Hastelloy Angles and Channels
Hastelloy Angles and Channels from Rose Metal Industries are premium nickel-based structural sections engineered for extreme corrosion and high-temperature environments. Manufactured, stocked, and exported with strict quality control, these structural members combine the superior chemical resistance of Hastelloy alloys with the mechanical strength required for industrial frames, supports and skids. Industries across Tamilnadu, Andhra Pradesh, Karnataka, Telangana, Puducherry (Pondicherry) and the Andaman & Nicobar Islands rely on these sections for long-life performance in aggressive process and coastal conditions..
Produced in commonly specified grades such as Hastelloy C-276 (UNS N10276) and C-22 (UNS N06022), our angles and channels are made using controlled melting and rolling processes to ensure consistent chemistry and homogenous microstructure. The alloy chemistry — a high nickel base with chromium, molybdenum and in some grades tungsten or cobalt — gives these sections outstanding resistance to pitting, crevice corrosion and stress-corrosion cracking in both oxidizing and reducing environments. This makes them especially suitable for chemical plants, desalination and seawater systems, and offshore installations..
Mechanically, Hastelloy angles and channels offer a robust combination of tensile strength and ductility that supports heavy structural loading while allowing for fabrication operations like welding, drilling and machining. Typical mechanical behaviour provides adequate yield and tensile levels for support frames, heat-exchanger saddles, platforms and equipment mounts, and the material retains stability at elevated temperatures — a key advantage for furnace supports, exhaust systems and power-plant auxiliaries. Rose Metal Industries supplies these sections with full test documentation (MTC) and options for solution-annealed or pickled finishes to suit installation requirements..
Available in a wide range of standard leg/width and thickness combinations and lengths up to project needs, our Hastelloy angles (L-sections) and channels (C/CH-sections) can be stocked or produced to order. Standard stock sizes cover light instrument supports through to heavy structural members; custom sizes, tight tolerances and value-added processing (cut-to-length, drilling, notching, shot-blasting or painting) are provided to reduce on-site work and speed erection. This flexibility benefits EPC contractors and fabricators working on projects throughout Southern India and for export customers worldwide..

Typical Applications
- Furnace frameworks, platforms and structural supports
- Heat exchanger supports, piping supports and skids
- Offshore structural members, coastal installations and marine fabrication
- Chemical and petrochemical plant structural components
- Power generation supports, nuclear auxiliary structures
- Corrosion-resistant cable trays, ladders and fabrication parts
Typical applications for Hastelloy angles and channels include furnace frameworks, heat-exchanger supports and saddles, offshore platforms and marine structures, chemical plant structural members, cable trays and ladder supports in corrosive atmospheres, and any application where long service life in aggressive media is essential. Because coastal and island locations such as Puducherry and the Andaman & Nicobar Islands expose structures to severe chloride attack, Hastelloy structural sections are often selected there and in coastal industrial zones of Tamilnadu and Andhra Pradesh for their superior longevity..
Rose Metal Industries couples product quality with technical support and logistics to serve both domestic and international markets. We provide material traceability, PMI/chemical analysis, dimensional inspection and supply chain solutions so clients in Karnataka, Telangana, Tamilnadu, Andhra Pradesh, Puducherry and the Andaman & Nicobar Islands — as well as overseas buyers — receive Hastelloy angles and channels that meet engineering specifications and deliver dependable, low-maintenance performance in the harshest environments..
