Stainless Steel 304 Round Bar

304 Stainless Steel Round Bar

ASTM A276 type 304 stainless steel square bar and SS 304 hex bar supplier in Mumbai

304 Stainless Steel Round Bar is measured across the diameter. It is a long cylindrical metal bar stock that has many commercial and industrial applications. It is the most common stainless steel round bar. As the main non-iron constituents it contains both chromium and nickel metals. It is an austenitic stainless steel which is less electrically and thermally conductive than carbon steel and is essentially-magnetic but less magnetic than steel.
astm a276 grade 304 is a material grade specification for cold finished or hot finished bars in stainless steel 304, it is available in forms of rounds, hexagon, square and other  hot rolled extruded shapes. astm a276 type 304 condition in which bar are annealed. astm a276 type 304 conditions in which bars are strain hardened or relatively light cold worked.

304 stainless steel rods are solid bar with circular cross section. It is manufactured are hot or cold rolling and drawing. The processing methods are cutting, heat treating and machining. It is used for a number of applications such as gear, shafts, bearing, pumps, food processing equipment, fittings, valves, mining machinery etc. It also come in billet form and generally includes a cross-section based on the shape of rod or bar stock. It provides excellent resistance to a wide range of atmospheric environments and many corrosive media. In warm chloride environment it is subject to pitting and crevice corrosion and to stress corrosion cracking above about 60 °C.

ss 304 flat bar are typically used for engineering, mining infrastructure, transport and storage, residential, etc. It does not require any special pre-heating or welding. It is provides excellent corrosion and rust resistance. 304 stainless steels are the most versatile and due to its corrosion resistance it is widely used austenitic stainless steel in the world.

ss 304 hex bar are long, hex shaped bar It has a smooth surface finish is machinable and provides excellent mechanical properties and it is easy to weld, form, cut and machine. 

ss 304 square bar common applications include gates and protective barriers of window and ornamental work. It is easy to shape, easy to weld, cut, form and machine with the proper knowledge and equipment.For more severe corrosion conditions, it is commonly replaced by stainless steel 316, when stainless steel 304 is too sensitive to pitting or crevice corrosion by chlorides or general corrosion in acidic applications.
