Stainless Steel 420 is a high-carbon martensitic stainless steel that contains about 12–14% chromium and low carbon content, allowing it to be heat treated for impressive hardness. Mechanically, it boasts excellent tensile and yield strength, good wear resistance, and moderate corrosion resistance. This alloy achieves high hardness after heat treatment while still maintaining enough toughness for tough applications. Its unique combination of strength, durability, and corrosion resistance makes Stainless Steel 420 hollow bars perfect for components that face mechanical stress, wear, and moderately corrosive environments, ensuring long-term reliability in both industrial and precision applications.

SS 420 hollow bars' excellent wear resistance enhances their performance by ensuring durability in high-friction environments. This property makes them ideal for cutting tools, medical instruments, and mechanical components, reducing maintenance needs and extending service life in demanding applications.
SS 420 hollow bars offer moderate high-temperature resistance but are generally not ideal for prolonged exposure to extreme heat. Their performance is best in applications requiring hardness and corrosion resistance under controlled or moderately elevated temperature conditions.
Stainless Steel 420 hollow bars find extensive use in the manufacturing of knives, cutting tools, valve components, and precision machinery parts that require high hardness and wear resistance. They are also utilized in automotive, aerospace, and industrial applications where dimensional stability and moderate corrosion resistance are crucial. The material’s ability to maintain mechanical integrity under stress and resist wear makes it an excellent choice for shafts, fasteners, and components that undergo repetitive use. Stainless Steel 420 hollow bars provide engineers with a dependable solution for long-lasting, high-performance components.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
