According to the ASTM A193 B7m Bolts specification, the bolts are chromium molybdenum, heat treated steel. The primary alloying content of the ASTM A193 Grade B7 Bolts are chromium and molybdenum. These ASTM A193 B7 Metric Bolts are manufactured by quenching and tempering with heat. Treating the A193 B7 Bolts Material with heat helps to develop the desired mechanical properties for e.g. the tensile strength of the ASTM A193 B7 Hex Bolts is increased after heat treatment.
Table of Content
The standard ASTM A193 B7 Fasteners are typically available in a plain, bare metal finish. But if required by the buyer, the ASTM A193 Grade B7 Stud Bolts can be zinc plated, hot-dip galvanized, Xylan coated, PTFE coated. Coating the ASTM A193 B7 Fasteners aids in enhancing the corrosion resistance of the fasteners.This ASTM A193 Grade B7m Bolts are commonly used in fastening medium high temperature service materials. These bolts are liquid quenched between a range of 50 °F to 900 °F and they can be air quenched at temperatures ranging between - 40 °F to 900 °F.
The minimum yield and tensile strength requirements for the ASTM A193 Grade B7m Bolts are reduced as opposed to the B7 grade bolt.ASTM A193 B7 Heavy Hex Bolts are readily available in the marketplace. Hence the A193-B7 Stud Bolts are used in many applications due to their easy availability. ASTM A193 B7 Stud Bolts are commonly used in pipe flange connections and in construction.
