AB Steel is a trusted manufacturer, supplier, and exporter of alloy steel round bars from our base in Mumbai. We supply to industries across India and to clients worldwide, delivering bars that combine strength, precision, and reliability. Our customers count on us for products that perform under pressure, last for years, and meet strict international quality standards.

Alloy steel is different from ordinary carbon steel because it has extra elements such as chromium, nickel, molybdenum, and vanadium added to it. These additions make the steel stronger, more resistant to wear, and capable of working in extreme temperatures without losing its shape or toughness. At AB Steel, we select high-grade raw materials and apply controlled heat treatments so that each round bar meets both mechanical and dimensional requirements.

We manufacture our alloy steel round bars in accordance with ASTM A182, ASTM A276, ASTM A479, ASTM A322, ASME SA182, and ASME SA479. Diameters range from 10 mm to 500 mm, with lengths reaching up to 6 meters. If your project needs something outside the standard range, we can cut and finish bars to your exact specifications.

Our production covers popular grades like AISI 4130, 4140, 4340, and 8620, as well as other specialized engineering alloys. These grades are often chosen for making high-strength components such as gears, shafts, axles, crankshafts, drill collars, and pressure-resistant fittings.

The finish of a bar can make a big difference depending on the application. We can supply polished bars for a smooth and bright appearance, black finish bars for heavy industrial use, or precision-ground bars where exact size and surface quality are critical. Every bar is inspected before it leaves our facility to ensure it meets the agreed specifications in size, straightness, and mechanical properties.

Industries around the world trust our alloy steel round bars because they perform in harsh and demanding environments. In oil and gas, they are used in drilling and production equipment. Automotive and transport industries use them in rotating parts that endure constant stress. In construction, they serve in structures where high load-bearing strength is essential.

From Mumbai, we ship our alloy steel round bars across India and export to markets around the globe. Our customers choose AB Steel because they know they will get consistent quality, on-time delivery, and a product that is ready to go straight into service without rework.
