Our ISO 9001:2015 certified facility in Mumbai produces ASTM, ASME, and EN compliant round bars for clients in oil & gas, petrochemical, power generation, and aerospace sectors across North America, Europe, Middle East, and Asia-Pacific. With in-house testing capabilities including PMI, tensile testing, and hardness verification, we ensure every round bar meets specified tolerances and material certifications.
Round bars are solid cylindrical metal rods manufactured from stainless steel, mild steel, and specialized alloys for precision engineering, construction, and industrial applications. Stellar Alloys Steel Pipes and Tubes manufactures ASTM A276-certified stainless steel round bars, mild steel round bars, and alloy steel rounds with superior tensile strength, corrosion resistance, and machinability for demanding environments including marine, chemical processing, and high-temperature operations.
At Stellar Alloys Steel Pipes and Tubes, we supply different types of round bar rod products including stainless steel round bars, mild steel round bar, aluminium round bar, and alloy steel round bars. These bars are known for their excellent strength, corrosion resistance, durability, and machinability. Industries rely on steel rounds and stainless round bar materials because they perform well in harsh environments such as marine, chemical processing, and high-temperature applications.
With over 15 years of manufacturing expertise and ISO 9001:2015 certification, we supply round bars to automotive, aerospace, oil & gas, and construction industries across 40+ countries. Our state-of-the-art production facility processes 5,000+ tons of round bar stock monthly with +/- 0.02mm dimensional accuracy.
In addition to standard materials, Stellar Alloys Steel Pipes and Tubes also supplies specialized alloys such as Inconel 625 round bar, which provides excellent resistance to heat and corrosion. Customers frequently compare round bar price, stainless rod price, and SS rod price when choosing the right material and supplier.
The cost of round bars can also vary depending on the diameter and grade, for example 10mm rod price or larger diameter bars used in heavy engineering applications. With extensive inventory and reliable distribution, we ensure timely delivery of high-quality bar round steel and round rod products to customers worldwide.

Chemical Composition of Round Bars
The chemical composition of stainless steel round bars and steel round bars varies depending on the grade and application.
Element | Typical Range (%) |
Carbon (C) | 0.03 – 0.30 |
Chromium (Cr) | 10.5 – 25 |
Nickel (Ni) | 0 – 20 |
Manganese (Mn) | Up to 2 |
Silicon (Si) | Up to 1 |
Iron (Fe) | Balance |
These elements help improve corrosion resistance, strength, and durability of steel rounds and stainless round bar products.
Types of Round Bars
Several types of round bars are manufactured to meet different industrial requirements. The most commonly used types include:
Stainless Steel Round Bars
Carbon Steel Round Bars
Alloy Steel Round Bars
Duplex Steel Round Bars

Specification of Round Bars
Round bars are produced according to international standards and industrial specifications.
Specification | Details |
Standards | ASTM A276, ASTM A479, ASTM A182, ASTM A105 |
Diameter | 6 mm to 500 mm |
Length | 3 m to 6 m or customized |
Form | Round |

Heat Treatment & Surface Finishes
Round bars are available in multiple heat treatment conditions to achieve specific mechanical properties: annealed (soft, machinable), solution annealed (corrosion resistant, moderate strength), and quenched & tempered (high strength, hardness). Surface finishes include black (hot rolled, mill scale), bright (cold drawn, smooth), pickled & oiled (descaled, corrosion protection), and polished (mirror finish for decorative applications). Select the appropriate heat treatment and finish based on your application requirements.
Mechanical Properties of Round Bars
Mechanical properties determine the strength and performance of round bars used in engineering structures.
Property | Value |
Tensile Strength | 515 – 750 MPa |
Yield Strength | 205 – 450 MPa |
Elongation | 30 – 40 % |
Hardness | Up to 200 HB |
Note: Mechanical properties vary by grade. Contact us for grade-specific datasheets for 304, 316, 410, 17-4 PH, and other specialty alloys.
Quality Testing & Certifications
Every round bar undergoes rigorous quality testing. We provide EN 10204 3.1 and 3.2 mill test certificates, PMI (Positive Material Identification) reports, tensile & yield strength test results, hardness test certificates, and chemical composition analysis. Additional testing available on request: impact testing, corrosion testing, dimensional inspection reports, and third-party inspection certificates.
