Avesta 254 SMO with World Wide Shipping

Avesta Sheffield 254 SMO® fasteners, also known by its UNS S31254, are made of an austenitic stainless steel that has very high resistance to pitting and crevice corrosion due to its high molybdenum content. The metal was designed for the use in halide-containing environments such as seawater. 254 SMO also has good resistance to uniform corrosion and is superior to conventional stainless steels especially in acids containing halides.

The elevated levels of molybdenum in particular but also of chromium and nitrogen endow 254 SMO with extremely great resistance to pitting and crevice corrosion. The addition of copper provides increased resistance in certain acids. Due to its relatively high nickel content in addition with the high levels of chromium and molybdenum 254 SMO has excellent resistance to stress corrosion cracking.

Even highly alloyed stainless steels have limited applicability in environments which have halide ions, e.g. chloride, bromide and fluoride solutions. It is for this reason it has often been necessary to use such expensive materials such as nickel based alloys or titanium for these environments. Avesta 254 SMO was developed with a view of offering a less expensive alternative to the conventional pricier alloys.

Its high nitrogen content 254 SMO has higher mechanical strength than most other austenitic stainless steels. Similar to these, 254 SMO is characterized by high ductility and impact strength as well as good weldability. The high molybdenum content of 254 SMO can lead to an increased oxidation rate at annealing and as a consequence a rougher surface finish after pickling than standard stainless steels.

Due to its excellent anti-corrosive behaviors, many types of fasteners can be made from Avesta 254 SMO. Lightning Bolt has Avesta 254 SMO with World Wide Shipping and also has the capabilities to provide you with Avesta 254 SMO fasteners such as hex bolts, nuts, washers, studs, and special orders.
