Detailed Information:

The RatnaExporter.com company is a reliable manufacturer, exporter, supplier, and retailer of high-quality products produced by using the best raw materials. In addition to bolts and screws, the supplier also offers threaded rods, washers, and other SMO 254 fasteners. The corrosion resistance is excellent and it is ideal for conventional SS, particularly halides containing acids. A variety of industries use these items, including the chemical industry, pharmaceutical industry, oil refinery, etc. They come in a variety of specifications and wall thicknesses depending on the buyer’s requirements.

SMO 254 fasteners are austenitic stainless steel fasteners that consider a high level of molybdenum, nitrogen, along with a low carbon content. They have excellent resistance to crevice corrosion, stress corrosion cracking, and pitting corrosion. These fasteners are also resistant to fatigue and uniform corrosion. They feature high ductility and impact strength compared to other steel alloys. They are also resistant to fatigue and uniform corrosion. These are fasteners used in high chlorides atmospheres such as seawater and in brackish water. They ensure superior toughness and high strength at cryogenic temperatures. They also exhibit good mechanical properties under moderate and high temperature conditions.

A post-process anneal is performed on forged fasteners at 982-1149 degrees C to ensure maximum corrosion resistance, while cold working is achieved by traditional methods, thereby ensuring good hardness.
