• This case hardening steel has applications in all mechanical assemblies working at temperatures above 150°C e.g. gears, fuel injectors. It is also used for parts requiring a good adherent PVD layer.
This steel can be gas pressure quenched, which reduces distortion caused by heat treatment.
• Case hardening and through hardening steel with excellent hardenability, high mechanical properties and a surface hardness of around 700 HV after carburizing at tempering temperatures of up to 350°C.
• The good temper resistance of this steel allows it to be used with a duplex treatment (carburizing + quenching + nitriding) to obtain a good case depth and surface hardness of more than 800 HV.
