In the heart of Kinshasa’s dynamic industrial sector, Yoane Steel has established itself as a trusted partner for robust and reliable construction materials. We take pride in being your premier local manufacturer and supplier of Alloy Steel Grade 10.9 bolts, delivering the critical strength that Kinshasa’s growing infrastructure demands. Our commitment is to provide not just a product, but a foundation of trust and durability for the ambitious projects shaping our city’s future, ensuring every connection we supply is built to withstand the test of time and stress.
The exceptional strength of our Grade 10.9 bolts comes from a carefully balanced alloy composition, primarily based on carbon steel with precise additions of elements like boron and chromium. This specialized mix gives these bolts their remarkable mechanical properties, including a minimum tensile strength of 1000 MPa and a yield strength of 900 MPa. This means they are engineered to endure immense tension and shear forces without stretching or failing, offering a reliable margin of safety for critical applications where integrity is paramount.
