Characteristics and Applications of the Customized Thread Rod
The Customized Thread Rod is a high-strength alloy steel bolt widely used in high-temperature, high-pressure, and high-stress environments. To ensure its performance and reliability in different application environments, we provide some recommendations for its selection:
The Customized Thread Rod is a high-strength alloy steel bolt widely used in high-temperature, high-pressure, and high-stress environments. To ensure its performance and reliability in different application environments, we provide some recommendations for its selection:
1. High-Temperature Environments
The Customized Thread Rod is suitable for a temperature range of -29°C to 450°C. In high-temperature environments, the mechanical properties of B7 material will change, so selection should be based on the actual temperature.
The Customized Thread Rod is suitable for a temperature range of -29°C to 450°C. In high-temperature environments, the mechanical properties of B7 material will change, so selection should be based on the actual temperature.
Data Reference:
At 300°C, the yield strength of the Customized Thread Rod is about 90% of that at room temperature.
At 300°C, the yield strength of the Customized Thread Rod is about 90% of that at room temperature.
At 450°C, the yield strength drops to 75% of that at room temperature.
Above 500°C, B7 material may experience creep and relaxation, and higher-grade materials (such as ASTM A193 B16) should be selected.
Above 500°C, B7 material may experience creep and relaxation, and higher-grade materials (such as ASTM A193 B16) should be selected.
Selection Recommendations:
If the working temperature is close to 450°C, it is recommended to choose a higher specification of the Customized Thread Rod or increase the safety factor.
If the working temperature is close to 450°C, it is recommended to choose a higher specification of the Customized Thread Rod or increase the safety factor.
In environments with significant temperature fluctuations, consider the material's thermal expansion coefficient and select an appropriate preload.
Regularly check the preload of the Customized Thread Rod to prevent connection failure due to high-temperature relaxation.

2. High-Pressure Environments
The Customized Thread Rod is suitable for a pressure range determined by design loads. In high-pressure environments, the high-strength characteristics of B7 threaded rods make them an ideal choice, but selection should be based on the actual pressure.

Data Reference:
| Thread Rod Size | Load Capacity (kN) | Remarks |
| M8 | 30 | Suitable for small equipment or low-load applications |
| M10 | 50 | Suitable for medium-load applications |
| M12 | 70 | Suitable for general high-pressure environments |
| M16 | 120 | Suitable for higher-load applications |
| M20 | 180 | Suitable for high-pressure equipment or heavy-duty connections |
| M24 | 280 | Suitable for large high-pressure equipment or high-load applications |
| M30 | 400 | Suitable for ultra-high pressure or heavy-duty equipment |
| M36 | 560 | Suitable for ultra-high load or extra-large equipment |
Load Capacity Calculation:
Load capacity is based on the minimum tensile strength of B7 material (860 MPa) and the cross-sectional area of the threaded rod.
Load capacity is based on the minimum tensile strength of B7 material (860 MPa) and the cross-sectional area of the threaded rod.
Formula: Load Capacity = Tensile Strength × Cross-Sectional Area.
Safety Factor:
In high-pressure environments, a safety factor of 1.5-2.0 is recommended.
In high-pressure environments, a safety factor of 1.5-2.0 is recommended.
Actual Design Load = Load Capacity ÷ Safety Factor.
The diameter and quantity of the Customized Thread Rod required should be calculated based on the design load to ensure the safety factor.
Use a torque wrench or hydraulic tensioner to precisely control the preload, avoiding overload or loosening.
Regularly check the stress state of the bolts to ensure the Customized Thread Rod is within a safe range.
