Stainless Steel 316/316L Square Rods
Rose Metal Industries is a leading manufacturer, stockist, and exporter of Stainless Steel 316/316L Square Rods, supplying high-quality materials to industrial, architectural, marine, and fabrication sectors. Known for superior corrosion resistance, strength, and durability, SS 316/316L square rods are widely used in applications that require long-term reliability. Our products are delivered across Tamilnadu, Andhra Pradesh, Karnataka, Telangana, Puducherry (Pondicherry), and the Andaman & Nicobar Islands, with global exports to Europe, the Middle East, Africa, and Southeast Asia.
SS 316 and 316L square rods contain chromium, nickel, and molybdenum, giving them exceptional resistance to pitting, crevice corrosion, and chloride environments. The 316L variant, with lower carbon content, is ideal for welding and reduces the risk of carbide precipitation. Rose Metal Industries manufactures these rods in hot-rolled, cold-drawn, bright, and polished finishes to meet both domestic and international quality standards..
Industries in Chennai, Bengaluru, Hyderabad, Visakhapatnam, Mangalore, Vijayawada, Puducherry, and Port Blair rely on our SS 316/316L square rods for marine, chemical, and industrial applications. The rods are suitable for use in seawater, coastal environments, desalination plants, chemical processing equipment, pump and valve shafts, and structural components where corrosion resistance and mechanical strength are critical..
Our square rods comply with internationally recognized standards such as ASTM A276, ASTM A479, ASME SA276, and EN 10088, and are supplied with Mill Test Certificates (MTC) and third-party inspection on request. They offer high tensile strength, yield strength, elongation, and toughness, making them suitable for precision machining, threading, welding, and fabrication processes for both heavy-duty and light-duty.

Frequently Asked Questions (FAQ)
Q1: What is the difference between 316 and 316L square rods?
A: 316L has a lower maximum carbon content (≤0.03%) which reduces the risk of carbide precipitation during welding and improves post-weld corrosion resistance. Mechanical performance is similar; choose 316L for heavy welding without post-weld annealing.
Q2: Do you provide Mill Test Certificates (MTC) and inspection reports?
A: Yes — Rose Metal Industries supplies MTCs (EN 10204/3.1 or equivalent), and can arrange PMI testing and third-party inspection on request for domestic or export shipments.
Q3: What surface finishes and sizes are available for square rods?
A: We supply hot-rolled, cold-drawn, bright-turned, centerless-ground and polished square rods. Standard and custom sizes from small sections (3–6 mm) up to large sections (150 mm and above) are available with cut-to-length options.
Q4: Can you ship to South India and island territories?
A: Yes — we deliver across Tamilnadu, Andhra Pradesh, Karnataka, Telangana, Puducherry and remote regions including the Andaman & Nicobar Islands. Export packing and documentation are provided for international shipments.
Q5: Which standards do your SS 316/316L square rods conform to?
A: Our square rods are manufactured to ASTM A276 / A479, ASME SA276 and EN 10088 standards and can be supplied to customer-specific tolerances and inspection requirements.
