SMO 254 Fasteners
SMO 254 Fasteners are the austenitic stainless steel fasteners that consider the high level of molybdenum, nitrogen, and along with low carbon content. The fasteners exhibit superior resistance to crevice, stress corrosion cracking and pitting corrosion. Furthermore, these are also resistance to fatigue and uniform corrosion. These grade of fasteners are significantly stronger than other steel alloys. These fasteners feature impact strength and high ductility. These are fasteners used in high chlorides atmosphere such as seawater and in brackish water. The fastener ensures superior toughness and high strength at cryogenic temperatures. In addition to it demonstrate good mechanical properties at both moderate and high-temperature surroundings.

The fasteners are forged upset at 982-1149 degree C whereas to attain maximum corrosion resistant properties post process annealing is performed. While the cold working is achieved by traditional methods. Therefore these cold working ensures good hardenability.

What are SMO 254 Fasteners?

SMO 254 fasteners are a type of high corrosion-resistant stainless steel fastener. They are one of the most widely used and versatile materials for fastener applications, combining superior strength with good corrosion resistance. As a result, these fasteners provide longer life in corrosive environments, including marine and industrial applications, as well as many automotive industries. SMO 254 fasteners are thicker than standard grades 18-8, providing superior strength and durability compared to other steel grades. Furthermore, SMO 254 provides superior resistance against general pitting caused by oxidizing acids and chloride stress corrosion cracking when exposed to temperatures up to 593°C (1100°F). With all these features combined, SMO 254 fasteners offer the perfect balance of performance and value for any application.

What are 254 SMO material bolts?

254 SMO material bolts are highly reliable and resilient components used in industrial applications. These specialized bolts are made from an austenitic stainless steel alloy known as 254SMo (or 6Mo) to create a highly resistant product to corrosion and oxidation. Their robust nature makes them the ideal choice for wet or highly salty environments, offering much more excellent durability even in the face of intense wear and tear.
