- Commodity name: ER25-35Nb
The weld joint maintains high strength and creep resistance at high temperatures of 600-1000℃, suitable for long-term service in high-temperature and high-pressure environments; excellent high-temperature oxidation resistance, able to resist oxidation corrosion from flue gas, steam and other media.
Product Performance
● High-Temperature Performance:
Welded joints maintain high strength and creep resistance at high temperatures (600-1000℃), suitable for long-term service in high-temperature and high-pressure environments.
Excellent high-temperature oxidation resistance, capable of resisting oxidation corrosion from flue gas, steam, and other media.
● Welding Performance:
Processes such as Gas Tungsten Arc Welding (GTAW) and Gas Metal Arc Welding (GMAW) can be used. The welding process has stable arc, good molten pool fluidity, and beautiful weld formation.
Low sensitivity to hot cracking, but welding heat input needs to be controlled to avoid coarse grain affecting toughness.
● Mechanical Properties (Typical Room Temperature Values):
Tensile Strength: ≥550 MPa
Elongation: ≥30%
High-temperature (800℃) Tensile Strength: ≥200 MPa, with good high-temperature toughness.

The company currently owns production equipment such as vacuum melting, electroslag remelting, forging and hot rolling (outsourced), solution treatment, machining, cold drawing, cold rolling (outsourced), and polishing. Our own laboratory can complete the testing of alloy chemical composition, mechanical properties, and flaw detection.
We can independently produce high-performance alloy materials such as nickel-based superalloys, cobalt-based superalloys, precision alloys, and special stainless steels. Products: forgings, billets, coils, bars, slabs/sheets, etc.
