We are Naing Steel, a trusted manufacturer and supplier based in the heart of Naypyidaw, Myanmar, dedicated to supporting the nation’s growing infrastructure with unwavering quality. Our Carbon Steel F70 Forged Fittings are a testament to this commitment, engineered to meet the rigorous demands of high-pressure environments. We take pride in delivering components that are not only robust and reliable but also backed by our local expertise and a deep understanding of the specific needs of projects across Myanmar and the wider region.
The composition of Carbon Steel F70 is carefully balanced to deliver exceptional strength and durability. Primarily iron and carbon, its specific alloying elements are calibrated to achieve a minimum yield strength of 70 ksi, ensuring remarkable resistance to deformation under extreme stress. This controlled chemistry, combined with a precise forging process, results in fittings with superior mechanical properties, including excellent impact toughness and reliable performance, making them a cornerstone for secure and long-lasting piping systems.
