Hongxin - Model DIN 1.2083 -Stainless Plastic Mold Steel for Tooling Applications
DIN 1.2083 is a martensitic stainless steel widely used in plastic mold manufacturing and other tooling applications. It offers high corrosion resistance, excellent polishability, and superior wear resistance, making it suitable for precision components like injection molds and extrusion dies. The steel grade can be identified as 1.2083, X40Cr14, SUS420J2, or 4Cr13. It is characterized by good polishability and resistance to both corrosion and hot oxidation. The heat treatment process includes annealing at 750-800°C followed by furnace cooling, stress relieving after machining and before final heat treatment, hardening with preheating to 600-700°C, and austenitizing at 990-1040°C. The steel is then quenched and tempered, typically achieving a hardness of HRC 52-56. The material is available in various forms such as rounds with diameters from 12-500mm and plates/blocks with thicknesses from 8-300mm and widths from 210-710mm. Testing includes tensile strength, yield strength, elongation, hardness, and ultrasonic inspection. Delivery terms are flexible, offering various international trade options.1.2083 is a type of stainless steel that is commonly used in the manufacturing of plastic molds and other tooling applications.
