420 Stainless Steel Plate

420 stainless steel plate is known for its elevated carbon content, distinguishing it from grades 410 and 416. Like type 410, it offers good machinability in the annealed condition. Often categorized as surgical steel, 420 stainless steel is a versatile material suited for high-performance applications. At HByeson, we provide customized 420 stainless steel plates in a variety of sizes, types, and shapes tailored to your requirements.

Wide Range of Applications

Thanks to its favorable chemical properties, 420 stainless steel plate is ideal for uses that demand a balance of corrosion resistance and high hardness. Common applications include pump shafts, plastic molds and dies, cams, firearms, pivots, steel balls, fasteners, and tapes. It is also well-suited for medical and surgical instruments such as scissors, knife blades, cutlery, needle valves, lens molds, gauges, shear blades, hand tools, and ball check valves.

Features of 420 Stainless Steel Plate

420 stainless steel plate offers a combination of high strength, hardness, and toughness. It resists corrosion in environments such as freshwater, air, food products, gasoline, and mild acids. Additional advantages include good ductility and superior polishability, making it a reliable choice for precision components and finished products.
