Hastelloy Products Supplier in India

Choosing a Hastelloy grade usually starts with the process media. Lakshya Steel supplies Hastelloy products in C-22 and C-276 grades for equipment exposed to acids, chlorides, oxidising chemicals and other demanding process conditions. The available range includes flanges, rods, bars, hex bars, square bars, seamless and welded pipes, tubes, fittings, flat bars, sheets, plates and drawing-based components. Buyers can review Hastelloy C-22 products or send the required grade, product form, size, standard, quantity and testing requirement through the request-a-quote form for a product-specific offer.

The correct selection depends on more than the alloy name. C-22 is often considered where resistance to oxidising and mixed chemical environments is important, while C-276 is widely specified for aggressive chemical processing, pollution-control and chloride-bearing service. Product standards also vary by form, so the specification for a plate, bar, seamless pipe or forged flange should be confirmed separately before ordering.

What Are Hastelloy Products?

Hastelloy is a family of nickel-based alloys developed for corrosive and high-temperature environments. The chemistry differs by grade, which is why C-22 and C-276 should not be presented as interchangeable materials. Both belong to the nickel-chromium-molybdenum family, but the chromium, molybdenum, tungsten and iron balance gives each grade a different corrosion profile. Final selection should be based on the actual chemical concentration, contamination, temperature, pressure, fabrication route and design code.

Fabrication and Welding Guidance

• Confirm the supplied condition and the heat-treatment requirement before fabrication. Wrought C-22 and C-276 products are normally supplied in the mill-annealed condition unless otherwise specified.
• Use clean tools and handling practices that avoid contamination from carbon steel or other shop materials.
• GTAW/TIG, GMAW/MIG and SMAW processes can be used with grade-compatible filler metals and qualified welding procedures.
• Nickel alloys work harden during machining. Use rigid tooling, suitable carbide grades, positive feeds and adequate cooling.
• Hot-formed or heavily cold-worked components may require re-annealing to restore corrosion performance. The final route should follow the alloy producer and project specification.

Testing and Documentation

Depending on the product form and project requirement, buyers may request:

• Mill test certificate with heat-number traceability
• Chemical and mechanical test results
• Positive material identification (PMI)
• Dimensional and visual inspection
• Ultrasonic, hydrostatic or other product-form testing where applicable
• EN 10204 certificate type and third-party inspection, subject to confirmation
• Surface-finish and supplementary testing requirements stated in the purchase order

Related Material Options

Projects that do not require a C-type Hastelloy alloy may also be reviewed against Nickel 200/201 products, Inconel products, Monel 400 and K500 products, or SMO 254 products. The final choice should be based on the process chemistry, temperature, pressure, mechanical requirement and project code rather than the alloy name alone.
