SS Black Round Bars are solid cylindrical stainless steel products that offer superior strength, corrosion resistance, and excellent machinability.
Industries widely use these bars in engineering, construction, manufacturing, and heavy industrial applications where durability and performance are critical.
At Hastgiri Industries Pvt. Ltd., we manufacture and supply premium-quality SS Black Round Bars in multiple grades including 304, 304L, 303, 310, 316, 316L, 410, 420, and 431, ensuring compliance with international quality standards and industry-specific requirements.
SS Black Round Bars are stainless steel bars produced through hot rolling or forging processes, resulting in a dark or black surface finish.
Unlike polished or bright bars, black bars retain their mill-scale finish, making them ideal for structural and heavy-duty applications where surface aesthetics are secondary to strength and performance.
These bars offer excellent mechanical properties, corrosion resistance, and high load-bearing capacity, making them suitable for demanding environments.
