Nestled in the heart of Kinshasa, Yoane Steel stands as a trusted partner for industry, bringing robust materials directly to the fabric of our local economy. We take pride in supplying high-quality ARCELOR 400 sheet and plate, a material chosen for its remarkable resilience and strength. Understanding the demanding conditions of Congolese projects, we ensure this reliable steel is readily available to empower construction, manufacturing, and infrastructure development, providing a foundation built on both quality and dependable service right here at home.
ARCELOR 400 is a carbon steel known for its excellent balance of strength and workability. Its composition provides a minimum yield strength of 400 MPa, meaning it can withstand significant force without deforming permanently. This high strength is complemented by good toughness, allowing it to absorb energy, and it maintains these properties well even in challenging environments. Essentially, it offers a robust profile that can be cut, welded, and formed to meet the rigorous demands of heavy-duty applications, making it a go-to material for structural integrity.
