SMO 254 Fasteners

SMO 254 Fasteners

Fasteners that contain a high content of nickel or titanium in their alloy are usually very expensive. A suitable, cost-effective replacement for these applications is the SMO 254 Fasteners. This very high-end stainless steel alloy belongs to the austenitic class. The composition of the alloy gives it many properties that include resistance from different forms of corrosion and excellent workability.

SMO 254 Fasteners Properties

The tensile strength of a bolt is the maximum stress a material (254 SMO) can withstand when it is stretched before breaking. When a force produces a failure (sliding) on the alloy along the plane, parallel to the direction of the applied force; it is known as a shear load. Hence shear strength refers to the strength of 254 smo bolts against the loss of structural integrity when the alloy fails in shear.

Of the three fasteners, the construction of a hex bolt includes a hexagonal head and a threaded shank that effectively pins two materials together. This fastener is fastened to any material with the help of a nut. A stud, unlike a hex bolt, is threaded on both ends of its shank, without a head. Many times, studs will have an unthreaded section in the centre of their shank. UNS S31254 threaded rod is similar to a stud in construction. The only difference between the two is that the shank of the threaded rod is fully threaded.

An alternative to expensive nickel and titanium-containing alloys, the SMO 254 is a cheaper alternative that offers an effective solution. These fasteners have a higher impact toughness with a tensile strength that is two times more than stainless steel in the 300 series. It also exhibits resistance to chloride stress corrosion cracking. It has good resistance to both pitting and crevice corrosion.

The processing of hydrocarbons requires fasteners that can withstand both high temperatures and stress corrosion (hydrogen). As the alloy exhibits superior properties, it can perform well even in extreme conditions present in the petrochemical industry. Their high tensile strength makes SMO 254 bolts and nuts to be used in the chemical and food processing industries as well.
