ASTM A193 Grade B8M fasteners are stainless steel high-performance fasteners made of austenitic SS 316, which are to be used in environments with high temperature and corrosion. The reason behind the high resistance to chlorides, chemicals, and the marine atmosphere of these fasteners is because of molybdenum that is present in their composition. B8M fasteners are normally made in both Class 1 (solution annealed) and Class 2 (strain hardened) where the users can decide the level of ductility and mechanical strength based on the requirements of the application. The annealed condition is non-magnetic, and the material is very resistant to pitting corrosion; hence, it is suitable to use in demanding industrial environments.
These nuts are commonly applied in petrochemical facilities, offshore platforms, marine engineering, power stations and food processing machinery. ASTM A193 B8M fasteners are designed to be strong and stable in a large range of temperatures, both cryogenic service up to high operating temperatures. Their versatility in terms of durability, resistance to corrosion and long life span lowers the maintenance costs incurred and enhances safety in life threatening installations. Due to these characteristics, the B8M fasteners are relatively suitable in any case when the reliability and the ability to work in harsh conditions are needed.
