ASTM A193 Grade B16 Bolts

Under the ASTM A193 specification, the standard fasteners covered include alloy steel and stainless steel bolts such as ASTM A193 B16 Hex Bolt. Typically the A193 B16 Heavy Hex Bolts produced using this specification are designed with the intention of being used in high temperature or/and high pressure environments. Apart from these conditions, the ASTM A193 gr b16 steel bolts may be used for other special purpose applications as well.

The astm a193 b16 chemical composition consists of alloying elements such as chromium, vanadium and molybdenum. The chemistry of alloy steel astm a193 gr b16 material is well suited for high strength industrial applications. Therefore, the stud bolt ASTM A193 gr b16 is commonly used in the construction of power generation turbines in high temperature high pressure applications.  The ASTM A193 grade b16 stud bolts are a heat treated alloy with its unique Chromium, Molybdenum and Vanadium containing chemistry. The specification of the ASTM A193 Grade B16 Bolts calls for minimum strength as well as maximum hardness levels. Considered to be most suitable for use at temperatures below 840°F, the ASTM A193 B16 Threaded Rod could be used in those conditions where the fasteners have been exposed to moderately high temperatures.

Although fasteners such as the astm a193 b16 nuts and bolts have similar strength requirements as Grade B7, the content of vanadium in conjunction with higher tempering temperature on the b16 header bolts is what helps the fasteners retain their molecular structure. The sa193 b16 Studs also retain their strength under higher ambient temperatures as compared to Grade B7. Unlike other stainless steel alloy grades within the ASTM specification  A193, Grade b16 transmission bolts have no corrosion resistance properties. However, this can be rectified by coated the surface of astm a193 b16 bolts.
