DIN 1.2085 steel is a corrosion-resistant, pre-hardened plastic mold steel with excellent wear resistance. It is commonly used for injection molds and tooling applications where high hardness and corrosion resistance are required. Below are its key characteristics of the DIN 1.2085 steel: Chemical Composition of the DIN 1.2085 steel :- Element Percentage (%) Carbon (C) 0.33 – 0.45 Silicon (Si) ≤ 1.00 Manganese (Mn) ≤ 1.00 Chromium (Cr) 12.50 – 14.50 Molybdenum (Mo) 0.20 – 0.50 Sulfur (S) 0.05 – 0.15 Properties of the DIN 1.2085 steel : • Hardness: Typically supplied in the pre-hardened condition (~ 32-38 HRC) • Corrosion Resistance: Higher compared to standard plastic mold steels due to its chromium content. • Wear Resistance: Good wear resistance for extended mold life. • Machinability: Improved due to added sulfur. • Polishability: Suitable for high surface finish requirements. • Toughness: Moderate, suitable for plastic molding applications. Applications of DIN 1.2085 steel :- • Injection and compression molds for corrosive plastics. • Parts exposed to humid or corrosive environments. • Components requiring good polishability and high wear resistance. • Medical and food industry molds due to its corrosion resistance.
