Custom P20 Steel Mold Tooling

Pre-Hardened General Purpose Mold Steel

P20 steel is the most commonly used material for molds in the plastics manufacturing industry because of its unique characteristics and excellent machinability. Some of its main properties include:

  • Hardness
  • Good polishing ability
  • Heat treatment possible after machining
  • Good corrosion resistance 
  • Good wear and tear resistance
  • Good thermal stability

P20 steel is an easy material to work with and a great choice for large production runs of 50,000+ parts. This versatile, low alloy tool steel provides good toughness at a reasonable price tag. Typical applications include:

  • Plastic Injection Molds
  • Rubber Compression Molds
  • Prototype Molds
  • Zinc Die Casting Dies
  • Holder Blocks
  • Transfer Molds

A variety of hardness levels are attainable for P20 steel through additional heat treatments. Versatility and a balance of properties give it an extremely wide range of applications in the automotive industry and beyond. On account of its properties, P20 steel can be used in a variety of molding processes, including:
