X40Cr14 Steel: A Guide to 1.2083 / AISI 420C Properties and Applications 

X40Cr14, also known by its designations DIN 1.2083 and AISI 420C, is a premium martensitic stainless tool steel engineered for applications that demand high hardness, exceptional polishability, and reliable corrosion resistance. Its formulation, which includes approximately 13% chromium, provides a robust combination of wear resistance and resilience against oxidation. This makes it a preferred material for manufacturing plastic molds, precision surgical instruments, and cutting tools where both performance and surface integrity are critical. 

As a leading supplier of specialized alloys, Nifty Alloys LLC stocks and distributes certified X40Cr14 stainless steel in various forms, including round bars, plates, and custom-forged blocks. We ensure that engineers, mold makers, and industrial buyers receive materials that meet stringent international standards, ready for demanding applications. 

What is X40Cr14 Stainless Steel? 

X40Cr14 is a high-carbon martensitic stainless steel, formally classified under the DIN 1.2083 standard. It is specifically designed for tooling applications where a combination of hardness, wear resistance, and good corrosion resistance is essential. The material is notable for its ability to achieve a high-quality, mirror-like polish, a critical feature for plastic mold manufacturing. Its excellent dimensional stability following heat treatment ensures that intricate components maintain their precise shapes during service. 

You will find X40Cr14 steel is frequently selected for manufacturing plastic injection molds, particularly for processing corrosive polymers like PVC. Its properties also make it ideal for producing cutting tools, food processing equipment, and medical devices that require sterilization and a clean surface finish. The grade offers a balanced set of attributes that cater to precision engineering challenges.
