What is industrial 1.2083 steel plate used for in precision manufacturing?

Industrial 1.2083 steel plate is a martensitic stainless steel, known for its high hardness, excellent corrosion resistance, and superior polishability, and it is primarily used in precision manufacturing for producing molds, dies, and tooling components that require a mirror-like surface finish and high wear resistance. Specifically, it is the go-to material for plastic injection molds, especially for processing corrosive plastics like PVC, ABS, and polycarbonates, where the steel’s chromium content (around 13%) prevents pitting and degradation. In precision manufacturing, industrial 1.2083 steel plate is also used for cutting tools, medical device components, and food processing equipment, where hygiene and dimensional stability are non-negotiable. The steel is typically supplied in a hardened and tempered condition, achieving a hardness of 48-52 HRC (Rockwell C scale), which allows it to withstand high clamping forces and repeated thermal cycles without deformation. Data from tool steel suppliers shows that 1.2083 plates have a tensile strength of 1,800-2,000 MPa and a yield strength of 1,400-1,600 MPa, making them suitable for high-stress applications. In practice, manufacturers often use this steel for optical lens molds, because its machinability after annealing (around 200 HB) allows for intricate geometries, and its ability to be polished to a surface roughness of Ra 0.01 µm ensures flawless light transmission.
