Product information

Grade: GH4413
Steel Manufacturer: Haynes; SMC; ATI; VDM; Outokumpu; NYK; Jinri Tiefu, Fushun / Northeast Special Steel
GH4413 (GH413) is a Ni-Cr-based precipitation-hardening high-temperature alloy with excellent high-temperature strength, oxidation resistance, corrosion resistance, and microstructure stability. It is widely used in aerospace, energy, and chemical industries.
High-temperature properties
Below 850℃, the tensile strength can reach 700-900 MPa, the yield strength 400-600 MPa, and the elongation 20%-30%. After 10,000 hours of long-term aging, the microstructure remains stable, and no topological dense phase (TCP phase) precipitates occur. ‌
Oxidation and corrosion resistance
A dense protective chromium oxide layer spontaneously forms on the surface, effectively blocking the invasion of corrosive media such as oxygen and sulfides. In the static oxidation test at 900℃, the oxidation rate is less than 0.1 mg/(cm²·h), and the corrosion rate in a sulfur-containing atmosphere is 40% lower than that of traditional alloys. ‌
Mechanical properties
Through γ' phase strengthening (total Al+Ti 4.5%) and solution strengthening (W+Mo 11%), both strength and plasticity are balanced. The anti-warping performance is outstanding at 800℃-950℃ high temperatures, and the creep strain after 1000 hours is less than 1%. ‌
Application process
The standard heat treatment regime is: 1120℃ solution treatment + 1050℃ intermediate aging + 850℃ final aging. The hot processing temperature range is 1100-1150℃, and the deformation range is recommended to be 35%-50%. The final forging temperature should be ≥ 950℃ to avoid intergranular cracking. ‌

Product parameter

Chemical composition 
GH4413 is a nickel-based superalloy. Its main chemical composition includes 13.00 - 16.00% nickel (Ni), 2.40 - 2.90% chromium (Cr), 9% tungsten (W) and molybdenum (Mo), as well as trace amounts of titanium (Ti), aluminum (Al), iron (Fe), boron (B), and cerium (Ce). 

Chemical Composition Details
The chemical composition design of the GH4413 alloy aims to achieve high strength, creep resistance, and corrosion resistance under high-temperature conditions. The specific composition is as follows:
Base elements: Nickel (Ni): 13.00 - 16.00%, serving as the alloy base, providing high-temperature stability and corrosion resistance. 
Chromium (Cr): 2.40 - 2.90%, enhancing oxidation resistance and corrosion resistance. 
Strengthening elements: Tungsten (W) and molybdenum (Mo): 9% in total, enhancing high-temperature strength and creep resistance through solid solution strengthening. 
Aluminum (Al) and titanium (Ti): Total ≤ 0.04%, forming γ' phase (Ni₃Al/Ti) precipitation strengthening. 
Minor added elements: Boron (B) and cerium (Ce): Minor additions to optimize grain boundary strength and improve high-temperature microstructure stability. 

Performance Correlation
The combination of these components gives GH4413 the following characteristics:
High-temperature stability: No harmful phase precipitation during long-term aging (10,000 hours/800 - 900°C). 
Process adaptability: Performance can be optimized through vacuum melting and precise heat treatment.
