For molds with extremely low requirements, S50C and 45# steels may be used, i.e. creating a cavity directly in the mold base The spec. of plastic injection mold steel. 1.USA standard:AISI. Code:P1-P19Low Carbon Steel. P20-P39Low Carbon, High SAE-AISI P2 (T51602) Low-Carbon Mould Steel ::SAE-AISI P2 (T51602) Low-Carbon Mould Steel. SAE-AISI P2 steel is a tool steel. P2 is the designation in both the SAE and AISI systems for this material. T51602 is the UNS number. It can have the lowest tensile strength among the tool steels in the database. The properties of SAE-AISI P2 steel include two common variations.
Apr 01, 2004 · Alternative materials, particularly a range of steels such as P-20, H13 tool steel and stainless steels as well as copper-based alloys often containing beryllium, have been used in tool and mold applications. They offer high strength and wear resistance, and, in the case of the copper alloys, thermal conductivity. TOOLING:How to Select the Right Tool Steel for Mold Aug 25, 2016 · With cavity steel or alloy selection there are many variables that can dictate the best option. Things that need to be considered are the material youll be molding, cycle-time expectations, part criteria, expected volume, tooling costs, and maintenance. What You Should Consider When Purchasing Modified P20 Nov 01, 2004 · 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.
