Alloy Steel Gr 8.8 Washers are generally made from carbon steel that’s alloyed with small amounts of chromium, molybdenum, and other elements to boost strength and durability. These washers go through heat treatment processes like quenching and tempering to achieve impressive tensile strength and hardness. They show excellent resistance to wear, fatigue, and moderate corrosion, making them ideal for heavy-duty applications. With a tensile strength of around 800 MPa and a yield strength of about 640 MPa, these washers ensure reliable performance in high-stress environments, providing secure bolted connections and a long service life even in demanding industrial conditions.
