B8c Allen Cap Screw

Like those specifications that cover the use of components in high temperature and elevated pressure, specification ASTM A193, makes room for some guidelines. From the instructions pertaining to their cooling to their chemistry, the conformance of the ASTM A193 B8C Bolts to said specification is a must. This specification covers Grade B8C, which in turn can be further divided into class 1 and class 2.
An austenitic stainless steel class, the ASME SA193 Grade B8C Bolts could be either heat-treated or work-hardened or the fasteners could be processed by both techniques. The classification of grade B8C into class 1 and class 2, is strictly established on the basis of their tensile strength. While the Astm A193 B8c Class 1 Stud has been Carbide Solution Treated, those bolts which fall under class 2 are not only Carbide Solution Treated, but they are also strain hardened. Amongst other details discussed in the specification, properties such as the tensile strength as well as the hardness property of the SA 193 B8C Screw have been discussed here as well.
