ASTM A193 B7 vs Grade 8 Fasteners - Rolled Threads

May 05, 2021 · ASTM A193 B7 is a chrome-moly steel with strength similar to Grade 5 properties and is commonly used in high temperature and pressure applications. Common uses for grade 8 bolts are military, heavy manufacturing and other demanding mechanical applications where high stress and strong load bearing pressures are a major factor. ASTM A193 Grade B7 - Boltport FastenersASTM A193 Grade B7. ASTM A193 Grade B7 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

ASTM A193 Grade B7 Specification - Boltport Fasteners

Grade B7 is a heat-treated chromium-molybdenum low-alloy steel with minimum tensile strength requirement of 125 ksi (860 Mpa), yield 105 ksi (720 Mpa), and maximum hardness of 35HRC. Boltport uses Alloy Steel AISI 4140 bar stock or forging stock to produce B7 headed and non-headed bolts.
