When sourcing high-quality stainless steel materials, professionals across industries rely on 420 stainless steel plate for its exceptional durability and corrosion resistance. Our 3Cr13 stainless steel is specifically engineered to meet rigorous standards, making it a top choice for applications requiring reliability. The cold rolled stainless steel process enhances the material's strength and surface finish, ensuring superior performance in demanding environments. For those seeking a premium finish, our 2B finish stainless steel offers a smooth, reflective surface that is easy to clean and maintain. Additionally, the matt stainless steel plate variant provides a non-reflective, aesthetic appeal ideal for architectural and decorative uses. Each product, including the stainless steel plate 420, is manufactured to exact specifications, guaranteeing consistency and quality for your projects.


The 420 3Cr13 Cold Rolled 2B Matt Stainless Steel Plate is a martensitic stainless steel grade known for its high carbon content, which contributes to excellent hardness and wear resistance. This plate undergoes a cold rolling process that refines its grain structure, resulting in improved mechanical properties and a uniform thickness. The 2B finish provides a cold-rolled, annealed, and pickled surface with a smooth, slightly reflective appearance, while the matt finish option delivers a dull, non-glare surface suitable for applications where aesthetics and minimal light reflection are important. With a typical chemical composition including carbon, chromium, and other elements, this plate offers good corrosion resistance in mild environments and is often used in cutlery, surgical instruments, and industrial components. Its combination of strength, formability, and surface quality makes it a versatile choice for various technical and decorative purposes.
