Nestled in the dynamic industrial landscape of Kinshasa, Yoane Steel stands as a dedicated manufacturer and trusted supplier of essential materials for the region’s growth. We take pride in producing high-quality HIC Resistant Steel Sheet and Plate, engineered specifically to meet the stringent demands of challenging environments. Our commitment is to provide local industries with robust, reliable solutions that ensure safety and longevity in critical applications, supporting Congo’s development with strength and integrity from the ground up.
This specialized steel is carefully crafted with a controlled composition, typically featuring low levels of impurities like sulfur and phosphorus. The result is a material boasting excellent mechanical properties, including high tensile strength and impressive toughness. Its key feature, however, is its exceptional resistance to Hydrogen Induced Cracking (HIC), preventing internal damage that can occur in corrosive, wet environments, particularly those containing hydrogen sulfide.
