Maruti Inox is a stainless steel hot rolled round bars manufacturer and supplier in Gujarat, India. Our SS hot rolled bars are produced from certified stainless steel scrap, melted and rolled in-house to precise dimensions within our vertically integrated facility in Mehsana.
Available in round, square, and hexagonal profiles, the bars are supplied in as-rolled or heat-treated and straightened conditions across 200, 300, and 400 series grades. Manufactured in compliance with ASTM A484 dimensional requirements, they provide a cost-effective starting material for engineering, forging, and secondary machining applications.
What is a Hot Rolled Round Bar?
An SS hot rolled round bar is produced by heating stainless steel continuous cast billets to a suitable rolling temperature and passing them through a series of rolling operations to achieve the required cross-section.
Hot rolling is utilized for larger bar sizes and applications where the material will undergo further machining, fabrication, or forging. Because hot rolled bars have a scaled surface finish from the heating process, they serve as the foundational raw material for secondary cold finishing operations, including the production of cold drawn bright bars and peeled and ground bright bars.
Applications of Hot Rolled Round Bars
Stainless steel hot rolled round bars are commonly used as the starting material for industrial and mechanical applications, including:
- Engineering components and machined parts
- Automotive components, shafts, and pins
- Industrial machinery and heavy fabrication
- Raw material for downstream cold drawing, peeling, and grinding facilities
How to Select the Right Hot Rolled Bar
Selecting the correct hot rolled stainless steel bar ensures efficient downstream processing and final component integrity:
- Material Grade: Select the 200, 300, or 400 series grade according to the corrosion exposure and mechanical requirements of the finished part.
- Bar Shape & Size: Choose round, square, or hexagonal profiles, factoring in the amount of material that will be removed during final machining.
- Supply Condition: Specify as-rolled, heat-treated, or straightened material based on your facility's processing capabilities.
- Required Length: Standardizing lengths (up to 7.0m) helps optimize material handling and reduces cutting waste on the production floor.
Why Source from a Vertically Integrated Manufacturer?
Maruti Inox manufactures hot rolled round bars at our 60,000 MTPA rolling capacity facility in Mehsana, Gujarat. Because our infrastructure integrates melting, continuous cast billet production, and rolling under one roof, we maintain total control over material consistency.
- In-House Quality Control: Material is inspected and tested across our 12+ in-house testing laboratories before dispatch.
- Full Traceability: An official Material Test Certificate (MTC) is issued with every supply, documenting the heat number, chemical composition, and mechanical properties.
- Certified Operations: All manufacturing is conducted under a TÜV SÜD ISO 9001:2015 certified quality management system.

Frequently Asked Questions
1. What sizes of hot rolled round bars do you manufacture?
We manufacture hot rolled round bars in sizes ranging from 16 mm to 180 mm. We also produce square and hexagonal hot rolled bars from 16 mm to 53 mm.
2. What tolerance standard do your hot rolled bars meet?
All of our hot rolled round, square, and hexagonal bars are manufactured in compliance with ASTM A484 dimensional tolerance requirements.
3. What is the difference between hot rolled and cold drawn bars?
Hot rolled bars are shaped at high temperatures, resulting in a scaled surface, making them ideal for heavy fabrication or as a starting material. Cold drawn bars are hot rolled bars that have been pulled through a die at room temperature to achieve precise dimensions and a smooth, bright surface finish.
