Inox Steel India is a trusted manufacturer, supplier, stockist, and exporter of Forged Square Bars, supplying heavy-duty open die forged square bars for applications where internal soundness, grain refinement, and high mechanical strength are critical. Forged square bars are widely used in power plants, oil & gas, heavy engineering, forging houses, defence, and large OEM manufacturing, where rolled bars may not meet performance requirements.
Unlike hot rolled or bright bars, forged square bars are produced by compressive deformation of heated steel billets, which results in directional grain flow, superior impact resistance, and enhanced fatigue strength. This makes forged square bars the preferred choice for high-load, high-stress, and safety-critical components.
All forged square bars supplied by Inox Steel India are manufactured in accordance with ASTM, EN, and IS standards, ensuring reliable metallurgy, traceability, and compatibility with project specifications.
A forged square bar is a solid square-section bar produced through open die forging, where heated steel is shaped under repeated compressive force. This process improves the internal structure of the metal compared to rolling.
Key characteristics of forged square bars include:
Forged square bars are commonly selected where strength, reliability, and long service life are more important than surface finish.
Inox Steel India follows controlled forging practices to ensure consistent quality.
Manufacturing Process Overview:
This process produces high-integrity square bars suitable for extreme service conditions.
Forged square bars offer performance advantages not achievable with rolled products:
These advantages make forged square bars ideal for heavy engineering and safety-critical industries.
Inox Steel India supplies forged square bars in multiple material categories:
🔹 Carbon Steel Forged Square Bars
Used for general heavy engineering, shafts, and structural components.
🔹 Alloy Steel Forged Square Bars
Used for high-stress components requiring enhanced strength and toughness.
🔹 Stainless Steel Forged Square Bars
Used where corrosion resistance and mechanical strength are both required.

Standard Forged Square Bar Sizes (mm)
25 | 30 | 35 | 40 | 45 | 50 | 60 | 65 | 70 | 75 | 80 | 100 | 120 | 150 | 200 | 250 | 300 | 400 | 600
Length: As required / Cut lengths
Tolerance: Forging tolerance (machining allowance recommended)
Finish: As forged / Rough machined
Forged square bars are generally supplied oversize to allow finish machining.
Forged square bars are heavier due to solid cross-section and large size, typically supplied based on per piece or per kg weight.
Weight Calculation Formula:
Weight (kg) = Side (mm) × Side (mm) × Length (m) × 7.85
Weight varies slightly based on forging allowance and heat treatment condition.
Forged square bar pricing depends on material grade, size, heat treatment, and machining requirement.
