Hastelloy C22 Sheets & Plates

Material Specifications & International Standards

Every Hastelloy C22 alloy sheet we supply is traceable to ASTM B575 and ASME SB575, under UNS N06022. Thickness runs from 0.5 mm up to 100 mm, and width goes up to 2500 mm if needed. Finishes include 2B, No. 1, No. 4, and mirror polish. Custom cutting is also available, whether it's a small fabrication batch or a bulk order for a pressure vessel job.

EQUIVALENT GRADE OF Hastelloy Alloy C22 Sheets, Plate & Coils

Production of Alloy C22 Sheets/Plates

It starts with vacuum induction melting, keeping carbon content under 0.015%. Hot rolling brings the plate to thickness. Then we perform solution annealing at 1120°C, followed by a fast water dilution to lock in the microstructure before it ever reaches our stockyard. Mills producing Hastelloy C22 plates have to hold tight tolerances here. A 5% variance on a 50mm plate sounds small, but it can disrupt the weld procedure calculations on site.

Performance Advantages of Hastelloy C22 Sheets/Plates

Sites that switch to this alloy tend to have fewer shutdowns in the first year of use. Equipment lasts longer under aggressive media, and replacement frequency drops, approximately half compared to standard stainless in chloride-heavy service. Maintenance costs come down as localized corrosion usually forces an unplanned vessel inspection and doesn't develop well on properly welded C22 surfaces. It can be formed and welded using normal shop equipment, with no special preheat required. In high-temperature equipment, the mechanical properties remain stable during continuous service up to 550°C, and the resistance to pitting remains reliable even in seawater or wet chlorine.

Quality Assurance & Value-Added Services

Every plate can be traced back to its heat number, from the mill right through to dispatch. Each shipment comes with a mill test certificate, showing chemical composition and mechanical test results. Third-party inspection can be arranged on request through agencies like SGS or Bureau Veritas. Precision cutting is also available for fabrication drawings, which reduces scrap for buyers who are watching material costs closely. We also support custom fabrication, rolling, and forming for pressure vessel shells. Export packaging uses moisture barrier wrapping and steel crating is built for ocean freight, and in-stock items are usually dispatched within 5-7 working days of order confirmation.

Industries That Depend on Hastelloy C22 Plates

Plants handling aggressive chemistry need this alloy where low quality materials would break down within a single run.

• Chemical manufacturing: copes with mixed acids, wet chlorine, and hypochlorite without pitting the way standard alloys do.
• Fertilizer plants: holds up against phosphoric and sulfuric acid mixtures used in ammonium phosphate lines.
• Pharmaceutical processing: resists oxidizing acids from active ingredient synthesis and meets cleanliness standards for batch reactors.
• Marine engineering: tolerates seawater chloride exposure on flanges, fasteners, and heat exchanger parts.
• Oil & Gas: performs in sour gas conditions with hydrogen sulfide and carbon dioxide under pressure.
• Pollution control systems: survives flue gas desulfurization units, where wet-dry chloride cycling wears out carbon steel fast.
• Heat treatment plants: keep their strength through repeated thermal cycling in furnace fixtures and baskets.
• Power generation: resists corrosion in scrubber systems handling sulfurous combustion byproducts.

Why Customers Choose Triton Alloys

A large ready inventory across common thicknesses means buyers skip the 8-12 week wait that comes with mill-direct orders. Quality stays consistent, since every heat goes through the same testing before it's released. RFQs receive responses within 24 hours on working days. Bulk supply is available for container-load orders, useful for EPC contractors. Deliveries go out to sites across Maharashtra and Gujarat as well as international buyers through established freight forwarders, and after-sales support covers documentation queries and re-certification requests when they come up.
