Product Description

ASTM A193 Grade B7 Threaded Steel Bar

ASTM A193 B7 threaded steel bar or threaded steel rods are used to produce steel bolts which meet numerous specifications and material design properties. There are full Steel Threaded Rod or part Steel Threaded Bar. B7 alloy steel is a high temperature grade of A-193. B7 steel is also a chrome molybdenum steel with a minimum tensile strength of 125ksi, B7 grade bolts can be used in a variety of extreme conditions.

We can also produce high strength a193 gr b7 studs, A193 b7 studs are made of chrome molybdenum steel and heat treated to increase strength and reliability, they are also used in a wide range of industries, they can be used in various chemical, Applications in construction and oil fields. More specifically, B7 grade bolts can be used to improve the following types of applications: fittings, valves, pressure vessels, flanges, Threaded Rods, and more.
