Tun Pipes, your trusted partner for industrial solutions in Nayyashin, is proud to offer Stainless Steel 304H seamless pipes, designed for demanding applications. We understand that the integrity of your project hinges on superior materials. Our 304H grade is specifically chosen for its excellent strength and corrosion resistance, ensuring long-lasting performance and reliability in high-temperature environments. When you source from us, you’re not just buying pipes; you’re investing in quality and a partnership dedicated to supporting Myanmar’s growth. Let us be the foundation for your next big achievement.
Crafted from a precise composition of 18-20% chromium and 8-11% nickel, with a key addition of carbon held between 0.04-0.10%, the 304H grade is engineered for strength. This specific chemistry grants it enhanced tensile strength and superior yield strength, especially important when things heat up. Essentially, these pipes are made to maintain their structural integrity and resist deformation under high pressures and temperatures, making them reliably robust for challenging industrial duties that standard 304 grades can’t handle.
