Product Description:
2.4867 high-temperature alloy (NiFe20Cr15, NiCr6015) is a nickel
based heat-resistant alloy under the German DIN standard. It has
become a core material in the fields of energy, chemical
engineering, aerospace, etc. due to its excellent high-temperature
strength, oxidation resistance, and corrosion resistance. The
following provides a detailed analysis of material characteristics,
application scenarios, and key process points:
1. Chemical Composition and Microstructure Design
The alloy is based on nickel (59.0-65.0%) and achieves performance
balance by precisely adjusting the ratio of chromium (14.0-19.0%)
and iron (19.0-25.0%). Chromium element forms a dense Cr ₂ O ∝
oxide film, endowing the material with sustained oxidation
resistance below 1200 ℃; The addition of iron reduces material
costs and improves thermal processing performance. The
strengthening effect of silicon (0.50-2.00%) is particularly
critical, as it segregates at grain boundaries to form Ni Ⅲ Si
phase, significantly enhancing high-temperature creep resistance.
The carbon content is limited to ≤ 0.15% to avoid brittleness
caused by carbide precipitation, while impurities such as sulfur
and phosphorus are strictly controlled (S ≤ 0.020%, P ≤ 0.025%) to
ensure welding performance.
2. Core performance advantages
1.Extreme environmental stability
In scenarios such as gas turbine combustion chambers, 2.4867 alloy
can maintain its σ ₀ at 980 ℃ during long-term operation ₂ ≥
180MPa, oxidation rate<0.1mm/1000h. Compared to similar
materials Inconel 600 (2.4816), its sulfur resistance has been
improved by 30%, making it particularly suitable for
sulfur-containing fuel environments.
2. Multi medium corrosion resistance
Experimental data shows that the corrosion rate in a 60% NaOH
boiling solution is less than 0.05mm/a, which is better than the
0.5mm/a of 316L stainless steel; The temperature tolerance of
molten salts (such as Na ₂ SO ₄ - V ₂ O ₅) reaches 900 ℃, making it
the preferred choice for heat exchange tubes in garbage
incinerators.
3. Process adaptability
The hot processing window is 900-1180 ℃, and the narrow manganese
content (≤ 2.00%) is controlled to avoid the risk of σ phase
precipitation. After solution treatment at 1150 ℃, the grain size
of cold-rolled materials can be controlled at ASTM grades 5-7, with
an elongation rate greater than 35%.

This product is an Electric Resistance Wire , also known as an Electrical Conductive Filament , Metallic Conductivity String , or electric heating wire .
Applications:
1. Aircraft engine components
Used for non rotating parts such as turbine sealing rings and
combustion chamber liners, the material purity is ensured through
vacuum induction melting+electroslag remelting (VIM+ESR) process,
with a fatigue life of 10 cycles (650 ℃/300MPa).
2. Chemical reactor
In the PTA oxidation reactor, the 2.4867 alloy lining can resist
pitting corrosion by acetic acid bromide ions and has a designed
lifespan of 15 years. A certain project uses 6mm thick plate to
manufacture the mixer, which reduces weight by 20% compared to
traditional Hastelloy C276.
3. Nuclear energy field
As an intermediate heat exchanger material for sodium cooled fast
reactors, it exhibits excellent performance in a 550 ℃ liquid
sodium environment, with a neutron absorption cross-section 40%
lower than that of 304 stainless steel.
