1.1206 Ck50

.

 

This grade yields a high surface hardness, combined with relatively good toughness. This grade also has good forging characteristics. It is shallow hardening, however, and useful section size is limited. Parts made from grade 1.1206 steel requiring strength is oil quenched; parts requiring high hardness is water quenched.
