic molds.
The user of S355NC grade must make sure that his calculation, design and processing methods are appropriate for the Corten A plate material. The forming process used must be suitable for the intended application and comply with the state-ofthe- art; it is of fundamental importance to the processing behaviour of this Corten A plate steel grade.
