P5 is a high-carbon high-chromium tool steel produced by Carpenter Technology Corporation. P5 steel grade is similar to AISI’s D5 steel grade. P5 steel is a low-alloy steel that was designed to be easy to machine.

P5 steel is classified as a general-purpose, through hardening tool steel. It has good resistance to wear and a high level of toughness, making it a popular choice for cutting tools, including drills, taps and reamers.

The chemical composition of P5 steel is:

* Carbon: 1.50%

* Chromium: 12.00%

* Vanadium: 0.80%

* Molybdenum: 1.00%

* Silicon: 0.30%

* Manganese: 0.40%

* Sulphur: 0.030% max.

* Phosphorus: 0.030% max.

The combination of these elements gives P5 steel its distinctive properties, such as its high wear resistance and toughness.
