What is 1.2316 ESR Mould Steel?

Link: 1-2316-esr-mould-steel

Product Description

1.2316 ESR Mould Steel is a premium stainless plastic mould steel manufactured through the Electro Slag Remelting (ESR) process, which produces a cleaner and more uniform steel structure with enhanced mechanical properties. This advanced refining process improves toughness, wear resistance, corrosion resistance, and polishing performance, making the material ideal for precision mould manufacturing.

The steel contains carefully balanced amounts of chromium and molybdenum, providing excellent protection against corrosion while maintaining high hardness and thermal stability. Alloying elements such as nickel, manganese, and silicon further improve strength, machinability, and dimensional stability, allowing the material to perform reliably under demanding production conditions.

With its excellent mirror-polishing capability and resistance to chemically aggressive plastics, DIN 1.2316 ESR Mould Steel is widely selected for premium plastic moulds that require exceptional surface quality and extended service life. Compared with conventional mould steels, it offers improved corrosion resistance, lower maintenance requirements, and greater durability.

Its combination of high toughness, superior wear resistance, and excellent machining characteristics makes it suitable for injection moulding, extrusion tooling, precision mould manufacturing, and other industrial applications where long-term performance is essential.
