ASTM B407 ASME SB407 N08811 Alloy Steel Tube for High Temperature

ASTM B407 / ASME SB407 N08811 Alloy Steel Tube is a high-performance nickel-based alloy tube that complies with ASTM B407 standard specifications. It is mainly composed of elements such as nickel (Ni), iron (Fe), and chromium (Cr), with a relatively high content of nickel, which provides excellent corrosion resistance and high-temperature oxidation resistance.

• Excellent corrosion resistance in various corrosive media
• Superior high-temperature stability and mechanical properties
• High yield strength and tensile strength
• Excellent processability for various cold and hot working processes

Preparation process: melting, casting, heat treatment (annealing between 1120~1170℃), cold processing

Processing precautions: Careful operation during cold rolling to avoid surface damage; requires acid washing and polishing after cold rolling

• VS N08800: Lower carbon content, no grain size requirements, lower high-temperature creep strength
• VS N08810: Similar performance, often considered equivalent in high-temperature applications
• VS Alloy 600/601/625: More cost-effective with comparable high-temperature strength
• VS Austenitic Stainless Steel: Superior strength and creep resistance at extremely high temperatures (>800°C)

• Petrochemical industry: Reactors, heat exchangers, piping systems
• Aerospace: Engine turbine blades, combustion chambers
• Electric power industry: High-temperature flue gas treatment, boiler components
• Chemical engineering: Corrosion-resistant equipment for harsh conditions
