These fasteners are popular for additional support and security in industrial applications. An ASTM A193 B7 threaded rod uses chromium-molybdenum steel and gets produced via hot or cold forging or machining from bar stock.
The manufacturing process of a stud bolt A193 B7 involves quenching and tempering as necessary heat treatments, performed at 1150°F. These procedures provide additional strength and corrosion resistance to SA 193 grade B7 studs.

These durable fasteners have good corrosion resistance and hardness (35HRC). Customers can also request special protective coating for ASTM A193 grade B7 studs based on their requirements. For example, zinc-nickel plating and anodising are standard options for enhanced durability.
SA 193 grade B7 studs can also undergo hot-dip galvanisation or other mechanically applied coatings specified by the buyer. Black oxide plating on B7 all thread can also safeguard against corrosion.
If you want ASTM A193 grade b7 threaded rod and double end stud for critical application, you can depend on us, we will complete your project need
An ASTM A193 Gr B7 stud bolt has extensive threading that can extend along its complete length. The minimum tensile rating is 860 Mpa; it has a yield strength of 720 Mpa.
Thus, customers can conveniently use an A193 B7 stud bolt for applications demanding greater robustness.
We recommend evaluating the following while picking a B7 all thread for your requirement:
- Impact toughness
- Ductility
- Exposure to environmental stressors like high-pressure
- Testing for tensile strength, hardness, and corrosion resistance (as stated in the MTC)
Exercising caution while picking a suitable ASTM A193 Gr B7 stud bolt will reduce risks of catastrophic failures and safety hazards to the personnel or the infrastructure.

Get here complete information of A193 B7 stud bolt and threaded studs including chemical composition and mechanical properties
An A193 B7 double end stud has threading of the same length at both ends and features an unthreaded region in the middle. The core advantage of A193 B7 studs is enhanced strength and security of bolting.
The composition of an A193 B7 double end stud includes chromium (0.80 to 1.10%), molybdenum (up to 0.25%), and phosphorus.
These fasteners also include silicon, sulfur, and carbon in trace amounts. Manganese is present in 0.75 to 1.00% and contributes to the tensile strength of the stud bolt A193 B7.
