Hastelloy Pipe
Hastelloy Pipe Fittings offered by Rose Metal Industries are engineered to deliver exceptional corrosion resistance and durability in the most aggressive industrial environments. As a leading manufacturer, stockist, and global exporter, the company supplies premium-grade Hastelloy fittings in various forms such as elbows, tees, reducers, caps, stub ends, and customized fittings. These fittings are widely demanded across Tamil Nadu, Andhra Pradesh, Karnataka, Telangana, Puducherry (Pondicherry), and the Andaman & Nicobar Islands, supporting industries that handle strong acids, chlorides, seawater, and elevated temperature processes. With decades of experience and a strong global supply network, Rose Metal Industries ensures consistent quality and timely delivery for both domestic and international clients..
Hastelloy Pipe Fittings are produced using nickel–molybdenum and nickel–chromium–molybdenum alloys such as Hastelloy C276, C22, C2000, and B2, which exhibit superior resistance to pitting, crevice corrosion, and stress corrosion cracking. The chemical composition of Hastelloy, rich in nickel and molybdenum, enhances its resistance to reducing environments, while chromium provides excellent protection in oxidizing media. These properties make Hastelloy fittings suitable for chemical plants, pharmaceuticals, seawater systems, pollution control equipment, and high-temperature reactor vessels. Rose Metal Industries supplies fittings in seamless, welded, and fabricated options depending on the application requirements.
In terms of mechanical strength, Hastelloy Pipe Fittings offer high tensile strength, exceptional yield strength, and excellent flexibility, making them suitable for high-pressure and high-temperature applications. The fittings maintain structural stability even in extreme conditions, ensuring safe and reliable operation across pipeline systems. They are manufactured following international standards like ASTM B366, guaranteeing precise dimensions, excellent weldability, and long service life. Rose Metal Industries conducts thorough quality control, including PMI testing, hardness tests, mechanical tests, and hydrostatic examination to ensure each fitting meets global engineering expectations..
The fittings are available in a wide dimensional range to meet varied industrial needs. Standard sizes include ½” NB to 24” NB in seamless and welded forms, with thickness schedules ranging from SCH 10 to SCH XXS. Customized sizes, heavy-wall fittings, and special-radius elbows are also supplied based on project specifications. These dimensional options make Hastelloy Pipe Fittings highly versatile for industries in Chennai, Coimbatore, Bengaluru, Hyderabad, Visakhapatnam, Mysuru, Puducherry, and Port Blair, where harsh coastal and industrial environments demand reliable corrosion-resistant materials..

Frequently Asked Questions (FAQ)
Q1: What is the difference between 304 and 304L?
A: 304L has a lower maximum carbon content (≤0.03%) which reduces the risk of sensitization during welding, making it preferable for heavy gauge welded components. Mechanical properties are similar; choose 304L when welding without post-weld anneal is required.
Q2: Do you provide mill test certificates (MTC)?
A: Yes — Rose Metal Industries issues MTCs and can facilitate third-party inspection and PMI/chemical analysis on request.
Q3: What standards do your round bars comply with?
A: We supply material to customer-specified standards including ASTM A276 / A479 and EN standards (e.g., EN 10088 series) depending on product form and destination requirements.
Q4: Can you supply custom diameters, lengths and surface finishes?
A: Yes — we offer cut-to-length, turned/bright finish, polishing and custom tolerances. Contact sales for lead times and minimum order quantities.
Q5: How should I select 304 vs 316 for corrosion resistance?
A: 304 is suitable for many indoor and mildly corrosive environments. For chloride-rich environments (marine, salt-spray, swimming pools) or higher corrosion resistance needs, consider 316 (higher Mo content). Our sales team will advise based on application.
