Nestled in the heart of Manama, Bahrain, Niazi Stainless stands as a trusted manufacturer and supplier for all things stainless steel. We take pride in producing high-grade components, including our robust Stainless Steel 304H Nuts, crafted to meet the most demanding industrial standards and ensure lasting performance in critical applications.
These nuts are forged from a specific composition, primarily 18-20% chromium and 8-11% nickel, with a touch more carbon than standard 304. This enhances their strength, particularly at high temperatures. They offer excellent mechanical properties, including impressive tensile strength and good resistance to corrosion, making them reliably durable under stress.
