Yousef Steel is a well-respected manufacturer and supplier based in Riyadh, Saudi Arabia, specializing in high-quality Alloy Steel Gr B6 Washers for various industrial and engineering needs. These washers are crafted to meet ASTM A193 standards, ensuring they perform exceptionally well in high-temperature and corrosive settings. Renowned for their precision, durability, and strength, Alloy Steel Gr B6 Washers provide secure fastening, even in the toughest operating conditions. Yousef Steel is committed to strict quality control and compliance with international standards, making these washers a dependable choice for industries such as oil & gas, petrochemicals, power generation, marine, and construction.
Alloy Steel Gr B6 washers are made of chromium-molybdenum alloy steel, typically with a composition of around 0.30–0.40% carbon, 0.75–1.20% manganese, 0.50–0.80% chromium, and 0.15–0.25% molybdenum. The washers possess better mechanical properties like high tensile strength (minimum 105 ksi), yield strength (minimum 85 ksi), and hardness (HRC 23-35). They have superior resistance to wear, toughness, and corrosion, hence used for high-stress applications like petrochemical, construction, and automotive industries. Heat-treated for added strength, B6 washers resist distortion in severe conditions and provide consistent performance in harsh environments.
