    ASTM A193 is the standard specification for alloy-steel and stainless steel bolts used in high-temperature or high-pressure environments or other special-purpose applications.  ASTM A194 is the standard specification for carbon and alloy steel nuts for bolts used in equivalent high-pressure or high-temperature environments. ASTM A193 and A194 Stud boltt and nuts from Raaj Sagar Steels are available in a range of grades, including B7, B16 B8 and B8M to meet different design, service conditions, mechanical properties, and high temperature requirements. ASTM A194 also covers the American Association State Highway and Transportation Officials Standard AASHTO M-292.

    These bolts and nuts are designed, manufactured and tested to comply with the standards set by ASTM A193 and A194 for chemical composition, tensile and hardness properties and high temperature characteristics.

    • This Table is applicable to Never-Seize paste and Fel-Pro lubricant, K=0.16.
    • The above Table is applicable only for ASTM A320 Grade B8, Class 2 and A193 Grade B8, Class 2 Stud Bolts. These are 304 SS material.
    • The torque values are approved for spiral wound graphite and PTFE filled gaskets, graphite sheet gaskets GHE and GHR types, ring joint, double jacketed and Camprofile gaskets.
    • The Final Torque Value accounts for 10% bolt relaxation.
    • The yield strength for strain-hardened bolts varies with diameter. Torque values for bolts greater than 1.1/2 in. diameter are based on 30 ksi yield strength.
