Committed to excellence, Chanchai Stainless blends cutting-edge technology with skilled craftsmanship to create stainless steel nuts that can endure harsh environments, making them a go-to choice for clients in need of top-notch fastening components in demanding sectors.
Stainless Steel 348 nuts are primarily made up of iron, chromium (around 20-23%), nickel (around 30-35%), and a touch of titanium, which helps stabilize the alloy and boosts its resistance to intergranular corrosion. These nuts boast impressive mechanical properties, including excellent high-temperature strength, maintaining toughness even up to 1100°F (593°C). They typically have a tensile strength of around 75,000 psi, along with high yield strength and remarkable fatigue resistance. Plus, Stainless Steel 348 offers outstanding oxidation resistance and stability during thermal cycling, making it perfect for critical fastening applications in high-temperature settings.
