The Power of Precision: Unveiling DIN 1.2738 Steel and AISI P20+Ni Tool Steel

DIN 1.2738, often referred to as AISI P20+Ni (or P20 Mod), is a pre-hardened plastic mould steel that has gained immense popularity worldwide due to its excellent machinability, high polishability, and good through-hardening properties.

The addition of nickel (Ni) significantly enhances its hardenability, allowing for uniform hardness throughout larger sections, which is crucial for big moulds.

This robust material is engineered to deliver superior performance in the demanding environment of plastic injection moulding.

Key Properties of DIN 1.2738 / AISI P20+Ni Tool Steel:

Pre-Hardened Condition: Supplied in a pre-hardened state (typically 280-325 HB or 28-34 HRC), eliminating the need for further heat treatment by the end-user for many applications. This saves time and reduces distortion risks.
Excellent Machinability: Despite its pre-hardened state, DIN 1.2738 offers very good machinability, allowing for efficient and precise machining of complex mould cavities and features.
High Polishability: Crucial for plastic moulding, this steel can achieve a very high surface finish, which directly translates to excellent surface quality on the moulded plastic parts.
Good Through-Hardening (with Ni addition): The nickel content ensures uniform hardness distribution even in larger cross-sections, preventing soft spots and enhancing the mould’s overall integrity and performance.
Good Toughness: Offers a good balance of hardness and toughness, providing resistance to chipping and cracking under operational stresses.
Homogeneous Microstructure: Known for its clean and uniform microstructure, which contributes to consistent performance, predictable machining behavior, and superior polishability.
Sufficient Strength and Wear Resistance: While not a high-wear resistance tool steel like D2, it provides adequate strength and wear resistance for typical plastic moulding applications, especially for unreinforced plastics.
Ease of EDM (Electrical Discharge Machining): Shows good performance during EDM processes, which are often used for creating intricate details in mould cavities.

Common Applications of DIN 1.2738 / AISI P20+Ni Tool Steel:

The unique combination of properties makes DIN 1.2738 / AISI P20+Ni a preferred choice across a multitude of industries, primarily in the manufacturing of plastic injection moulds:

Plastic Moulds Making Industry: This is the primary and most significant application. It’s ideal for medium to large-sized plastic injection moulds for automotive parts, consumer goods, electronic housings, and other components requiring good surface finish and dimensional accuracy.
Automotive Industry: Extensively used for moulds that produce various automotive interior and exterior plastic components, such as dashboards, bumpers, door panels, and trim.
Consumer Goods: Moulds for appliances, household items, toys, and packaging.
Electronic Housings: For manufacturing precision plastic enclosures for electronic devices.
Pressure Die Casting: While less common than hot work steels like 1.2344, 1.2738 can be used for certain components in pressure die casting dies, particularly for non-ferrous alloys with lower melting points, or for support bolsters.
Rubber Moulds: Used for moulds that produce rubber components due to its good machinability and polishability.
Hydroforming Tools: For certain hydroforming applications where moderate pressure and good surface finish are required.
Industrial Machines and Parts Making: Components requiring good strength and machinability in a pre-hardened state.
Industrial and Defense Industry Parts Making: For certain structural or component parts where ease of machining and good mechanical properties are required, without the need for extreme wear resistance.
Sheet Metal Cutting: While not a primary application, it can be used for certain bolster plates or support structures in stamping dies due to its good strength.
Forging Industry: Primarily for bolster plates or support structures in forging dies, rather than the working dies themselves.

Deep Dive into DIN 1.2738 / AISI P20+Ni: Composition, Equivalents, and Alternatives

To make the most informed material selection, a thorough understanding of DIN 1.2738’s metallurgical characteristics, its equivalent grades, and potential alternatives is crucial.

Chemical Composition of DIN 1.2738 (Approximate Weight %):

The precise chemical composition is fundamental to the steel’s performance characteristics, particularly its through-hardening capability and machinability. While slight variations may occur between manufacturers, the typical composition of DIN 1.2738 is as follows:

Carbon (C): 0.35 – 0.45% (Contributes to hardness and strength.)
Silicon (Si): 0.20 – 0.50% (Deoxidizer; improves strength and elasticity.)
Manganese (Mn): 0.60 – 1.00% (Improves hardenability and hot workability.)
Chromium (Cr): 1.80 – 2.10% (Contributes to hardenability, temper resistance, and some wear resistance.)
Molybdenum (Mo): 0.20 – 0.40% (Enhances hardenability, improves temper resistance, and contributes to overall strength.)
Nickel (Ni): 0.90 – 1.20% (Crucially improves through-hardening capability, especially in large sections, and enhances toughness.)
Sulfur (S): Max 0.030% (Kept low to minimize brittleness.)
Phosphorus (P): Max 0.030% (Kept low to minimize brittleness.)

Equivalent Grades to DIN 1.2738 / AISI P20+Ni:

Recognizing equivalent grades is essential for international specifications, global sourcing, and understanding cross-referenced material properties.

AISI P20+Ni (USA): This is the most widely recognized and functionally identical equivalent, sharing virtually the same chemical composition and performance characteristics, particularly its improved through-hardening due to nickel.
JIS NAK55 (Japan): While not a direct identical equivalent in composition, NAK55 is a pre-hardened mould steel with similar applications (often with better machinability and polishability due to specific alloying) that can be considered an alternative for similar purposes. It’s often nickel-aluminum alloyed.
X40CrMoNi5-11-2 (EN / W. Nr. 1.2738): This is the European standard designation for the same steel. The “Ni” in the name explicitly points to the nickel content.
GB 3Cr2NiMo (China): The Chinese equivalent, also mirroring the properties of P20+Ni.
ASSAB 718 (Sweden): A well-known commercial brand name for a steel very similar to 1.2738.

Alternative Grades to DIN 1.2738 / AISI P20+Ni:

While DIN 1.2738 excels in plastic moulding, certain applications might benefit from alternative grades offering slightly different property profiles.

DIN 1.2311 (40CrMnMo7 / AISI P20): This is the standard P20 grade without the nickel addition. It has similar properties but lower through-hardenability, making it less suitable for very large mould sections where uniform core hardness is critical. It’s generally more economical and widely used for smaller to medium-sized moulds.
DIN 1.2312 (40CrMnMoS8-6 / AISI P20+S): This is a P20 grade with added sulfur for improved machinability. While it machines faster, the sulfur inclusions can negatively impact polishability and mechanical properties (toughness) in some instances. Good for applications where machinability is paramount and polishability is less critical.
DIN 1.2085 (X33CrS16 / AISI 420F Modified): A pre-hardened stainless mould steel. If corrosion resistance (e.g., for processing PVC or other corrosive plastics, or for moulds operating in humid environments) is a primary concern, 1.2085 might be an alternative. However, its machinability and polishability might differ, and it is typically more expensive.
DIN 1.2344 (X40CrMoV5-1 / AISI H13): A hot work tool steel. While 1.2738 is a cold work/plastic mould steel, for moulds subjected to very high temperatures (e.g., in high-temperature engineering plastics or for certain die casting applications), 1.2344 might be considered due to its excellent hot strength and thermal fatigue resistance. It is not typically supplied pre-hardened to mould hardness.
DIN 1.2379 (X153CrMoV12 / AISI D2): A high-carbon, high-chromium cold work steel known for extreme wear resistance. If the plastic being moulded is highly abrasive (e.g., heavily glass-filled), D2 might be considered for higher wear resistance, but its machinability and polishability characteristics are different, and it’s not supplied pre-hardened.

Choosing the right alternative depends heavily on the specific demands of the mould or tool, including size, required surface finish, type of plastic being processed, operational temperature, desired service life, and cost considerations. Our experienced team at Milano Special Steel can provide expert guidance in selecting the most suitable grade for your unique needs.
