Lecong Stainless, located in Da Nang, Vietnam, has built a solid reputation as a reliable manufacturer and supplier of top-notch stainless steel products, including Stainless Steel 304H Nuts for clients in Dubai, UAE. Known for their precision engineering and commitment to international standards, this company guarantees consistent product reliability and durability. Thanks to their cutting-edge manufacturing techniques and rigorous quality control, they’ve become the go-to choice for industries that need strong fasteners. With a keen focus on both local and global markets, Lecong Stainless blends technical know-how with customer-focused solutions, providing stainless steel nuts that meet the high standards of today’s engineering and construction projects.
Stainless Steel 304H Nuts are mainly made up of iron, chromium (18–20%), and nickel (8–10.5%), along with small amounts of carbon, manganese, and silicon. The “H” grade signifies a higher carbon content, which enhances strength at elevated temperatures. These nuts boast impressive mechanical properties, featuring a tensile strength of about 515 MPa, a yield strength of around 205 MPa, and an elongation of 40% or more. They are exceptionally resistant to corrosion, oxidation, and scaling, making them perfect for tough environments. Their hardness, toughness, and ability to maintain structural integrity under thermal stress make them ideal for critical engineering applications.
