In the heart of Kinshasa, Yoane Steel stands as a trusted partner for industries requiring robust and reliable materials. We take pride in our role as a leading manufacturer and supplier, specializing in high-performance steel products that meet the most demanding specifications. Our focus is on providing exceptional ASME SA 387 Grade 12 Class 1 & 2 sheets and plates, materials engineered for resilience and critical service, ensuring your projects are built on a foundation of uncompromised quality and local expertise.
The composition of this specialized steel is a careful balance of chromium and molybdenum, giving it excellent strength and resistance to high temperatures. Mechanically, it is designed to perform under pressure, offering superior tensile and yield strength. The “Class 1” and “Class 2” designations refer to the heat treatment process; Class 2 undergoes additional tempering for enhanced toughness, making it suitable for even more severe operating conditions where durability is non-negotiable.
