Stainless Steel 310 Square Rods
Rose Metal Industries is one of the most trusted and established manufacturers, stockists and global exporters of Stainless Steel 310 / 310S Square Rods, delivering premium high-temperature stainless steel across Indian industrial hubs and international markets. SS 310 is an austenitic chromium–nickel stainless steel specially designed for elevated-temperature operations, offering outstanding resistance to oxidation, carburization and thermal fatigue. SS 310S, the low-carbon modification, is widely preferred in applications where frequent welding is required without the risk of carbide precipitation. Our square rods are manufactured using high-grade billets, advanced rolling technology and stringent quality control to ensure excellent surface finish, dimensional stability and mechanical performance.
With strong supply capabilities, Rose Metal Industries caters to diverse engineering, fabrication and manufacturing sectors across Tamilnadu, Andhra Pradesh, Karnataka, Telangana, Puducherry (Pondicherry) and the Andaman & Nicobar Islands. These coastal and industrial regions demand materials that can withstand high-temperature processing, saline atmospheres and corrosive industrial conditions—making SS 310 an ideal choice. Industrial clusters such as Chennai, Coimbatore, Bengaluru, Hyderabad, Visakhapatnam, Mangalore, Puducherry and Port Blair benefit from our fast deliveries, large inventory and custom supply options. Our global export network covers the Middle East, Africa, Europe, Southeast Asia and South America, supported by seaworthy packaging and complete material certification..
SS 310 / 310S Square Rods supplied by Rose Metal Industries exhibit exceptional resistance to oxidation up to 1100°C in continuous service and 1035°C in intermittent service, making them suitable for high-heat environments. Due to their high chromium (24–26%) and nickel (19–22%) content, these square rods perform exceptionally well in carburizing atmospheres, furnace linings, heat treatment fixtures, burners, kiln components and combustion chambers. In addition, their strong creep strength and minimal distortion under thermal cycling make them the preferred material for heavy-duty thermal applications compared to standard stainless steels like 304 or 316.
We manufacture SS 310 Square Rods in multiple conditions such as hot rolled, cold drawn, centerless ground and polished finishes. Precision machining ensures uniform square edges and consistent dimensions suitable for further fabrication, CNC machining and structural use. Customers frequently choose our products for fabrication of support brackets, heat exchanger components, fixtures, fasteners, machine shafts and custom engineering parts. Rose Metal Industries also provides customized cut-to-length services, surface finishing, export-grade wrapping, and tailored size availability to support OEM manufacturing, EPC projects and large-scale industrial requirements

Frequently Asked Questions (FAQ)
Q1: What is the difference between SS 310 and 310S square rods?
A: 310S is the low-carbon variant of 310 (lower C content) which reduces carbide precipitation during welding and improves post-weld corrosion resistance. 310 offers slightly higher high-temperature strength due to higher carbon content.
Q2: Do you provide Mill Test Certificates (MTC) and inspection reports?
A: Yes — Rose Metal Industries supplies MTCs (EN 10204/3.1) with shipments and can arrange third-party inspection, PMI and additional testing on request.
Q3: Can you supply custom sizes and surface finishes for export?
A: Yes — we offer custom edge sizes, lengths, cut-to-length options, centerless grinding, polishing and export-grade packing for international shipments.
Q4: Are SS 310 square rods suitable for use in coastal or island locations like Tamilnadu and Andaman & Nicobar?
A: SS 310 provides good oxidation and high-temperature corrosion resistance but for highly chloride-rich marine environments, grades such as 316 or duplex may be preferable depending on service conditions. We advise application-specific material selection.
Q5: What are typical applications of 310 square rods in India?
A: Common uses include furnace and heat-treatment fixtures, petrochemical plant parts, boiler components, and specialized machine parts supplied to industrial centres across Tamilnadu, Andhra Pradesh, Karnataka, Telangana, Puducherry and the Andaman & Nicobar Islands.
