ASTM A194 Grade 8C Heavy Hex Nuts
ASME SA 194 Gr 8C Hex Nuts
A194 Gr. 8C Washers
Table of Content
High temperature and high pressure applications call for heavy duty materials for the manufacture of sturdy, tough and long lasting fasteners. In addition to the material, a correct guiding system also increases the longevity of the product. Hence, many suppliers prefer ordering fasteners keeping regulatory specifications. In the case of high temperature and high pressure applications, manufacturers use specification ASTM A194.
Primarily materials like stainless steels or alloy steel or even carbon steels may be used to produce the ASTM A194 Grade 8C Heavy Hex Nuts. In stainless steels, the grades involved in the manufacture of these fasteners strictly belong to either martensitic or austenitic classes. Bars from which the ASTM A194 Grade 8C Hex Nuts have been produced are to be hot-wrought. Processing of these alloys is possible by employing techniques like centerless grinding or even by using cold drawing. Austenitic stainless steel ASTM A194 Grade 8C Washer is to be subjected to heat treatments in the form of either solution annealing or they may be annealed followed by strain-hardening.
Each material for ASTM A194 Grade 8C Nuts is required to adhere to the chemistry specifics prescribed in the specification. To check the conformance of the nuts to the requirements, the ASME SA 194 Gr 8C Nut is subjected to tests like Hardness tests, proof of load tests, as well as cone proof load tests
