Nakamura Stainless is a reputable manufacturer and supplier located in Pulau Ujong, Singapore, with a strong emphasis on high-quality stainless steel products. The company prides itself on its commitment to quality, precision, and customer satisfaction, offering a diverse array of stainless steel components tailored for various industries. One of their standout products, the Stainless Steel 304H Nuts, is celebrated for its remarkable corrosion resistance, strength, and durability, especially in high-temperature settings. Crafted to adhere to stringent industry standards, these nuts are perfect for critical applications where reliability is a must. Nakamura Stainless consistently provides top-notch solutions that guarantee performance, safety, and longevity for industrial and engineering requirements.
The Stainless Steel 304H Nuts are primarily made of iron, featuring 18–20% chromium and 8–10% nickel, which contribute to their excellent corrosion resistance and high-temperature strength. The ‘H’ designation signifies a higher carbon content (0.04–0.10%), enhancing their strength in elevated temperatures. They also include trace amounts of manganese, silicon, and phosphorus to boost their mechanical properties. These nuts boast a tensile strength of approximately 515 MPa and a yield strength of around 205 MPa, maintaining their structural integrity up to 870°C, making them ideal for high-stress environments. Plus, they offer good weldability and formability without sacrificing performance.
