hard mould steel
P-20 High Hard is a pre-hardened mold steel that has been specially designed for large plastic molds. Material is forged on a 5000 ton press assuring maximum deformation during the forging process. Supplied hardness of 321352 HB (34-38 HRC). Hardness loss in large cross sections is minimal. High Speed Steel Tool Steel P20 Mold Steel P20P20 Mold Steel P20 Mold Steel is a versatile, low-alloy tool steel that is characterized by good toughness at moderate strength levels. The steel is commonly used for plastic injection mold cavities and tooling and for die casting dies for zinc. P20 is typically sold in the pre-hardened condition at a hardness of approximately 300 HBW.
Mar 27, 2021 · Halogen-containing plastic material such as polyvinyl chloride (PVC) and polyacetal often releases corrosive gases to damage the mould. The best way is to use corrosion resistant steel, such as S136H, PAK90, etc. In addition, beryllium copper is also a good corrosion resistant steel material. NAK55 STEEL - Titus SteelNAK55 is a precipitation, or age-hardened mold steel with a through hardness of approximately 40 HRc. NAK55 is ideal for use in plastic and rubber molds and other applications where impact resistance is not critical. It is a super clean, Vacuum-Arc Remelted steel with uniform grain structure, uniform hardness and excellent dimensional stability. P20 High Hard Steel Plate,High Hard Plastic Mould Steel P20 high hard steel plate is low alloy steel & also has chrome-moly in it. This tool steel is equivalent to Corrosion Resistance steel & h13 hot die steel. It has a carbon content between 0.35 to 0.40 approximately. There are many new variations of basic p20 high hard steel plate are
The tool steel 1.2767 offers high toughness and is used for adequately stressed moulds. Moreover this steel offers a good polishability, ability for photo etching and eroding. What is the difference between 718H mold steel and P20H Aug 20, 2020 · 2.P20H die steel is made of pure steel through vacuum degassing refining treatment, which is more suitable for polishing or Etching on plastic mold. 3.The P20H mold steel has been pre-hardened to 285-330HB(30-36HRC). which can be directly used for mold processing without heat treatment, greatly shortening the construction period and saving its High Hard Plastic Mould Steel - DIN 1.2738 Steel Plastic High Hard Plastic Mould Steel P20 Steel type of a Stainless steel it will be used for very high quality surface finish need to produce Clear lenses and clear automotive parts. which are normally supplying in Pre hardened condition. the Hardness in as supplied condition 275
