P3Cr2Mo 1.2311 P20 steel mechanical properties
The mechanical properties mainly include tensile strength, yield strength, elongation, area or reduction, hardness, impact value, non-metalic inclusion etc. Different heat treatment, the mechanical properties will be different, such as normalized, tempered, QT. If you want to know the properties, kindly contact the sales.

Hardening
Harden from a temperature of 830-880oC followed by oil or air quenching or warm bath quenching 180-220oC. Hardness after quenching is 51 HRC.

Tempering
Tempering temperature: See the data bellow.

Forging
Hot forming temperature: 1050-850oC.

Machinability
Machinability is relatively good at about 80% that of the W group water hardening steels

Corrosion Resistance
This is a steel alloy and it will corrode or rust unless protected.

 P3Cr2Mo 1.2311 P20 Delivery condition
For hot forged plate, usually the delivery condition is hot forged, annealed/QT, milled surface
For hot rolled plate, usually the delivery condition is hot rolled, annealed/QT, black surface.
