17-4-PH Hexagon Rods
Rose Metal Industries is a reputed manufacturer, stockist, and global exporter of high‑quality 17‑4 PH Hexagon Rods (UNS S17400 / Grade 630 / EN 1.4542), serving industrial clients across Tamilnadu, Andhra Pradesh, Karnataka, Telangana, Puducherry (Pondicherry), and the Andaman & Nicobar Islands, along with international markets worldwide. 17‑4 PH stainless steel is a martensitic, precipitation‑hardening alloy that combines excellent strength, good hardness, and moderate corrosion resistance — well suited for load‑bearing, high‑stress, and cyclic applications in demanding environments
Our 17‑4 PH hexagon rods are produced using premium raw materials and precise manufacturing processes: hot‑rolling or bright‑bar production, followed by optional cold drawing or centerless grinding. We maintain a comprehensive stock in multiple hex‑sizes and lengths to promptly supply fabrication houses, OEMs, and industrial clients in domestic hubs like Chennai, Hyderabad, Bengaluru, and coastal/port regions such as Puducherry and Port Blair. Export‑ready packaging ensures safe delivery to overseas customers
After age‑hardening heat treatment (various “H” tempers like H900, H1025, H1150, depending on requirements), 17‑4 PH hex rods exhibit high tensile and yield strength along with good hardness and fatigue resistance. This makes them especially suitable for critical mechanical components — shafts, bolts, fasteners, structural pins, valve stems, pump parts — which require reliable performance even under cyclic load or moderately corrosive conditions (such as coastal or industrial chemical atmospheres commonly found in Tamilnadu, Andhra Pradesh, and other coastal/industrial zones).
Rose Metal Industries offers custom sizes, cut‑to‑length service, various surface finishes (bright, ground, polished) and mechanical certification documentation (MTC, heat‑treatment record) to meet both domestic and export requirements. Whether for a heavy engineering project in Karnataka, an offshore or marine installation near Andaman & Nicobar, or a global supply contract, our 17‑4 PH hexagon rods combine high performance, reproducible quality and export‑class dispatch readiness.

Applications of 17‑4 PH Hexagon Rods
- Pump shafts, valve stems, fasteners and mechanical components in oil & gas, petrochemical and chemical plants
- Shafts, couplings, gears, pins and structural components in heavy machinery and industrial equipment
- Aerospace parts, landing gear components, structural pins requiring high strength-to-weight ratio
- Marine and offshore components — shafts, couplings, fittings, and fasteners — suitable for coastal and island regions such as Puducherry and Andaman & Nicobar Islands due to moderate corrosion resistance
- Refinery, desalination, power plants, and chemical processing units where corrosion resistance + high strength are required
- Export‑oriented engineering and fabrication projects needing certified, high‑quality hex bars with global traceability
The versatility of 17‑4 PH hexagon rods makes them suitable across a broad spectrum of industries: oil & gas, petrochemical, marine & offshore, chemical processing, power generation, heavy machinery, aerospace and general engineering. Their strength, hardness, and corrosion‑resistance balance make them a preferred choice for components where safety, durability and long‑term reliability are critical.
At Rose Metal Industries, we commit to global quality standards, traceability, and customer satisfaction — ensuring that every 17‑4 PH hexagon rod delivered to clients in Tamilnadu, Andhra Pradesh, Karnataka, Telangana, Puducherry & Andaman & Nicobar Islands — or internationally — meets stringent quality and performance expectations.
Frequently Asked Questions (FAQ)
Q1: Why choose 17‑4 PH Hexagon Rods instead of standard stainless steels or carbon steels?
A: 17‑4 PH combines high strength, excellent hardness (after aging), good fatigue and wear resistance — significantly higher than standard austenitic stainless steels — while retaining moderate corrosion resistance, making it ideal for high-stress, load-bearing, and cyclic applications.
Q2: Do you supply mill test certificates (MTC) and material traceability?
A: Yes — Rose Metal Industries provides full MTCs (UNS / ASTM / EN / AMS as required), heat‑treatment records, and third‑party inspection documentation on request to ensure compliance with project and export standards.
Q3: In what sizes and lengths are 17‑4 PH hex rods available?
A: We supply a wide range of flat‑to‑flat hex sizes (from small ~6 mm up to large ~150 mm or more depending on mill capacity), in standard and custom lengths (typically 500 mm to 6000 mm or custom cut‑to‑length) with various surface finishes.
Q4: Are 17‑4 PH Hexagon Rods suitable for marine or coastal applications like those in Tamilnadu, Puducherry or Andaman & Nicobar Islands?
A: Yes — while 17‑4 PH has moderate corrosion resistance (generally comparable to austenitic grades in many environments), when properly heat-treated and maintained it performs reliably in marine, petrochemical, offshore or coastal applications requiring strength and durability.
Q5: Do you export 17‑4 PH Hexagon Rods globally as well as supply in South India?
A: Absolutely — Rose Metal Industries serves customers across Tamilnadu, Andhra Pradesh, Karnataka, Telangana, Puducherry and Andaman & Nicobar Islands, and also exports globally with export‑ready packaging, certification and reliable logistics.
