Common Steels Used in Injection Mold - ALTA Special Steel

Other Considerations for Tool Steel When Making Critical Choices. Pre-hardened steels are used for the low production tools. Many times the mold plate is P-20 steel and the molding can be cut solid into the plates. Areas of the plate could be inserted with hard steel if needed for shut offs or wear surfaces. High Hardness Steel P20 HRC 40 Extraordinary Products High Hardness Steel P-20 HRC 40 is the Versatile, Low-Alloy Steel. To put it another way, Steel P20 HRC 40 Contains a Variety of Carbon and its Alloy. It has Good Toughness at Common Strength Levels. This high hardness steel p20 is best for making of tools.

How To Choose Material For Injection Molds, S7, P20, NAK

P20 is the old standard pre-hard steel, and it is still quite popular. It does have a tendency to work harden and contain hard spots, but, with carbide tooling so commonly used, this is not much of an issue. Mold steel - P20 or not P20? - Canadian MetalworkingApr 25, 2013 · The other is that P20 can be commonly machined in the pre-hardened and tempered condition, then readily treated post-machining if necessary. The use of pre-hardened grades, however, adds pressure on the mold maker. Deep cavities require thick section blocks which, if poorly heat-treated, will have a pronounced case and core effect.

UDDEHOLM TOOL STEELS FOR PLASTIC MOULDING

UDDEHOLM PREHARDENED MOULD AND HOLDER STEEL Uddeholm Impax Supreme (AISI P20 modified), which is refined by the vacuum degassing technique, offers good machinability and homogeneity, excellent polishability and consistent photo-etching properties due to a low sulphur content. What You Should Consider When Purchasing Modified P20 Paul W. Britton, International Mold Steel, Inc. P20, a 4130, 4135 modified material, has long been the steel of choice for pre-hardened mold steels. P20 is classified as a chrome-moly alloy, with a carbon content of approximately 0.30 to 0.40. Over time, many variations on basic P20 chemistry have been introduced to the marketplace. 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 operating costs.
