Alloy ASTM A193 Grade B16 is a bolting specification for high temperature service. It is a heat treated Chromium-Molybdenum-Vanadium steel. The specification calls for minimum strength and maximum hardness levels. It is considered to be most suitable for bolts used at ASTM A193 B7 heat treatment process ? - Metal and Jan 30, 2008 · The spec only requires a 35HRC maximum hardness. The material is 4140 alloy steel. The annealed hardness is currently 23 HRC. ASTM A193 requires that the tempering process be done at 100 degress below the heat treat temperature. For B7 that temperature is 1100F.
Jun 03, 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.
