Home > Stainless Steel 310/310S Nuts
Majid Fasteners stands out as a top manufacturer and supplier of Stainless Steel 310/310S Nuts in Dubai, UAE. They provide exceptional fastening solutions designed to perform reliably even in extreme temperatures and corrosive environments. The company has built a reputation for delivering precision-engineered products that meet international quality standards, ensuring they are durable and mechanically strong. Stainless Steel 310/310S Nuts are a popular choice for high-temperature applications thanks to their impressive oxidation and heat resistance. With state-of-the-art production facilities, rigorous inspection processes, competitive pricing, and prompt delivery, Majid Fasteners caters to a variety of sectors, including petrochemical, furnace manufacturing, power generation, marine, oil & gas, and thermal processing industries.
These nuts are made up of about 24–26% Chromium, 19–22% Nickel, up to 2% Manganese, 1.5% Silicon, and controlled carbon content—0.25% for 310 and 0.08% for 310S, along with trace elements like Phosphorus and Sulfur. The high levels of chromium and nickel provide outstanding high-temperature strength and oxidation resistance, capable of withstanding temperatures up to around 1100°C. They offer a tensile strength of approximately 520 MPa and a yield strength close to 205 MPa, along with excellent toughness and creep resistance. The lower carbon content in 310S improves weldability and reduces carbide precipitation during high-temperature fabrication.

Stainless Steel 310/310S Nuts find extensive use in high-temperature and highly corrosive industrial settings. They’re commonly found in furnace components, kiln structures, heat treatment equipment, boilers, combustion chambers, exhaust systems, and thermal processing units where resistance to scaling is crucial. These nuts are also essential in petrochemical refineries, power plants, steam pipelines, gas processing systems, and marine engineering due to their strength and durability in harsh environments. Additionally, they are utilized in food processing machinery and chemical production plants.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
