ASTM A193 B7 Bolt

Grade A193 Flange Head Bolt, ASTM A193 B7 Hex Head Bolt, ASME SA193 Grade B7 U Bolt, AISI Grade B7 Allen Bolt, B7 Grade Stud Bolt.

The bolts have chromium molybdenum and are made of steel that has been heating treated, as stated in the ASTM A193 B7 Metric Bolts specification. Chromium and molybdenum produce the bulk of the bolts, ASTM A193 Grade B7, the principal alloying components. The quenching and tempering processes, both involving heat, are used in the production of these Grade B7 A193 Allen Bolts. Heat treatment of the A193 B7 Bolts Content helps to develop the mechanical attributes the client want. For instance, the tensile properties of the Gr B7 SA193 Stud Bolt are enhanced after heating treatment.

In general terms, the ASME SA193 Grade B7 Hex bolts are offered with a finish described as “metal surfaces.” However, if the customer chooses, the A193 B7 Anchor bolt can be hot-dip galvanized, zinc plated, coated with Xylan or PTFE, or zinc studded.  The ASTM A193 B7 Threaded Rod benefits from having its corrosion resistance enhanced by a coating applied. Typical applications for these ASTM B7 Grade ASME SA193 Half threaded Stud bolts include fastening materials subjected to medium to extreme temperatures. These bolts can be air quenched at temperatures ranging from -40 degrees Fahrenheit to 900 degrees Fahrenheit, and they are liquid-quenched at temperatures between 50 and 900 degrees Fahrenheit.
