Stainless Steel 420 Hollow Bar is a martensitic stainless steel that contains about 12–14% chromium and has a carbon content of around 0.15–0.40%. This composition allows for effective hardening through heat treatment. It boasts high tensile strength, good yield strength, and excellent wear resistance after processes like quenching and tempering. The alloy also offers moderate corrosion resistance in mildly corrosive environments and is easy to polish. Its mechanical properties include enhanced hardness, improved fatigue resistance, and dimensional stability, making it ideal for precision-machined hollow components that need to withstand demanding service conditions and repeated mechanical loading in industrial applications and tooling.

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 applications that require high strength, wear resistance, and the ability to be internally bored. Common applications include pump shafts, valve components, bushings, sleeves, and precision mechanical parts. These bars are frequently utilized in the automotive, aerospace, oil and gas, power generation, and tooling industries. The hollow design not only reduces material weight but also maintains structural integrity, enhancing machining efficiency and cost-effectiveness. Thanks to their heat treatability and durability, they are a go-to choice for many industrial applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
