17-4-PH Pipe Fittings
Rose Metal Industries is a trusted Manufacturer, Stockist, and Exporter of premium-quality 17-4 PH Stainless Steel Pipes supplied across Tamil Nadu, Andhra Pradesh, Karnataka, Telangana, Puducherry (Pondicherry), and Andaman & Nicobar Islands. Known for its outstanding combination of high strength, corrosion resistance, and heat treatment flexibility, 17-4 PH stainless steel is widely chosen for demanding industrial applications. Our pipes are manufactured following international standards to ensure superior mechanical performance, dimensional accuracy, and long-lasting durability even in harsh environments..
17-4 PH (UNS S17400) is a precipitation-hardening martensitic stainless steel that achieves exceptional strength through heat treatment. Rose Metal Industries produces 17-4 PH pipes in various tempers such as H900, H1025, H1100, H1150, and Solution Annealed (Condition A), allowing industries to select the most appropriate grade for their operational requirement. These pipes deliver excellent resistance to corrosion, stress cracking, and fatigue, making them ideal for offshore, chemical, and aerospace environments in coastal regions like Chennai, Vizag, Mangaluru, and Puducherry.
Our 17-4 PH Stainless Steel Pipes are manufactured using premium-quality raw materials, advanced melting techniques, and strict quality control. Each pipe undergoes rigorous testing such as UT Test, Hydrostatic Test, PMI Test, Hardness Test, Micro & Macro Analysis, ensuring reliability and performance. Rose Metal Industries maintains ready stock in various wall thicknesses and sizes, ensuring quick delivery to industrial hubs like Coimbatore, Hyderabad, Bengaluru, Vijayawada, and Port Blair.
This grade offers excellent weldability and machinability, making it suitable for components requiring machining after heat treatment. With high yield strength (up to 1100 MPa) and superior toughness, 17-4 PH pipes are used in applications where conventional stainless steels fail to deliver adequate strength. Industries such as petrochemicals, power generation, pulp & paper, marine engineering, and heavy machinery rely heavily on 17-4 PH for high-temperature and high-pressure performance.

Frequently Asked Questions (FAQ)
Q1: What is the difference between 17-4 PH and other stainless steel grades?
A: 17-4 PH offers superior strength and hardness due to precipitation hardening heat treatments. It outperforms grades like 304/316 in mechanical strength, making it ideal for aerospace, marine and high‑pressure fittings.
Q2: Do you provide mill test certificates (MTC)?
A: Yes — Rose Metal Industries provides MTCs, along with PMI testing, hardness testing, tensile test reports and optional third‑party inspection from agencies upon request.
Q3: What standards do your 17-4 PH pipe fittings comply with?
A: We supply 17-4 PH fittings as per ASTM A564, A693, AMS 5643 and customer‑specified standards depending on application and export requirements.
Q4: Can you manufacture custom-shaped or non-standard fittings?
A: Yes — custom elbows, reducers, tees, flanges and precision‑machined fittings can be manufactured with specific tolerances, surface finishes and heat‑treatment conditions like H900, H1025 and H1150.
Q5: Do 17-4 PH pipe fittings perform well in marine and coastal regions?
A: Yes — their high corrosion resistance and excellent mechanical properties make them ideal for coastal states such as Tamilnadu, Andhra Pradesh, Karnataka, Telangana, Puducherry (Pondicherry) and Andaman & Nicobar Islands.
