Key Features

• Excellent Weldability — SS 304 can be welded using all standard welding methods without requiring post-weld annealing for most applications, making it highly versatile in fabrication.
• High Strength at Elevated Temperatures — Retains mechanical integrity at temperatures up to 870°C, making it suitable for heat exchangers, boilers, and furnace components.
• Hygienic & Non-Toxic Surface — Non-porous, easy-to-clean surface makes SS 304 the preferred material in food, beverage, dairy, and pharmaceutical piping systems.
• Outstanding Formability — Easily drawn, formed, and shaped into complex configurations, making it suitable for custom piping designs and precision tube fabrications.
• Superior Corrosion Resistance — The passive chromium oxide layer provides strong protection against rust, moisture, acids, and oxidizing environments, extending service life significantly.
• Aesthetically Versatile — Available in multiple surface finishes from matte 2B to mirror-polished No. 8, ideal for architectural and decorative applications.
• Cold Workable — Both hardness and tensile strength can be improved through cold working without compromising corrosion resistance.
• Intergranular Corrosion Resistance — Low carbon content minimizes carbide precipitation at grain boundaries during welding, maintaining corrosion resistance in heat-affected zones.

Chemical Composition – SS 304 Grade

Element	Content (%)
Chromium (Cr)	18.00 – 20.00
Nickel (Ni)	8.00 – 10.50
Carbon (C)	≤ 0.08
Manganese (Mn)	≤ 2.00
Silicon (Si)	≤ 0.75

Why SS 304 Grade Is the Right Choice

When compared to lower grades like SS 202, the superior nickel and chromium content in SS 304 gives it significantly better corrosion resistance, especially in outdoor, marine environment of Andamans, and mildly acidic environments.

SS 304 offers the ideal balance of performance, workability, hygiene, and cost — making it the go-to grade for engineers, architects, procurement managers, and fabricators worldwide.

Frequently Asked Questions (FAQs)

Q: What is the difference between SS 304 and SS 304L pipes? SS 304L has a lower carbon content (max 0.03% vs 0.08% in 304), which minimizes the risk of intergranular corrosion in welded components. For most standard applications, both are interchangeable.

Q: Are Jindal SS 304 pipes compliant with ASTM A312? Yes. Jindal SS 304 pipes are manufactured in compliance with ASTM A312 / ASME SA312 standards and are supplied with full mill test certificates.

Q: Can these pipes be used in food-grade or pharmaceutical applications? Absolutely. SS 304's non-toxic, non-porous surface and excellent resistance to mild acids make it the industry standard for food, dairy, beverage, and pharmaceutical piping.
