DIN 1.2316 plastic mold steel has 17% chromium element, its corrosion resistance and polishing performance are great, pre-hardening hardness is 34 – 40 HRC. 23616 steel material has great mechanical properties, so it is widely used in the plastic mould industry.

1.2316 plastic mould tool steel, supplied from stock in rounds, flats and plate.

1.2316 is a chrome-molybdenum steel with improved corrosion resistance properties, 1.2316 possesses good polishability, toughness, heat resistance and wear-resistant properties. It is often used for tools for processing chemically aggressive plastic materials (e.g. PVC).

1.2316 is a martensitic stainless chromium steel with uniform hardness in all dimensions, it is easy to machine, high surface finish and polishability. 1.2316 is commonly used for plastic moulds, and offers a higher corrosion resistance than 1.2083. It can be used with for the manufacturing of chemically aggressive materials like PVC and plastics containing abrasive fillers.

We can deliver 1.2316 in the pre hardened condition (300HB or 340HB).

This grade is not suitable for nitriding and chrome plating because of the high chrome content.

Typical applications:

Injection mould for plastics, die-casting moulds, moulding of corrosive material (PVC), extrusion tools.
