Quantity
As a senior fastener engineer, I present the DIN Bolt Nut manufactured to strict dimensional and performance standards. This product complies with DIN, NF, and ANSI specifications, with a nominal size of M36 and lengths available from 30 mm up to 1000 mm. It is classified as Grade A, delivering a minimum tensile strength of 910 N/mm². The material, N07750 (Inconel X‑750), is a nickel‑based superalloy known for its exceptional resistance to corrosion and oxidation, making it suitable for demanding service conditions across aerospace, energy, and chemical processing sectors, as well as high‑temperature and high‑pressure systems.
High‑Temperature Microstructural Stability
The alloy’s austenitic matrix (≥70 % Ni) is reinforced by γ′ precipitates (Ni₃(Al,Ti)). This structure resists harmful phase transformations even during prolonged high‑temperature exposure. After 1,000 hours at 700 °C, no significant coarsening or redistribution of precipitates occurs, ensuring consistent performance over extended service life.

Mechanical Reliability at Elevated Temperatures
Through precipitation hardening, the DIN Bolt Nut retains outstanding yield strength—above 600 MPa at 650 °C—far exceeding that of conventional 304 stainless steel (≈200 MPa). Impact toughness remains above 50 J at 700 °C, preventing brittle failure. Creep resistance is equally impressive: under 200 MPa at 700 °C, creep‑rupture life exceeds 1,000 hours, compared to roughly 100 hours for 316 stainless steel under identical conditions.

Oxidation and Fatigue Performance
The high chromium content (14–17 %) promotes a dense Cr₂O₃ scale, limiting oxidation weight gain to just 0.1 mg/cm² after 1,000 hours in air at 815 °C. Fatigue life at 650 °C and 300 MPa stress amplitude surpasses 10⁶ cycles, markedly higher than that of 304 stainless steel (≈10⁵ cycles). These attributes make this fastener an ideal choice for extreme environments, where long‑term safety and reliability are non‑negotiable.
