1. What is 1.2316 Steel?

DIN 1.2316 material is a chrome-molybdenum tool steel known for its improved corrosion resistance properties. This steel variant boasts excellent polishability, toughness, heat resistance, and wear-resistant properties. It is widely favored for tools designed to process chemically aggressive plastic materials, such as PVC. The steel material 1.2316 is martensitic stainless chromium steel, offering uniform hardness across all dimensions. It’s easy to machine and provides a high surface finish and polishability. 1.2316 is often chosen over steel 1.2083 due to its superior corrosion resistance which makes it ideal for manufacturing chemically aggressive materials like PVC and plastics containing abrasive fillers.
