Generally the ASTM A193 GRADE B7 Bolts have been coated to enhance, impart or improve the corrosion resistance properties of the SA193 B7 Bolt material. Although it is important to note that A193 B7 U-Bolt coated bolts might not be able to withstand the high temperatures as compared to the elevated temperatures the uncoated Washers for ASTM A193 Bolts can be subjected to. These ASTM A193 B7 Bolts & B7 Bolt Material are could also be available in either hot-dip galvanized, zinc plated, PTFE coated, or otherwise Xylan coated.

The ASTM A193 GRADE B7 Bolts specification covers both alloy steel and stainless steel bolting material for e.g. – the Bolt And Nut ASTM A193 Grade B7 Specification which are meant for equipment’s such as -  pressure vessels, valves, flanges, and fittings. According to the specifications, the A193 B7 Eye Bolt, B7 Anchor Bolts and other ASTM A193 B7 Material can be used for either or both high temperature or high pressure service. The  ASTM A193 Gr B7 Material could also be applied to other special purposes.


The A193 B7m Specification covers both alloy steel as well as stainless steel ASTM A193 Grade B7M Bolts meant for use in pressure vessels, valves, flanges, and fittings, According to the PDF of  A193 B7m Studs, the components produced from this specification could be used for either or both  high temperature or high pressure service, or the SA 193 Gr B7m Bolts could also be used in cases of other special purpose applications. Ferritic steels that fall under the ASTM A193 Grade B7m Bolts specification must be properly heat treated in such a manner that it best suits the high temperature features of each grade. Immediately after rolling or forging, the bolting ASTM A193 B7m Bolts material has to be allowed to cool to a temperature under the cooling transformation range. The chemical composition requirements for each of the A193 B7m Bolts has been presented in detail.

Ferritic steels that fall under the ASTM A193 B7 Hex Bolts need to be properly heat treated. The heat treatment given to the ASTM A193 B7 Heavy Hex Bolts in such a way that it best suits the high temperature characteristics or the A193 B7 Hex Head Bolt Material Properties of each grade. Immediately after rolling or forging, the bolting ASTM -A193 Gr B7 Hex Bolt Equivalent material must be allowed to be cooled to a temperature below the cooling transformation range of the ASTM A193 B7 Hex Bolt.  These ASTM A193 B7 Hex Bolts and Nuts are could also be available in either hot-dip galvanized, zinc plated, PTFE coated, or otherwise Xylan coated.

We manufacture ASTM A193 stud bolts in national coarse (UNC) thread pitches, mainly used in traditional applications. A193 Flange Stud Bolt have 8 threads per inch (“thread per inch”) for rod diameters above 1 inch. B7 Studs is the most common specification grade for stud bolts. The chemical composition ASTM A193 B7 Studs requirements for each alloy has been presented in detail in our website. The SA 193 B7 2H Stud Bolts should not contain an unspecified element for ordered grade to the extent that the ASTM A193 B7 Stud material conforms to the requirements of another grade for which that particular element is a specified element.

ASTM A193 B7 Threaded Rod, and threaded studs are manufactured from a chromium- molybdenum based steel. The SA 193 gr B7 Acme Rod has been quenched and tempered or heat treated. Heat treating the ASTM A193 Grb7 Metric Rod aids in the rods to develop the desired mechanical ASTM A193 Grade B7 Threaded Rod Properties such as good tensile strength. ASTM A193 Grade B7 Threaded Bar is the most common grade of the A193 specification bolts used in construction.
