The material 12hn3a is an alloyed chrome-nickel steel intended for the production of components that require good strength, ductility, and toughness of the core as well as good surface hardness and are used under impact stress or at sub-zero temperatures.

The material 12hn3a combines excellent strength with good ductility and very good impact toughness at low temperatures.

Steels of this grade are among the best structural steel grades. The combination of nickel and chrome gives this steel the properties required for the manufacture of critical parts.

Since nickel is completely dissolved in solid solution, it increases the hardness and strength of ferrite significantly more than chrome. The simultaneous presence of nickel and chrome in the steel results in a good combination of mechanical properties and high hardenability.

Nickel has a favorable effect on hardenability and gives the core good toughness with a slight increase in strength. It lowers the temperatures required for heating the surface layer and core during quenching and helps keep the steel fine-grained during normal hardening. Nickel contributes to the good toughness of hardened case-hardened steels used at low temperatures.

Properties of 12hn3a:

• excellent hardenability
• excellent plastic deformability
• high impact toughness at low temperatures
• excellent strength

Main application areas for the material 12hn3a:

• Construction
• Worm gears
• Gears and shafts
• Elastomer couplings
• Piston pins
