ASTM A193 GRADE B7 FASTENERS

ASTM A193 Grade B7 Bolts is a standard material specification for chromium-molybdenum alloy steel fasteners for use in high tensile, high temperature and special purpose applications. Grade B7 is a heat-treated chromium-molybdenum alloy steel with minimum tensile requirement of 100 ksi, yield of 75 ksi and maximum hardness of 35 HRC. ASTM A193 specification covers requirements for chemical composition, mechanical properties, hardness, heat-treatment, recommended nuts-washers for Grade B7 fasteners. ASTM A193 Grade B7 Bolts is the most widely fastener specifications, commonly found in bolting or piping, pressure vessels, valves, flanges and fittings.

ASTM A193 Grade B7 Bolts bolts and strung studs are made from a chromium-molybdenum steel and are extinguished and tempered to build up the ideal mechanical properties. Level B7 is the most widely recognized level of A193 jolts utilized in development. B7 strung studs and short, headed jolts are promptly accessible in the commercial center. Review B7 jolts are normally utilized in pipe spine associations. These jolts are ordinarily purchased and sold in a plain, uncovered metal completion however are regularly hot-plunge stirred, zinc plated, Xylan covered, PTFE covered, or generally covered for consumption opposition. Note that covered jolts will be unable to withstand the high temperatures that uncoated B7 jolts can be exposed to.

ASTM A193 Grade B7 Bolts 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 and inch-pound units.
