ASTM A193 B7 All Thread Rods with Plain Finish

ASTM A193 B7 All Thread Rods – Plain Finish

High-Strength Alloy Steel for Pressure, Heat, and Structural Applications

ASTM A193 B7 all thread rods with a plain finish are engineered for demanding industrial environments, offering superior strength, temperature resistance, and reliability. Manufactured from heat-treated chromium-molybdenum alloy steel, these threaded rods are ideal for applications involving pressure vessels, flanged connections, and high-temperature systems.

What Is ASTM A193 B7?

ASTM A193 B7 specifies the standards for high-tensile alloy steel fasteners, including all thread rods, intended for use in high-pressure and high-temperature service conditions. The B7 designation indicates a quenched and tempered chromium-moly steel that offers excellent mechanical performance and durability under load.

These rods are fully threaded for versatile use in tensioning, anchoring, and structural bolting, and are commonly used in refineries, power plants, petrochemical facilities, and structural steel connections.

Plain Finish: Versatile and Customizable

The plain (uncoated) finish is ideal for:

• Indoor use in dry environments

• Applications requiring precise torque control

• Post-fabrication coatings like galvanizing or painting

This finish allows for flexibility in environments where corrosion resistance can be added or is not a concern.

Common Sizes and Applications

Available in standard diameters from 1/4" to 2" and lengths up to 12 feet, A193 B7 all thread rods are frequently used in:

• Flanged piping systems and pressure-rated bolted joints

• Structural steel frameworks

• High-temperature and high-stress environments

Engineered for Strength and Stability

For critical bolting applications where strength, heat resistance, and performance matter most, ASTM A193 B7 all thread rods with plain finish deliver dependable results in the most challenging conditions.
