Stainless Steel 304/304L Round Rods
Rose Metal Industries is a leading manufacturer, stockist and exporter of Stainless Steel 304 and 304L Round Rods. Our 304/304L rods are produced to meet international quality expectations and are stocked for immediate supply to industrial and commercial customers. We serve extensive domestic markets throughout Tamilnadu, Andhra Pradesh, Karnataka, Telangana, Puducherry (Pondicherry) and the Andaman and Nicobar Islands, and we export globally to customers seeking reliable stainless round bars for fabrication, engineering and OEM work.
Manufactured with close process control, our SS 304 / 304L round rods are available in multiple diameters and finishes — bright-turned, polished and annealed — and supplied as cut-to-length bars or full-length stock. Rose Metal Industries acts as both a trusted domestic stockist for fast local delivery across South India and as a dependable exporter for international projects, offering consistent material traceability, packing and shipping services.
Stainless Steel 304 (also known as A2 stainless) is the most widely used austenitic stainless alloy for general-purpose corrosion resistance, while 304L (low carbon variant) improves weldability and reduces carbide precipitation during welding. Both grades are highly versatile — found in food processing, architectural, chemical, marine and automotive components — and are commonly specified where good formability, corrosion resistance and hygiene are required..
Customers in Tamilnadu, Andhra Pradesh, Karnataka, Telangana, Puducherry and the Andaman and Nicobar Islands choose Rose Metal Industries for reliable stock levels, quick turnaround and export-ready documentation. Whether you need small quantities for local fabrication or bulk shipments for an international project, our SS304/304L round rods are packaged and tested to meet buyer requirements.

Frequently Asked Questions (FAQ)
Q1: What is the difference between 304 and 304L?
A: 304L contains a lower maximum carbon content (≤0.03%), which minimizes the risk of carbide precipitation during welding. This makes 304L ideal for heavy-gauge welded components where post-weld annealing is not feasible. Both grades offer similar corrosion resistance and mechanical properties.
Q2: Do you provide mill test certificates (MTC)?
A: Yes — Rose Metal Industries provides complete Mill Test Certificates (MTC) and can arrange third-party inspections, PMI testing, and chemical analysis as per customer requirements.
Q3: What standards do your Stainless Steel 304/304L Round Rods comply with?
A: Our round rods are supplied according to internationally accepted specifications including ASTM A276, ASTM A479, ASME SA276, EN 10088, and other customer-specific standards depending on destination and application.
Q4: Can you supply custom diameters, lengths and surface finishes?
A: Yes — we offer customized diameters, cut-to-length options, bright-drawn or polished surface finishes, and special tolerances. Contact our sales department for availability, lead times, and minimum order quantities.
Q5: How should I select between 304 and 316 for corrosion resistance?
A: 304 is suitable for general engineering, indoor use, food processing, and mildly corrosive environments. For higher chloride exposure—such as marine, coastal, swimming pools or chemical atmospheres—316 is a better choice due to its molybdenum (Mo) addition. Our technical team can guide you based on your specific application.
