With a commitment to providing top-notch materials, Garg Steels ensures that every 440C hollow bar is meticulously crafted to meet stringent specifications across a variety of industries. These hollow bars find extensive use in machining, tooling, and bearing applications, where both corrosion resistance and mechanical strength are crucial. Garg Steels prides itself on delivering consistent quality, prompt delivery, and tailored solutions for clients in diverse industrial sectors.
Stainless Steel 440C Hollow Bar is a high-carbon martensitic stainless steel that contains around 16–18% chromium, 0.95–1.2% carbon, along with trace amounts of manganese and molybdenum. It boasts impressive tensile strength (up to 760 MPa) and hardness (up to 58 HRC when heat treated). While it offers moderate resistance to corrosion, its standout features are its remarkable hardness, wear resistance, and edge retention. The hollow design helps reduce weight while preserving high strength, making it perfect for precision components and parts that face significant stress and abrasion.

Stainless Steel 440C Hollow Bars are perfect for applications that require high levels of hardness, strength, and wear resistance. They are commonly used in bearing races, valve components, cutting tools, surgical instruments, and dies, particularly where precision is key. In sectors like aerospace, automotive, medical, and defense, these hollow bars are integral to components that withstand intense mechanical stress. Their machinability in the annealed state and ability to achieve a high polish make them ideal for instrumentation and high-precision engineering. Although they are not as corrosion-resistant as austenitic grades, 440C performs reliably in mildly corrosive environments when properly hardened and finished.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
