What Are ASTM B575 Hastelloy C22 Plates and Why Do EPC Buyers Choose Them Over Other Alloys?

Hastelloy C22 is a nickel-chromium-molybdenum alloy with superior resistance to both oxidizing and reducing agents. Unlike standard stainless steels or lower-grade alloys, C22 plates offer:

  • Outstanding Resistance – withstands seawater, chlorides, and mixed industrial chemicals
  • Proven Reliability – performs in sour gas, chemical reactors, and desalination plants
  • High Temperature Endurance – stable under thermal cycling & acidic vapors
  • Global Compliance – supplied to ASTM B575 / ASME SB575 standards

For industries where failure is not an option, Hastelloy C22 plates ensure long-term protection and compliance.

The Common Procurement Risks Buyers Face When Sourcing Hastelloy C22 Plates

Every engineer and buyer knows the risks:

  • Receiving wrong grades or substitutes instead of certified C22
  • Lack of NACE / PED / EN 10204 documents → rejection in project audits
  • Overpriced quotes with hidden costs for CIF/FOB supply
  • Transit damages like dents, rust, or edge cracks
  • Late deliveries that stall EPC shutdown timelines

At Navgraha Steels INC, we eliminate these risks by providing:

  • Only Certified Supply – ASTM, NACE, PED, IBR approvals
  • Seaworthy Packaging – rust-proof wrapping, edge guards, wooden pallets
  • Mumbai Stock + Mill Allocations – ready for urgent dispatch
  • Transparent Pricing – CIF, FOB, and door-to-site clarity
  • Audit-Ready Docs – EN 10204 MTCs, TPI reports (SGS, Lloyd’s, TUV, BV)

Applications of Hastelloy C22 Plates in Chemical, Marine, Refinery & Power Generation Industries

Our Hastelloy C22 plates are trusted globally in projects where material failure is unacceptable:

  • Chemical & Petrochemical Plants – scrubbers, reactors, chemical piping
  • Marine & Offshore – desalination units, seawater handling, offshore rigs
  • Oil & Gas Refineries – sour gas service, reactors, pressure vessels
  • Power Generation – FGD systems, heat exchangers, boilers
  • EPC Shutdowns – urgent replacement supply with global certifications

Wherever aggressive corrosion or extreme temperatures threaten performance, Hastelloy C22 plates offer durability, compliance, and confidence.
