Based in the vibrant heart of Kinshasa, Yoane Steel stands as a trusted source for industrial-grade fastening solutions, catering directly to the robust demands of our nation’s growing infrastructure and manufacturing sectors. We take pride in supplying high-integrity components like the Alloy Steel Grade 10.9 Washer, engineered to meet the most challenging specifications. Our commitment is to deliver not just a product, but a promise of reliability and strength, ensuring that every project we support is built on a foundation of unwavering quality and local expertise.
The composition of the Alloy Steel Grade 10.9 Washer is carefully balanced to achieve its notable strength. Primarily a carbon steel enhanced with alloys like boron, it is heat-treated through quenching and tempering to reach its final properties. This process gives the washer its impressive mechanical characteristics, including a high tensile strength of 1040 MPa and a minimum hardness of 329 HV. This means it can handle substantial clamping forces without deforming, offering a dependable and robust performance in the most demanding situations.
