ASTM A194 Grade 8M Nuts

The ASTM A194 specification covers various bolts like the ASTM A194 Grade 8M Nuts made from carbon steel, alloy steel, as well as stainless steel. While the ASTM A194 is a specification that broadly takes into consideration martensitic and austenitic stainless steel nuts, the SA194 Grade 8M Heavy Hex Nuts indicates that this is an austenitic grade alloy.

Grade 8M means the stainless steel used in the production of A194 Grade 8M Heavy Hex Nuts is austenitic alloy 316. Speaking of the classes, A194 Grade 8M Nut Material is classified into two subclasses i.e class 1 which is a carbide solution treated fastener. On the other hand, ASTM A194 Grade 8m Class 2 Nuts are not only carbide solution treated, but also strain hardened. The specified A194 Grade 8M Hex Nuts are intended for high pressure or/and high temperature applications. Bars from which these ASTM A194 Gr. 8M Strain Hardened Nut have been made are hot wrought.

The material, which in this case is marine grade stainless steel i.e. Asme Sa194 Grade 8m nut may be further processed. The processing of A194 Gr 8M Nuts is carried out by either a centerless grinding process or by a cold drawing process. Austenitic stainless steel grades, for e.g. grade 8M may be solution annealed or annealed as well as strain-hardened. The A194 Gr 8m Material needs to conform to the prescribed chemistry requirements in addition to undergoing tests such as hardness tests, proof of load tests, and cone proof load tests.
