P20 tool steel properties

P20 Tool Steel Description

P20 tool steel (1.2311) is a fantastic grade offering excellent machinability. P20 is a universally applicable vacuum chrome-molybdenum steel, requiring no further heat treatment. Sheffield Gauge Plate is capable of supplying different forms of P20, and even though it is provided with no additional heat treatment needed, P20 is still ready for machining due to its increased ‘S’ content. It’s a tough, pre-tempered steel with high core strength.


Alternatively, Sheffield Gauge Plate can supply P20S tool steel (1.2312) which contains a higher sulphur content, allowing for more outstanding machinability than its P20 counterpart. However, if you plan to have a polished or refined finish, P20S would not be suitable.


P20N tool steel (1.2738) is prehardened on delivery and contains extra nickel for greater hardness in large sections, an easy to polish surface and superb machinability.


If you plan to anneal you should heat uniformly to 770-790°C, before soaking and cooling in the furnace.


Delivery condition: tempered approx. 1050N / mm²
