ASTM A193 Grade B7 is a standard specification for high tensile alloy steel bolting material for use in high temperature or high-pressure service and other special purpose applications. It covers material specification for bolting used in pressure vessel service, valves, flanges and fittings. ASTM A193 defines both SI (Metric) and inch-pound units.
Grade B7 is a heat-treated chromium-molybdenum (Cr-Mo) alloy steel with minimum tensile strength requirement of 125 ksi, yield 105 ksi, and maximum hardness of 35HRC. Boltport uses Alloy Steel AISI 4140 bar stock or forging stock to produce B7 headed and non-headed bolts. A193 Grade B7 is the most commonly used Bolt specification coupled with A194 Grade 2H Nuts for Bolting Carbon Steel pipeline. A193 B7 bolting is available in metric sizes from M6 to M180 and imperial sizes from 1/4 to 7 inches, in diameter.
Boltport is a manufacturer and supplier of A193 Grade B7 fasteners in form of Stud Bolts (Studs), Hex Bolts, Socket Head Cap Screws, Threaded Rods, Heavy Hex Bolts, Hex Screws, Double End Studs, Eye Bolts, Galvanized Hex Bolts, Anchor Bolts, etc.
