1.2738 Tool Steel (P20+Ni)

1.2738 Plastic Mould Steel: Nickel-Enriched for Large-Scale Precision. Superior through-hardenability for massive injection moulds and dies.

1.2738 Tool Steel (P20+Ni)

1.2738 is an advanced version of P20 (1.2311), modified with a 1% Nickel addition. This modification ensures that the hardness remains consistent from the surface to the very core of large blocks, preventing "soft spots" during the machining of deep cavities.

Chemical Composition	Percentage %
Carbon	0.40%
Manganese	1.50%
Nickel	1.00%
Chromium	1.90%
Molybdenum	0.20%

For measuring and cutting tool steels, the recommended pre-treatment process typically involves spheroidizing annealing to improve machinability and prepare the material for subsequent hardening. The final heat treatment generally consists of precision quenching followed by low-temperature tempering, enabling the steel to achieve a hardness range of 60–65 HRC. Critical heat treatment parameters such as hardening temperature, heating and cooling rates, and soaking duration must be carefully adjusted according to the component’s shape, dimensions, and composition. Additional factors, including furnace design, quenching medium selection, and material transfer systems, also contribute significantly to the final performance and consistency of the steel.

Certified Quality Assurance

At Progressive Metal Manufacturing, we back our materials with a commitment to international excellence. Our 1.2738 tool steel is sourced and distributed under a strict ISO 9001 quality management system. This ensures that every plate delivered meets the highest metallurgical standards for purity and performance. For manufacturers, this means complete traceability and a guarantee of material consistency, which is essential for maintaining the integrity of large-scale production tools.
