P20 mold steel
P20 mold steel Detailed introduction
Factory hardness HRC30~42, suitable for large and medium-sized precision molds, suitable for long-term production of high-quality plastic molds, for large mold frames. This steel has good machinability and can be generally polished.
Chemical composition of P20 steel: P20 steel is mainly composed of carbon (C), silicon (Si), manganese (Mn), chromium (Cr) and molybdenum (Mo) and other elements. Its chemical composition is: carbon 0.28-0.40%, Silicon 0.20-0.80%, manganese 0.60-1.00%, chromium 1.40-2.00%, molybdenum 0.30-0.55%.
P20 mold steel characteristics
1. Hardness of P20 steel: P20 steel has a high hardness, generally between 30-35 HRC (Rockwell hardness). This hardness makes P20 steel suitable for the manufacture of various plastic molds, able to withstand high pressure and wear.
2. Processing performance of P20 steel: P20 steel has good processing performance, can be cut, grinding, polishing and other processing technology. It has good cutting performance and can meet the needs of manufacturing molds.
3. Toughness of P20 steel: P20 steel has good toughness and can resist external forces such as impact and extrusion. This toughness enables P20 steel to withstand large loads and stresses in plastic mold manufacturing.
4. Heat treatment of P20 steel: The common heat treatment method of P20 steel is quenching and tempering. Quenching can improve the hardness and wear resistance of P20 steel, and tempering can improve its toughness and machinability.
Matters Needing Attention And Application Of P20 Mold Steel
P20 steel is widely used in plastic injection mold, die casting mold, extrusion mold and other fields
It can produce high-precision, wear-resistant, corrosion-resistant molds, suitable for the production of various plastic products.
P20 steel requires proper maintenance and maintenance during use.
