Studs and Nuts
High-Strength Fasteners
Stud bolts are high-strength fasteners used in flanged systems and are one of the most critical components of the connection.
They are manufactured in different alloys according to the operating temperature, pressure and environmental conditions, ensuring safe and long-lasting use.
ASTM A193 Gr. B7
This is the most commonly used alloy steel stud type for high-pressure and high-temperature applications.
✔ High strength
✔ General industrial use
✔ Widely used in the oil, gas, and energy sectors
ASTM A193 Gr. B7M
These studs are manufactured with low hardness and are used especially in NACE and sour gas (H₂S) environments.
✔ Corrosion resistance
✔ Reduces cracking risk with low hardness
✔ Chemical and refinery applications
ASTM A320 Gr. L7 / L7M
This stud type is developed for low-temperature and cryogenic applications.
✔ Low temperature resistance
✔ High impact resistance
✔ LNG and cryogenic systems
ASTM A193 Gr. B16
These are special alloy steel studs for systems operating at very high temperatures.
✔ High heat resistance
✔ Ideal for steam lines
✔ Heavy industry applications
Stainless Steel Studs (B8 / B8M)
Corrosion-resistant stud solutions made of stainless steel.
✔ 304 / 316 grade options
✔ Suitable for chemical and marine environments
✔ Long service life
