What Are ASTM B575 Hastelloy C22 Sheets and Why Are They Trusted in Critical Industries?
Hastelloy C22 is a nickel-chromium-molybdenum alloy known for its ability to resist both oxidizing and reducing environments. Unlike stainless steel, which can fail in mixed chemical exposures, C22 sheets provide durable, long-term performance.
- Superior Corrosion Resistance – seawater, chlorides, chemical acids
- Thermal Stability – consistent strength under heat and acidic vapors
- Versatile Applications – used in refineries, chemical reactors, marine desalination & power plants
- Compliance-Ready – meets ASTM B575 / ASME SB575 standards
For industries where failure is not an option, Hastelloy C22 sheets remain the preferred choice.
Procurement Challenges Buyers Face When Sourcing Hastelloy C22 Sheets
Many EPC buyers face the same risks:
- Receiving substandard or wrong grades labeled as C22
- Missing NACE, PED, EN 10204 documentation during audits
- Transit damage due to poor packaging & handling
- Overpriced quotations with hidden charges for CIF/FOB delivery
- Late shipments delaying shutdown or commissioning schedules
With Navgraha Steels INC, these issues don’t exist. We guarantee:
- Certified Supply – ASTM, PED, NACE, IBR approvals
- Seaworthy Export Packaging – rust-proof wrapping, edge guards, wooden pallets
- On-Time Dispatch – from ready Mumbai stock & mill allocations
- Fair Pricing – transparent quotes for local & global buyers
- Audit-Ready Documentation – EN 10204 MTCs, TPI reports (SGS, Lloyd’s, TUV, BV)
