What are the creep rupture strength and creep resistance data for Incoloy 901 fasteners at 650°C?
Incoloy 901 Hex Bolt (also known as GH901, Nimonic 901) is a nickel-iron-based precipitation-hardening superalloy widely used for high-temperature fastener applications up to 650°C. According to existing authoritative data, the creep rupture strength and creep performance data for Incoloy 901 Hex Bolt at 650°C are as follows:
Incoloy 901 Hex Bolt (also known as GH901, Nimonic 901) is a nickel-iron-based precipitation-hardening superalloy widely used for high-temperature fastener applications up to 650°C. According to existing authoritative data, the creep rupture strength and creep performance data for Incoloy 901 Hex Bolt at 650°C are as follows:
1. Creep Rupture Strength
600°C / 1000 hours: ≥ 230 MPa
Although the comprehensive material introduction for GH901 precipitation-hardening wrought superalloy does not directly list the precise value for 650°C/1000h, combining its high-temperature mechanical property trends and empirical data from engineering manuals, the creep rupture strength of Incoloy 901 Hex Bolt at 650°C/1000h typically falls within the range of 180–210 MPa.
600°C / 1000 hours: ≥ 230 MPa
Although the comprehensive material introduction for GH901 precipitation-hardening wrought superalloy does not directly list the precise value for 650°C/1000h, combining its high-temperature mechanical property trends and empirical data from engineering manuals, the creep rupture strength of Incoloy 901 Hex Bolt at 650°C/1000h typically falls within the range of 180–210 MPa.
In aero-engine fastener standards (e.g., ASTM A453 Grade 660, which has a composition similar to GH901), the minimum required creep rupture strength for Incoloy 901 Hex Bolt at 650°C is generally not less than 170 MPa (1000h).
2. Creep Resistance (Creep Performance)
Under conditions of 550°C / 100h / 588 MPa:
Total creep strain εt ≈ 0.318% – 0.385%
Plastic creep strain εtp ≈ 0.016% – 0.067%
Under conditions of 550°C / 100h / 588 MPa:
Total creep strain εt ≈ 0.318% – 0.385%
Plastic creep strain εtp ≈ 0.016% – 0.067%
Under conditions of 750°C / 100h / 186 MPa:
Total creep strain εt ≈ 0.1395% – 0.1525%
Note: Although a complete creep curve at 650°C is not provided, it can be inferred that Incoloy 901 Hex Bolt, under conditions of 650°C, 100–1000h, and a stress of approximately 200 MPa, typically exhibits a total creep strain controlled to <0.5%, demonstrating excellent creep resistance.

Furthermore, the data explicitly states that the creep resistance of Incoloy 901 Hex Bolt is more than 5 times superior to that of 304 stainless steel, further substantiating its engineering-useful creep stability at 650°C.
Summary
The creep rupture strength of Incoloy 901 Hex Bolt under conditions of 650°C and 1000 hours is approximately 180–210 MPa, and it exhibits a low creep rate with total strain <0.5% (under typical loads).
The creep rupture strength of Incoloy 901 Hex Bolt under conditions of 650°C and 1000 hours is approximately 180–210 MPa, and it exhibits a low creep rate with total strain <0.5% (under typical loads).
⚠️ In practical engineering applications, it is recommended to consult material test reports or conduct creep rupture/creep tests based on the specific heat treatment condition (solution + double aging), product form, and certification standards (e.g., AMS 5712, ASTM A453 Gr.660) of the Incoloy 901 Hex Bolt.
