P20 Mold Steel Forging Overview
AISI P20 is a low-alloy plastic mold steel commonly supplied in a pre-hardened condition. It provides a practical combination of machinability, toughness, polishability and dimensional stability for mold and tooling applications.
The pre-hardened delivery condition can reduce or eliminate additional hardening after rough machining. P20 is commonly used for injection molds, blow molds, extrusion dies, mold bases, mold holders and other medium-duty tooling components.
We supply custom P20 mold steel forgings in the form of blocks, flat bars, round bars, mold blanks and other drawing-based components. Production requirements are reviewed according to dimensions, unit weight, machining allowance, delivery hardness, surface requirements, testing scope and documentation requirements.

Applications of P20 Mold Steel Forgings
P20 mold steel forgings are commonly selected for molds and tooling components requiring machinability, toughness, polishability and uniform pre-hardened performance.
Injection Molds
Mold cavities, cores, inserts and tooling components for medium- and large-size plastic injection molds.
Blow Mold Tooling
Mold blocks, cavities and tooling components used for plastic blow-molding applications.
Extrusion Dies
Extrusion dies and related tooling requiring good machinability, dimensional stability and consistent hardness.
Mold Bases and Holders
Mold bases, mold frames, holders and structural tooling components manufactured according to customer drawings.
