Comprehensive Analysis of B7 High Strength Bolts

The B7 bolt is a high-strength heat-treated (quenched and tempered) bolt, which is named according to the B7 grade in the ASTM A193/A193M standard. This type of bolt is generally used in high temperature and high pressure environments, so it is widely used in petroleum, chemical industry, power station and other industries. B7 bolts are mainly made of chromium-molybdenum alloy steel and are usually used with A194 grade 2H heavy-duty hex nuts. Its surface treatment is diverse and can be galvanized, black plated, oiled, hot-dip galvanized, etc. as needed to adapt to different working environments.

Performance characteristics of B7 bolts. B7 bolts have the following significant performance characteristics:

1. High temperature performance

Due to its special material, B7 bolts can work normally at temperatures up to 450°C and maintain good mechanical properties. This makes it ideal for fastening high-temperature pipelines and equipment.

2. Good strength and toughness

B7 bolts have high tensile strength and yield strength and are not easy to break even under large loads and impacts.

3. Corrosion resistance

Through different surface treatments, B7 bolts can obtain better corrosion resistance and can adapt to a variety of corrosive environments.

4. Ease of processing

Although the B7 bolt has a higher hardness, it can still be processed such as cutting and welding, maintaining good processing performance.

Application scope of B7 bolts

The application fields of B7 bolts are very wide, and they can be mainly seen in the following industries:

Petrochemical industry: In the connection and fixation of petroleum refining and chemical equipment, B7 bolts can withstand high pressure and high temperature, ensuring the safe and stable operation of the equipment.

Power generation industry: Boilers, steam turbines and other equipment in power plants operate under extreme conditions, and B7 bolts are suitable for fastening these components.

Construction industry: Some special building structures, such as steel structure bridges and high-rise buildings, need to withstand greater stress, so B7 bolts are commonly used to fasten key connecting components.

Marine engineering: Marine engineering such as offshore oil platforms require fasteners to have excellent anti-corrosion properties and the ability to resist the influence of marine climate. B7 bolts can meet these needs with their special materials and surface treatments.

Heavy machinery: In the manufacturing of heavy vehicles and large mechanical equipment, high-strength fasteners are often needed to verify the safety of the structure, so B7 bolts are widely used.
