With a dedication to excellence, MERIH STAINLESS makes sure that every product goes through thorough quality checks, establishing itself as a reliable choice for industries that need dependable fastening solutions. Their deep knowledge in metallurgy and production technology allows them to deliver nuts that excel in performance, longevity, and resistance to tough environments.
Stainless Steel 309S Nuts are primarily made of iron, chromium (about 23–25%), and nickel (around 12–14%), which gives them outstanding resistance to oxidation and corrosion. These nuts boast high tensile strength, excellent toughness, and superior thermal stability, making them perfect for high-temperature applications. Their mechanical properties include good ductility, hardness, and resistance to scaling, ensuring they perform reliably even in demanding situations. The low carbon content of the alloy enhances weldability while keeping strength intact, making them durable for both structural and high-temperature industrial uses, meeting strict engineering standards in mechanical and chemical settings.
