Description

ASTM B407/ B409 N08811 800HT Seamless Pipe High Temperature Corrosion Resistant For Heat Exchange

Manufacturing qualified pipes conforming to B407 from qualified materials that meet B409 involves additional and specific requirements for the manufacturing, inspection, and performance of specific product forms.

Complementary, not conflicting: The B407 standard itself does not repeat all chemical composition details; it typically directly references or requires that "the material shall conform to the latest version of B409." Together, they constitute a complete quality process from alloy materials to pipe products.

Pipes made from this material, due to its special "cold-drawn" state and subsequent heat treatment, exhibit excellent resistance to high-temperature creep, rupture, and oxidation.

Chemical Composition Requirements (Weight %)
Element Requirement (ASTM A407) Typical Value / Comment
Nickel (Ni) 30.0 - 34.0 Balances the structure and provides corrosion resistance.
Chromium (Cr) 19.0 - 23.0 Provides oxidation and high-temperature corrosion resistance.
Iron (Fe) 39.5 min Balance.
Carbon (C) 0.05 - 0.10 Critical for high-temperature strength (controlled for 800H grade).
Manganese (Mn) 1.50 max -
Silicon (Si) 1.00 max -
Sulfur (S) 0.015 max -
Copper (Cu) 0.75 max -
Aluminum (Al) 0.15 - 0.60 Combined with Ti for strengthening.
Titanium (Ti) 0.15 - 0.60 Combined with Al for strengthening.
Al + Ti 0.85 - 1.20 Ensures adequate age-hardening potential.

Mechanical Properties
Property Requirement (ASTM A407) Notes / Condition
Tensile Strength ≥ 450 MPa (65 ksi) -
Yield Strength (0.2% Offset) ≥ 170 MPa (25 ksi) -
Elongation in 2 inches (50.8 mm) ≥ 30% For longitudinal strip specimens from the tube.
Grain Size ASTM No. 5 or coarser This is a critical requirement. The coarse grain structure is specifically developed to provide superior creep and rupture strength at elevated temperatures.

Applications:

Petrochemical & Steam Cracking
Chemical & Petrochemical Processing
Heat Treatment & Industrial Furnaces
Superheater and reheater tubes in advanced biomass/waste-to-energy plants, heat exchangers in gas turbine exhaust systems.
Nuclear Power Heat exchanger tubing, steam generator tubing, and core components
