Threaded Bar

Grade B7 all thread rod is manufactured from an alloy which includes chromium-molybdenum steel, quenched and tempered, for added strength and corrosion resistance.

Grade B7 all thread rod is manufactured from an alloy which includes chromium-molybdenum steel, quenched and tempered, for added strength and corrosion resistance.

Grade B7 fully threaded rods and studs provide high wear resistance, high temperature resistance, and high strength. Made of alloy steel that has been heat treated, they are typically used in high pressure applications, such as valves and pressure vessels in petroleum and chemical equipment.

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. Boltport uses Alloy Steel AISI 4140 bar stock or forging stock to produce B7 headed and non-headed bolts.
