Hollow Bar

Stainless steel hollow bars are metal tubes with a cylindrical shape featuring a central void. The material used in manufacturing these bars is stainless steel, a corrosion and rust-resistant type of steel. These bars come in a variety of sizes, shapes, and thicknesses, offering versatility that makes them ideal for various applications across industries like aerospace, construction, marine, and automotive. They are commonly used in producing shafts, hydraulic cylinders, structural components, conveyors, and pressure vessels. A protective layer of chromium oxide forms on the surface of the metal due to the presence of at least 10.5% chromium in the stainless steel used to produce these hollow bars.
