ASTM A193 B7 vs Grade 8 Fasteners

ASTM A193 B7 Fasteners

Due to its outstanding heat resistance and tensile strength, B7 steel is in high demand for applications that require high temperatures; as an ASTM A193 B7 steel, it is alloyed with chromium and molybdenum. B7’s strength is achieved by quenching and tempering it at 1200 degrees F. It is utilized in high-temperature and high-pressure applications, such as industries and vocations that need high temperatures and pressures. ASTM A193 Alloy Steel B7 Fasteners are often used in pressure vessels and valves in the oil and gas sector, as well as in chemical and petroleum facilities and pipe flange connections.

One of the strongest threaded rod materials available from AATP, B7 is available in lengths ranging from 6 to 12 feet. Corrosion resistance can be improved by using finishes like as yellow zinc, black oxide, and hot-dip galvanizing.

Grade 8 Fasteners

Made of Grade 8 (SAE J429) steel, these fasteners have a minimum tensile strength of 150 ksi, which is higher than many other steel grades. It is also quenched and tempered at 800 degrees Fahrenheit, which contributes to its strength.

The higher tensile and yield strength of these ASTM A193 Alloy Steel Grade B8 Fasteners make them a good choice for use in applications that are subject to extra stress or pressure.

Alloy Steel Threaded Products (AATP) is now offering dual certification to ASTM A354 BD and SAE J429 Grade 8, as well as Grade 8 Plated in lengths up to and including 8″ in length.

Additionally, AATP will be offering full-lengths in plain finish. This updated offering makes it possible for our customers to standardize on one supplier for their full requirements.

Grade 8 fasteners are made of alloy steel and have been hardened to a higher strength than Grade 2 fasteners. These high-strength bolts are often utilized in applications with standard temperature and pressure levels.
