Stainless Steel 310 Flat Bars
Rose Metal Industries is a renowned manufacturer, stockist and exporter of premium-grade Stainless Steel 310 Flat Bars. Engineered for high-temperature service and long-term durability, our SS 310 flat bars are stocked and shipped to major Indian markets including Tamilnadu, Andhra Pradesh, Karnataka, Telangana, Puducherry (Pondicherry) and the Andaman & Nicobar Islands, as well as exported to global customers across the Middle East, Europe, Africa and Southeast Asia..
SS 310 flat bars combine high chromium and nickel content to deliver exceptional oxidation resistance and strength at elevated temperatures. Rose Metal Industries supplies hot-rolled and cold-finished flat bars suited for furnace parts, heat exchangers, kiln components, and industrial fabrications where resistance to scaling and high-temperature corrosion is critical. We maintain ready stock in common sizes and offer cut-to-length, polishing and precision machining services to meet OEM and project demands..
Our manufacturing and quality systems ensure that every batch of SS 310 flat bar is traceable and supplied with certified documentation. Typical supply conditions include annealed & pickled finish, surface treatments (No.1, 2B, polished), and optional protective packaging for export. Clients in Chennai, Coimbatore, Bengaluru, Hyderabad, Visakhapatnam, Vijayawada and Pondicherry rely on Rose Metal Industries for consistent material quality and prompt deliveries..
SS 310 flat bars are preferred in industries operating under cyclic thermal loads and carburizing atmospheres because they retain mechanical strength and resist creep at temperatures up to about 1100°C. Common applications include furnace supports, brackets, flanges, high-temperature fasteners, and structural elements in petrochemical and thermal power plants. For chloride-rich or highly pitting environments, our technical team can advise on alternative grades such as 316 or duplex stainless steels.

Frequently Asked Questions (FAQ)
Q1: What is the difference between SS 310 and SS 310S?
A: SS 310S has a lower carbon content than SS 310 which improves weldability and reduces the risk of carbide precipitation during welding. Choose 310S for heavy welded fabrications or when post-weld annealing is not feasible.
Q2: Do you provide material test certificates (MTC) for flat bars?
A: Yes — Rose Metal Industries supplies MTCs (EN 10204 3.1/3.2 or as requested) with chemical and mechanical test reports, and we support third-party inspections (SGS, TUV, BV, Lloyd’s) on demand.
Q3: What finishes are available for SS 310 flat bars?
A: Typical finishes include Annealed & Pickled, 2B, No.1, and polished surfaces. Custom surface treatments and machining are available per order.
Q4: Can you supply cut-to-length and machined flat bars to South India?
A: Yes — we supply cut-to-length, machined and finished SS 310 flat bars to Tamilnadu, Andhra Pradesh, Karnataka, Telangana, Puducherry (Pondicherry), Andaman & Nicobar Islands, and for export worldwide.
Q5: Which industries commonly use SS 310 flat bars?
A: Common industries include heat treatment, petrochemical, power generation, cement and kiln manufacturing, marine engineering, and any application requiring high-temperature oxidation resistance.
