Naing Steel, based in the heart of Naypyidaw, is a trusted name for robust industrial solutions, proudly manufacturing and supplying high-integrity Alloy Steel Gr B7M Bolts. We understand that the strength of any major project depends on the quality of its smallest components. That’s why our focus is on delivering bolts that offer exceptional resistance to stress and corrosion, ensuring the safety and longevity of critical infrastructure and industrial systems across Myanmar, providing a foundation of reliability you can build upon with absolute confidence.
Crafted from a specialized alloy, these bolts derive their strength from a precise composition of chromium and molybdenum. This specific blend allows them to achieve impressive mechanical properties, including high tensile strength and excellent yield points, meaning they can withstand immense pressure without deforming. A key feature of the Gr B7M grade is its enhanced resistance to sulfide stress cracking, making it a safer choice for challenging environments where standard bolts might fail prematurely under corrosive duress.
