17-4-PH Pipe
Rose Metal Industries is a trusted manufacturer, stockist and global exporter of premium‑grade 17‑4 PH stainless steel pipes (UNS S17400 / Type 630 / W. Nr. 1.4542), supplying to industrial clients across Tamilnadu, Andhra Pradesh, Karnataka, Telangana, Puducherry (Pondicherry), and the Andaman & Nicobar Islands — as well as international projects worldwide. 17‑4 PH is a precipitation‑hardening martensitic stainless steel alloy, offering a unique combination of high strength, good corrosion resistance and reliable mechanical performance, making it suitable for demanding environments in chemical processing, petrochemical, marine, oil & gas and heavy‑duty fabrication sectors.
Our 17‑4 PH pipes are manufactured under strict quality control, using premium raw material and advanced forming processes. We offer seamless and welded pipes (depending on customer requirements), with standard and custom sizes, wall thicknesses, end‐preparations (plain end, beveled end), and finish options. This enables clients in industrial hubs such as Chennai, Hyderabad, Bengaluru as well as coastal zones like Puducherry, Port Blair and other island regions to access quality pipes with reliable lead times and export‑ready packaging.
Due to age‑hardening heat treatment, 17‑4 PH pipes deliver high strength, excellent hardness and good toughness — properties essential for components subjected to high pressure, cyclic loading, mechanical stress or corrosive media. These pipes are often selected by industries in Tamilnadu, Andhra Pradesh, Karnataka and Telangana for applications including fluid transport, chemical pipelines, high-pressure systems, and mechanical systems in petrochemical, desalination, marine or offshore infrastructure. The moderate corrosion resistance of 17‑4 PH helps in resisting corrosive agents under many industrial conditions.
Rose Metal Industries maintains a broad inventory of 17‑4 PH pipes in various schedules (from light to heavy), nominal diameters from small bore to large bore and accommodates custom length and thickness requirements. Our export‑oriented logistics ensure safe packaging and documentation for global supply, while domestic distribution covers major markets and coastal states including Andaman & Nicobar Islands, ensuring that even remote or island‑based projects receive timely and certified delivery

Frequently Asked Questions (FAQ)
Q1: Why choose 17‑4 PH Pipes instead of regular stainless steel pipes (304/316)?
A: 17‑4 PH offers much higher strength and hardness (after precipitation‑hardening) compared to austenitic stainless steels, while retaining reasonable corrosion resistance — making it ideal for applications requiring high strength, pressure resistance and durability under stress.
Q2: Do you supply mill test certificates (MTC) and material certification?
A: Yes — Rose Metal Industries provides full MTCs (UNS / ASTM / EN / Type 630 certification), heat‑treatment documentation, and optional third‑party inspection to comply with project and export requirements.
Q3: Are custom pipe sizes, wall thicknesses and end preparations available?
A: Yes — we supply pipes from small bore to large bore (½″ to 48″ or more) in various schedules (SCH 5 to SCH XXS), with plain or beveled ends, and can accommodate custom lengths or welded spool assemblies.
Q4: Are 17‑4 PH Pipes suitable for marine, offshore or coastal applications in coastal states and islands (Tamilnadu, Puducherry, Andaman & Nicobar)?
A: Yes — 17‑4 PH offers good corrosion resistance in many environments and provides high strength and durability. For saltwater service or highly corrosive conditions, ensure proper maintenance and consider appropriate heat treatment for best performance.
Q5: Do you export 17‑4 PH Pipes globally?
A: Absolutely — Rose Metal Industries ships 17‑4 PH pipes domestically across South India and internationally, with export‑grade packing, documentation, and reliable logistics.
