Stainless Steel 304 Hollow Bars are a go-to choice for many applications that need a blend of corrosion resistance, durability, and lighter weight. As a top-notch austenitic stainless steel grade, SS 304 shines in formability and weldability, making these hollow bars perfect for machining, fabrication, and structural uses. Their hollow design not only cuts down on material usage but also keeps strength intact, which is crucial for components where reducing weight matters. With a sleek finish, uniform dimensions, and dependable mechanical performance, SS 304 hollow bars are trusted across various industries for their consistent and long-lasting functionality.
These hollow bars are made up of about 18% chromium and 8% nickel, giving them outstanding resistance to corrosion, oxidation, and chemical exposure. They boast a tensile strength ranging from 515 to 620 MPa and a yield strength of around 205 MPa, ensuring reliable stability under mechanical stress. SS 304 also maintains excellent ductility, toughness, and ease of machining, even in colder conditions. Its non-magnetic property when annealed, along with a solid strength-to-weight ratio, makes these hollow bars suitable for both precision tasks and heavy-duty applications.
