As a trusted manufacturer and supplier based in Naypyidaw, Naing Steel is dedicated to supporting Myanmar’s vital industries with specialized materials built for challenging environments. We take pride in producing high-quality HIC Resistant Steel Sheet and Plate, specifically engineered to withstand the harsh conditions found in oil and gas and chemical processing. Our commitment lies in delivering robust, reliable solutions that ensure the longevity and safety of critical infrastructure projects across the nation.
Our HIC Resistant Steel is carefully formulated with a controlled chemistry, minimizing impurities like sulfur and phosphorus to prevent the formation of hydrogen-induced cracks. This results in a plate with excellent mechanical strength and toughness, capable of handling high-stress applications. The material’s uniform microstructure provides superior resistance to the damaging effects of wet hydrogen sulfide environments, ensuring structural integrity over the long term.
