ASTM B622 / ASME SB622 Alloy C276 / UNS N10276 / DIN 2.4819 Seamless Hastelloy Tube

YUHONG GROUP is specialized in manufacturing and supplying heat exchanger tube/boiler tube/condenser tube. Our products has exported more than 55 countries till now and won good reputation among the clients. ASME SB622 UNS N10276 Nickel Alloy Seamless Tube Hastelloy C276 Tube Heat Exchanger Tube is a seamless, nickel-base alloy tube made from UNS N10276, commonly known as Hastelloy C276 / Alloy C276, manufactured according to ASME SB622 (the ASME version of ASTM B622), and intended mainly for heat exchanger service.

In simple terms, it is a weldless Hastelloy C276 tube produced to the ASME SB622 specification for use in shell-and-tube heat exchangers, condensers, evaporators, and similar corrosion-resistant heat-transfer equipment.

Key Characteristics of Using Grade UNS N10276/ Hastelloy C276

Excellent resistance to oxidizing and reducing acids
Outstanding resistance to chlorides, seawater, brine, and hypochlorite
Resistant to pitting, crevice corrosion, and stress corrosion cracking
Good resistance to sulfuric acid, hydrochloric acid, phosphoric acid, acetic acid, formic acid
Good weldability using matching fillers such as ERNiCrMo-4 / ENiCrMo-4
Good high-temperature stability
Preferred for severe corrosion and pressure-tight heat exchanger service

Choose ASME SB622 UNS N10276 / Hastelloy C276 seamless heat exchanger tube when the service is too corrosive or too critical for stainless steel. Main situation:

When	Short reason
Strong acids: HCl, H₂SO₄, H₃PO₄, acetic, formic, mixed acids	C276 resists both oxidizing and reducing acids.
Chlorides, seawater, brine, hypochlorite	Excellent resistance to pitting, crevice corrosion, and SCC.
Chemical / petrochemical / pharmaceutical heat exchangers	Handles aggressive media where 316L, 904L, duplex, or 6Mo may fail.
High-pressure or critical heat exchanger service	Seamless tube avoids weld-seam weakness and leakage risk.
Code requires ASME SB622 / ASTM B622	Ensures pressure-code compliance and traceability.
High temperature + corrosive environment	Good high-temperature corrosion resistance and stability.
U-bent or severe bending heat exchanger tubes	Seamless C276 has good ductility and uniformity.
