1: DIN 1.2316 steel introduction
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.
This grade is not suitable for nitriding and chrome plating because of the high chrome content.

6:HEAT TREATMENT
already pre-toughened; usually no heat treatment required
Soft annealing:
760 to 800 °C for about 4 to 5 hours; slow controlled cooling of 10 to 20 °C per hour to about 650 °C; further cooling in air, max. 230 HB
Hardening:
1030 to 1050 °C
15 to 30 minutes keeping curing temperature
quenching in water/oil
obtainable hardness: 49 HRC
Tempering:
Slow heating to tempering temperature immediately after hardening. Minimum time in furnace: 1 hour per 20 mm part thickness
7: Delivery condition
For hot forged or hot rolled bar, usually the delivery condition is hot forged or rolled, annealed, rough turned.
For hot forged plate, usually the delivery condition is hot forged, annealed, milled surface.
For hot rolled plate, usually the delivery condition is hot rolled, annealed, black surface.
