Frequently Asked Questions (FAQ)
Q1: Why choose SS 347 over SS 304 or 316 for sheets, plates & coils?
A: SS 347 is niobium‑stabilized, which prevents carbide precipitation during welding and high‑temperature exposure; this results in superior intergranular corrosion resistance and better high‑temperature performance compared to regular SS 304.
Q2: Do you supply SS 347 Sheets, Plates & Coils to South Indian states and island territories?
A: Yes — we supply across Tamil Nadu, Andhra Pradesh, Karnataka, Telangana, Puducherry (Pondicherry), and Andaman & Nicobar Islands with ready inventory and export‑ready logistics.
Q3: Are custom sizes, thicknesses and finishes available?
A: Yes — we offer custom thicknesses, widths, coil sizes, cut‑to‑size plates, surface finishes (hot rolled, cold rolled, pickled, polished), and special order specifications.
Q4: Can you provide material certification and third‑party inspection?
A: Yes — we provide full mill test certificates (MTC 3.1 / 3.2), chemical & mechanical test reports, and can arrange third‑party inspection on demand for quality assurance.
Q5: What are the main industries where SS 347 Sheets, Plates & Coils are used?
A: Industries such as petrochemical, marine & offshore, power generation, chemical processing, food & pharmaceutical, shipbuilding, and heavy fabrication — particularly where high-temperature, corrosion resistance and durability are critical.
