254 SMO Products Manufacturer & Supplier in India
As a premier 254 SMO products supplier and stockist in India, we specialize in providing high-quality, high-performance super austenitic stainless steel. Our SMO 254 products list (UNS S31254) is a highly alloyed material with low carbon content, specifically designed for use in aggressive, chloride-rich environments like seawater.
Alloy 254 SMO's unique composition, which includes high levels of chromium, molybdenum, and nitrogen, gives it exceptional strength—almost double that of conventional 300 series stainless steels. This makes it a robust and reliable choice for demanding applications, offering superior resistance to pitting, crevice corrosion, and stress corrosion cracking. In addition to its strength and corrosion resistance, Alloy 254 SMO is prized for its high ductility and excellent impact toughness, even at low temperatures. It is often a cost-effective alternative to more expensive nickel and titanium alloys, without compromising on performance. The "6% Moly" designation for this family of alloys highlights its high molybdenum content, which is key to its outstanding corrosion-resistant properties.
The alloy's good weldability and formability allow for easy fabrication and enable its use in a variety of complex shapes. In its annealed state, Alloy 254 SMO also exhibits non-magnetic properties, a crucial characteristic for certain specialized applications.
Due to these features, Alloy 254 SMO is a preferred material in industries such as chemical processing, offshore oil and gas, power generation, and desalination plants.

Frequently Asked Questions About SMO 254
What is SMO 254 material?
SMO 254 is a high-alloy austenitic stainless steel. It is also known as a "6% Moly" steel due to its high molybdenum content, which gives it exceptional resistance to pitting and crevice corrosion.
Is 254 SMO magnetic?
In its annealed state, SMO 254 is non-magnetic. As a high-alloy austenitic stainless steel, it maintains a stable austenitic structure, which is not ferromagnetic. However, like many austenitic grades, some slight magnetism can be induced by cold working or severe deformation, though it generally remains non-magnetic for most practical applications.
What are the benefits of using SMO 254?
The main benefits are its outstanding resistance to stress corrosion cracking, pitting, and crevice corrosion, combined with high strength and good weldability. It offers a more cost-effective alternative to expensive nickel-based alloys in many applications.
How does SMO 254 compare to 316L stainless steel?
SMO 254 offers significantly better corrosion resistance than 316L, especially in chloride environ
