As a prominent SMO 254 Nuts Manufacturer in Dubai, UAE, we focus on crafting corrosion-resistant and high-strength fastening solutions designed for tough environments. Our dedication to precision engineering and adherence to international standards allows us to meet the varied needs of industries throughout the Middle East. Thanks to our strong logistics network, we ensure timely deliveries, making us a dependable partner for clients in Dubai who are in search of high-quality SMO 254 nuts for critical applications.
SMO 254 nuts are made from a high-alloy austenitic stainless steel that features increased levels of molybdenum, nitrogen, and chromium, which provide remarkable resistance to pitting and crevice corrosion. The typical chemical makeup includes 20% Cr, 18% Ni, 6% Mo, and 0.2% N. These nuts boast impressive mechanical properties, including a minimum tensile strength of 650 MPa and a yield strength of 300 MPa, along with an outstanding elongation of 35%. These traits make SMO 254 nuts perfect for harsh, chloride-rich environments such as marine, offshore, and chemical processing applications.
