ASTM A193 B7 Bolts


What is ASTM A193 B7

ASTM A193 Grade B7 specifies high tensile alloy steel bolting material for high temperature or high-pressure duty and other special-purpose applications. It is a standard specification that defines the typical chemical composition, mechanical qualities, hardness requirements, preferable heat treatment, product labelling, certification, and other criteria for pressure vessel fastening, valves, flanges, and fittings.

ASTM A193 Grade B7 Bolts and Nuts are typically used for attaching medium to high-temperature service materials. These ASTM A193 B7 bolts may be liquid quenched at temperatures ranging from 50 °F to 900 °F and air quenched at temperatures ranging from -40 °F to 900 °F.


A193 B7 Threaded Rod vs. Studs

Standard ASTM A193 B7 Fasteners are usually supplied in a bare metal finish. However, the ASME SA A193 B7 Studs can be zinc plated, hot-dip galvanised, Xylan coated, or PTFE coated. Coating the ASTM A193 B7 Fasteners helps to improve their corrosion resistance.


A193 B7 Hex Bolts vs. UNS S34700 Heavy Hex Bolts

ASTM A193 Grade B7 threaded rods and studs provide excellent resistance capabilities that include high-temperature resistance, and tensile strength. In addition, they are also composed of heat-treated alloy steel and are used largely in high-pressure applications.

A193 B7 Hex Bolts are ideal for industrial and structural bolting applications with high-temperature or high-pressure service environments. On the other hand, stainless steel UNS S34700 Heavy Hex Bolts provide high oxidation resistance and superior strength at temperatures up to 2100 degrees Fahrenheit.

Grade B7 Flat Washers are frequently used in food, chemical, electrical, generator, shaft, cement, gas, and power projects. Our clients get these B7 washers in various thicknesses, sizes, weights, and grades.
