Inox Steel India is a reliable manufacturer, supplier, stockist, and exporter of stainless steel square bars in India, offering premium-quality square bars in SS 304, 304L, 316, 316L, 310, and 321 for domestic and international engineering industries.
Our stainless steel square bars are supplied to OEM manufacturers, fabrication units, machining workshops, infrastructure projects, and industrial plants across India, GCC countries, Africa, Europe, and the Americas.
Stainless steel square bars are widely used where strength, dimensional accuracy, corrosion resistance, and machining precision are critical.
Compared to round bars and flat bars, square bars provide better edge definition, higher torsional stability, and uniform load distribution, making them ideal for structural frameworks, CNC-machined components, shafts, couplings, and fabricated assemblies.
All square bars supplied by Inox Steel India are manufactured in compliance with ASTM A276 / ASTM A479 standards, ensuring consistent metallurgical properties, superior surface finish, and long-term performance in demanding service conditions.
A stainless steel square bar is a solid long product with a square cross-section, produced from austenitic stainless steel grades and supplied in hot rolled, bright drawn, forged, or polished form.
These bars are designed to deliver excellent mechanical strength, corrosion resistance, and fabrication flexibility across a wide range of industrial applications.
Stainless steel square bars are preferred in industries where components are exposed to:
Because of their uniform geometry, square bars are especially suitable for precision machining and fabrication, offering clean edges and predictable material behavior during cutting, drilling, and welding operations.
At Inox Steel India, stainless steel square bars are produced using controlled manufacturing and finishing processes to meet strict dimensional and quality requirements.
This process results in square bars with excellent straightness, consistent dimensions, and superior machinability.
SS 304 / 304L Square Bars: Used for general engineering, fabrication, food processing, and architectural applications. 304L is preferred for welded fabrication.
SS 316 / 316L Square Bars: Molybdenum-bearing grade offering superior resistance to chlorides and chemicals. Ideal for marine and pharmaceutical equipment.
SS 310 Square Bars: Designed for high-temperature and oxidation-resistant applications such as furnaces.
SS 321 Square Bars: Titanium-stabilized grade suitable for high-temperature service where weld stability is required.
