Alpha Nickel

SMO 254 Fasteners Manufacturer, Supplier In Mumbai India

Alpha overseas is the name among very few in the manufacturing and exportation of SMO 254 Stainless Steel Fasteners. Super austenitic grade stainless steel is SMO 254. In this grade of stainless steel, molybdenum and nitrogen are the main alloying metals, along with the low carbon content. The alloy's high molybdenum and nitrogen content gives the fasteners excellent resistance to pitting and crevice corrosion. Furthermore, this grade of stainless steel is twice as impact-resistant as grade 316. It has high tensile strength.

These fasteners have a high degree of flexibility and impact resistance. These fasteners are utilised in environments with high chloride concentrations, such as salty water and seawater. The fastener assures excellent strength and superior toughness at cryogenic temperatures. Additionally, it has good mechanical characteristics in environments with both moderate and high temperatures.

Table Of Contents

The fasteners are forged at 982-1149℃, and post-process annealing is used to maximise their corrosion resistance. While cold working is accomplished using conventional techniques. Therefore, good hardenability is ensured by these cold processes. SMO 254 Fasteners are mostly used in power plants' flue gas desulfurization units. UNS S31254 SMO Fasteners, also known as SMO 254 Fasteners, offer incredible resistance to corrosive cracking under stress because of their cold production. The lack of moisture content or the hardening process's fast velocity makes machining challenges. The usage of this alloy does not require re-annealing at 120 degrees Celsius.

Since this alloy does not respond to heat treatment, the cold reduction is the preferred method for hardening it. Cold working is required to increase the toughness and strength of SMO 254 Fasteners but is typically difficult due to the rapid hardening rate. It is simple to produce and weld 254 SMO. It is made of sturdy, durable stainless steel.
