- Stainless Steel 304 Round Bar
Neeka Tubes stocks SS 304 round bar in a wide range of sizes for buyers who need dependable stainless steel raw material. We work as a 304 Stainless Steel round bar manufacturer and also supply hexagonal, square and flat sections for structural and mechanical applications. SS 304 Round Bar is an austenitic stainless steel, also called SS 1.4301 Round Bar, with good mechanical strength and solid corrosion resistance in most industrial settings. We supply it to ASTM A276 and ASTM A479 specifications, so buyers get a traceable product with proper documentation.
Stainless Steel 304 round bars have 18 to 20% chromium and 8 to 10.5% nickel, which is what gives them the corrosion resistance they’re known for. Tensile strength is 75,000 psi, yield strength sits at 30,000 psi, enough for load-bearing parts without adding unnecessary weight. Manganese stays under 2%, carbon is capped at 0.08%, so it machines without much trouble on standard shop equipment. Elongation of 35% means it bends and forms without cracking. ASTM A479 SS 304 round bar is used across structural, industrial and mechanical work, and it holds up over a long service life.
Features of Stainless Steel 304 Round Bar
- Higher Machinability – Its smooth surface and easy workability allow efficient machining, cutting, and production in the industry.
- Superior Weldability – SS 304 can be welded using standard techniques, ensuring strong and durable fittings without compromising structural integrity.
- Durable – This round bar maintains its strength over time, reducing maintenance costs and increasing the lifespan of various applications.
- Available Sizes – This bar is available in sizes ranging from 4 mm to 101.6 mm, making it suitable for different industrial and engineering applications.
- Surface Finish – Smooth and polished finish enhances visual appeal, making it ideal for decorative and architectural applications.
- Non-Magnetic in Nature – SS 304 is non-magnetic, making it useful for electrical and specialized applications that require minimal magnetic interference.
SS 304 Round Bar is applied for construction, automotive, food processing as well as marine industries. It is suitable for shafts, fasteners and structural parts.
