Mechanical Performance
The Grade A, 1-inch standard screw demonstrates outstanding strength characteristics. With a minimum tensile strength of 900 MPa at room temperature and 600 MPa at 600°C, it substantially outperforms conventional stainless steel alternatives. The yield strength reaches 550 MPa at ambient conditions, maintaining 400 MPa at 600°C and 300 MPa even at 700°C. Hardness is optimally controlled at ≤35 HRC, balancing strength with ductility to prevent brittle failure during installation.
The fastener exhibits exceptional fatigue resistance, achieving ≥300 MPa at 10⁷ cycles and ≥500 MPa at 10⁵ cycles, ensuring long-term reliability under cyclic loading conditions encountered in rotating equipment and vibration-prone environments.
