DIN 1.2083 (X40Cr14) Steel is a high-performance martensitic stainless steel that belongs to the Cr series of German plastic mold steels. It is widely used in the plastic molding industry due to its excellent properties. With 13% chromium content, it provides exceptional wear resistance, excellent acid resistance, superior polishing ability, and good workability.
This steel is particularly well-suited for molds requiring good polishing and corrosion resistance, especially in acidic plastics. After quenching, it exhibits enhanced wear resistance, making it ideal for electro-erosion operations and molds that require high surface finish quality.
DIN 1.2083 is typically smelted using ESR (Electro-Slag Remelting) technology, ensuring high purity and quality. The steel is usually delivered in an annealed condition, allowing for easy further processing and heat treatment to meet specific application requirements. This makes DIN 1.2083 an excellent choice for durable, high-precision plastic mold production.
