Alloy Steel Gr B5 Washers are crafted from chromium-molybdenum alloy steel, which provides outstanding hardenability, impressive tensile strength, and excellent wear resistance. The chromium content boosts hardness and corrosion resistance, while molybdenum enhances strength retention even at high temperatures. These washers maintain stable mechanical properties under thermal cycling, vibration, and heavy loads. After undergoing heat treatment, they exhibit improved hardness, fatigue resistance, and dimensional stability. Their well-balanced chemistry guarantees consistent performance in high-pressure and high-temperature situations, making them a reliable choice for demanding industrial applications.
