The material 12hn3a is an alloyed chrome-nickel steel intended for the production of components requiring good strength, ductility, and core toughness, as well as good surface hardness and used under impact stress or at subzero temperatures.
The material 12hn3a combines excellent strength with good ductility and very good notch impact toughness at low temperatures.
Steels of this grade are among the best structural steels. The combination of nickel and chrome gives this steel the properties required for the production of critical parts.
Since nickel is completely dissolved in solid solution, it significantly increases the hardness and strength of the ferrite more than chrome. The simultaneous presence of nickel and chrome in the steel provides a good combination of mechanical properties and high hardenability.
Nickel positively influences hardenability and provides the core with good toughness with a slight increase in strength. It lowers the temperatures required for heating the surface layer and core during quenching and helps to keep the steel fine-grained during normal hardening. Nickel contributes to the good toughness of hardened case-hardened steels used at low temperatures.
