Stainless Steel Round bar Suppliers In Mumbai, Buy Large Or Small Quantity ASTM A276 Round Bar At Discounted Price In India
Since stainless steel bars are shaped and are available in many forms like flat, hexagonal or hex, round, and square. Mostly, the form of the bar defines its use in the application area or forte. Besides being available in different forms or shapes, Stainless steel bars are made available in a variety of sizes by the SS Round Bar Manufacturer In India depending on the applications and utilizations of the industry.
The Hot Rolled Stainless Steel Round Bar has more absolute roughness than the drawn bars. This is not a concern when the bars are used only for the strength and corrosion-resistant properties. But when the bars are used in aesthetic applications and outdoor fixtures, the Cold Drawn Stainless Steel Round Bar is preferred because it has smooth surface and less absolute roughness. The bars can also vary in sizes. The general range is 5mm to 450mm radius. Please contact us for a complete SS Round Bar Size Chart and the pricing.

Understanding Stainless Steel Round Bar: Versatile Material for Modern Industry
A stainless steel round bar represents one of the most versatile and widely used forms of stainless steel stock material. These cylindrical bars combine the inherent advantages of stainless steel—exceptional corrosion resistance, high strength, and aesthetic appeal—with a shape that facilitates machining, forging, and fabrication into countless end products. From precision turned components to structural supports, stainless steel round bar serves as the foundation for manufacturing operations across virtually every industrial sector.
The cylindrical geometry of round bars offers distinct advantages over other bar shapes in many applications. The uniform cross-section simplifies machining operations, enabling efficient production of shafts, pins, fasteners, and valve components. The absence of sharp corners reduces stress concentrations, making round bars particularly suitable for applications involving rotating equipment, cyclic loading, or impact forces. This combination of geometric simplicity and material performance has established stainless steel round bar as an indispensable material in modern manufacturing.

Hot Rolled and Cold Drawn Options
The manufacturing process significantly influences the characteristics of stainless steel round bar products. Hot rolled bars are produced at elevated temperatures, resulting in products with greater absolute roughness and a mill scale surface finish. These bars are ideal for applications where strength and corrosion resistance are the primary requirements, and surface aesthetics are secondary. The hot rolling process enables production of larger diameter bars economically, making it the preferred method for structural components and heavy machinery parts.
Cold drawn stainless steel round bar products offer superior surface finish and tighter dimensional tolerances. The cold working process produces a smooth, bright surface with minimal roughness, making these bars ideal for aesthetic applications, outdoor fixtures, and precision machined components where surface quality directly impacts performance or appearance. The cold drawing process also increases material strength through work hardening, providing enhanced mechanical properties for demanding applications.
Premium 304 Stainless Steel Round Bar for General Applications
Our 304 stainless steel round bar represents the most widely specified grade for general-purpose applications across numerous industries. This austenitic chromium-nickel alloy delivers outstanding corrosion resistance in atmospheric environments, making it suitable for everything from architectural hardware to food processing equipment. The non-magnetic properties of stainless steel round bar 304 prove valuable in electronic equipment, medical devices, and instrumentation where magnetic interference must be avoided.
The excellent formability and machinability characteristics of 304 stainless steel round bar facilitate efficient manufacturing operations. This grade machines cleanly with proper tooling and cutting parameters, producing quality surface finishes and dimensional accuracy essential for precision components. The weldability of 304 grade enables fabrication of complex assemblies without risk of intergranular corrosion in most service environments.
When properly specified and maintained, stainless steel round bar 304 delivers decades of reliable performance across diverse applications. From marine hardware exposed to saltwater spray to pharmaceutical equipment requiring sanitary conditions, this versatile grade serves reliably in countless installations worldwide. The widespread availability and proven track record of 304 round bar make it the default choice for many engineering applications.
Superior 316 Grade for Enhanced Corrosion Resistance
For environments demanding enhanced corrosion protection, our grade 316 stainless steel round bar provides superior performance through the addition of molybdenum to the chromium-nickel base. This alloying element dramatically improves resistance to pitting and crevice corrosion caused by chlorides, making 316 grade indispensable in marine applications, coastal installations, chemical processing facilities, and pharmaceutical manufacturing operations.
The superior corrosion resistance of 316 stainless steel round bar translates directly into extended service life and reduced lifecycle costs in aggressive environments. Applications involving acidic conditions, chloride exposure, or elevated temperatures particularly benefit from the enhanced material properties of this premium grade. Industries from offshore oil platforms to pulp and paper mills specify 316 round bar for critical components where material failure could compromise safety or operational continuity.
Specialized Grades for Extreme Service Conditions
Beyond standard 304 and 316 grades, our stainless steel round bar portfolio includes specialized alloys engineered for extreme service conditions. Grade 310 offers exceptional high-temperature performance, maintaining strength and oxidation resistance at temperatures where ordinary grades would quickly deteriorate. This makes 310 round bar essential for furnace components, heat treatment fixtures, and thermal processing equipment.
Grade 321 with titanium stabilization resists intergranular corrosion in welded assemblies exposed to elevated temperatures, making it valuable in aircraft exhaust systems and high-temperature chemical processing equipment. The precipitation hardening grade 17-4PH provides exceptional strength combined with good corrosion resistance for applications requiring high mechanical performance, including aerospace components and oil field equipment.
Super austenitic grade 904L round bars deliver exceptional resistance to sulfuric acid and other aggressive chemicals through their high nickel, chromium, and molybdenum content. Duplex grades S31803 and super duplex S32760 combine high strength with excellent corrosion resistance, enabling lighter-weight designs in marine and offshore applications.

This comprehensive product range enables customers to source optimal bar configurations from a single reliable supplier.
Surface Finishes and Processing Options
Surface finish significantly impacts both the performance and economics of stainless steel round bar applications. Cold drawn bright finish provides excellent surface quality for aesthetic applications and components requiring minimal surface preparation before use. Hot rolled pickled and oiled finish removes mill scale while providing corrosion protection during storage and shipment. Centerless ground finish delivers the tightest dimensional tolerances and superior surface finish for precision machined components.
