ASTM A193 Grade B16 is a standard material specification under ASTM A193, for alloy steel bolting material, for use in high tensile, high temperature and special purpose applications.
Grade B16 is a heat-treated chromium-molybdenum-vanadium (Cr-Mo-V) alloy steel with maximum tensile strength of 860 MPa, yield 725, and 35HRC hardness. ASTM A193 grade B16 is similar to grade B7 but the addition of vanadium enhances its strength holding capacity at high temperatures. Grade B16 is suitable for applications up-to 450°C (840°F). Fasteners produced under ASTN A193 Grade B16 standard are mainly used for power generation and allied sectors.
Grade B16 is specified for bolts, studs, stud bolts, threaded rods, screws, bar stock and similar parts, intended for use in bolting applications. Visit our A193-Grade-B16 microsite for specific details.
