17-4-PH Sheets,Plates and Coils
Rose Metal Industries is a premier manufacturer, stockist and exporter of high-quality 17‑4 PH Sheets, Plates and Coils, serving industrial sectors across Tamilnadu, Andhra Pradesh, Karnataka, Telangana, Puducherry (Pondicherry), and Andaman & Nicobar Islands as well as delivering globally. 17‑4 PH (UNS S17400 / Grade 630) is a precipitation‑hardening stainless steel offering a unique balance of high strength, excellent hardness, good toughness and reasonable corrosion resistance — ideally suited for demanding applications where strength, durability and corrosion resistance are required together
Our 17‑4 PH sheets, plates, and coils are manufactured under strict quality control, using premium-grade stainless steel and processed through controlled hot-rolling, pickling, and finishing. We stock these in various thicknesses, widths and coil/plate sizes to suit diverse industrial needs. This ensures rapid availability for customers in major Indian industrial hubs such as Chennai, Hyderabad, Bengaluru, Visakhapatnam as well as coastal and port zones like Puducherry, Mangalore, Port Blair and Andaman & Nicobar Islands.
Due to its precipitation‑hardening nature, 17‑4 PH achieves high tensile and yield strength, good hardness and fatigue resistance after appropriate heat treatment. This makes the sheets, plates, and coils highly suitable for high‑stress structural components, pressure vessel fabrication, heavy-duty panels, flanges, marine and offshore equipment, and mechanical parts requiring a combination of strength and moderate corrosion resistance. Industries in Karnataka, Andhra Pradesh, Tamilnadu, and Telangana frequently use these materials for petrochemical, desalination, power generation, marine and heavy engineering applications.
Rose Metal Industries offers customization services including cutting-to-size plates/sheets, slit coils, polished/ground finishes, cut-edge or mill-edge, custom lengths, and export‑ready packing. Whether the requirement is a large coil for a fabrication shop in Andhra Pradesh, structural plates for a chemical plant in Tamilnadu, or corrosion‑resistant panels for a coastal installation in Andaman & Nicobar, we ensure timely supply with complete documentation and quality assurance

Frequently Asked Questions (FAQ)
Q1: What makes 17‑4 PH sheets/plates/coils different from standard stainless steels?
A: 17‑4 PH offers precipitation‑hardening capability, which results in high tensile strength, good hardness and fatigue resistance — along with reasonable corrosion resistance — making it superior to standard austenitic stainless steels when strength and durability are critical.
Q2: Do you supply mill test certificates (MTC) and quality documentation?
A: Yes — Rose Metal Industries provides full MTCs (UNS / ASTM / EN / AMS as required), heat‑treatment records, chemical analysis and optional third‑party inspection for export or critical applications.
Q3: What sheet/plate/coils sizes are available and can you provide custom cut-to-size?
A: Yes — we maintain a wide range of thicknesses (from thin coils to heavy plates), widths and lengths/coils, and offer custom cut-to-size or slit-coil services as per project requirements.
Q4: Are 17‑4 PH plates/coils suitable for marine, offshore and coastal applications (for Tamilnadu, Puducherry, Andaman & Nicobar)?
A: Yes — 17‑4 PH provides a good balance of strength and corrosion resistance, making it suitable for many marine, offshore and coastal installations, especially where high strength and durability under load are required.
