A193 Grade B7 Thread Rods are high-strength fasteners designed for applications requiring tension or compression. They are commonly used in construction projects, oil and gas pipelines, and industrial machinery assembly. The "B7" designation indicates that the rods are made from chrome-molybdenum steel, which offers excellent strength and heat resistance.
Material Selection: Premium alloy steel or stainless steel is selected to meet ASTM standards.
Precision Cutting: Raw materials are cut to required lengths using advanced machinery.
Threading: High-precision threading machines ensure uniform and accurate threading across the rods.
Surface Treatment: Depending on the application, rods undergo galvanization, black oxide coating, or HDG for corrosion resistance.
Quality Control: Each rod is subjected to rigorous testing to ensure dimensional accuracy, tensile strength, and compliance with global standards.
Feature | B7 Thread Rod | B7M Thread Rod |
Material | Chrome-molybdenum steel | Chrome-molybdenum steel |
Tensile Strength | Higher | Slightly lower due to lower hardness |
Application | High-pressure and high-temperature use | Medium-pressure and corrosive environments |
Hardness | As per ASTM A193 | Lower hardness as per ASTM A193 |
Determine Application Requirements: Identify the environment, load-bearing capacity, and corrosion resistance needed.
Check Standards: Ensure the rod complies with relevant standards like ASTM.
Select Surface Finish: For outdoor use, choose galvanized or HDG finishes for added protection.
Consider Customization: Opt for custom lengths or finishes if standard options don’t meet your needs.
Can A193 Grade B7 Thread Rods Be Used in Corrosive Environments?
Yes, but it depends on the surface finish. Galvanized or HDG coatings provide excellent corrosion resistance, making these rods suitable for outdoor or humid environments. For extreme conditions, consider using stainless steel grades like B8 or B8M.
