Inox Steel India is a reliable manufacturer, supplier, and exporter of Alloy Steel Round Bars in high-strength grades AISI 4140, AISI 4340, EN19, and EN24, manufactured and supplied as per ASTM A29 / A322 and EN 10083-3 standards.
Our alloy steel round bars are widely used in heavy engineering, automotive, power transmission, oil & gas, forging, and machinery manufacturing, where high tensile strength, toughness, and fatigue resistance are critical.
With ready stock in hot rolled, forged, and bright drawn conditions, Inox Steel India supports both OEM production requirements and large-scale project supplies, delivering material with full traceability and consistent metallurgical quality.
Alloy steel round bars are solid cylindrical bars produced by adding alloying elements such as chromium, molybdenum, and nickel to carbon steel. These elements significantly enhance strength, hardness, wear resistance, and impact performance, making alloy steel round bars suitable for demanding mechanical applications.
At Inox Steel India, alloy steel round bars are manufactured using controlled processes to achieve uniform microstructure and reliable mechanical properties.
This controlled manufacturing ensures alloy steel round bars suitable for high-load, high-stress, and cyclic service conditions.
These advantages make alloy steel round bars a preferred choice for critical mechanical and structural components.
