Alloy Steel Grade 10.9 Bolts are made from medium carbon alloy steel, enriched with elements like carbon, manganese, chromium, and molybdenum, which boost their strength and toughness. These bolts undergo a quenching and tempering process to achieve impressive tensile properties. They typically boast a minimum tensile strength of around 1000 MPa and a yield strength of about 900 MPa. This material offers excellent hardness, fatigue resistance, and solid wear performance, making Gr 10.9 bolts perfect for demanding mechanical and structural applications.
