Is Grade 5 the same as B7?
B7. This chromium molybdenum steel has similar strength to SAE grade 5 fasteners, however, it is specifically used in high temperature and pressure applications. This grade is for fittings, flanges, valves, and pressure vessels. It is also used as threaded rod in concrete and epoxy.
What grade is B7 steel?
ASTM A193 B7 is a chrome-moly steel with strength similar to Grade 5 properties and is commonly used in high temperature and pressure applications.
Is 4140 the same as B7?
How much weight can a 1/4 threaded rod hold?

What is the tensile strength of 5/8 all thread?
. 60,000 psi
A: The Everbilt 5/8 in. -11 tpi x 12 in. Zinc-Plated Threaded Rod is made to A307 Grade A and the tensile strength is min. 60,000 psi.
How much weight can a 3/8 bolt hold?
A 3/8-inch bolt of this type is rated to 7,000 pounds in 6,000 psi concrete (basically granite) and 4,000 pounds in 2,000 psi concrete (hard sandstone). This is roughly the breaking strength range of carabiners and much higher than any rope’s maximum possible impact force.
How strong is B7?
Grade B7 is a heat-treated chromium-molybdenum low-alloy steel with minimum tensile strength requirement of 125 ksi (860 Mpa), yield 105 ksi (720 Mpa), and maximum hardness of 35HRC.
