Yazan Steel is a trusted manufacturer and supplier located in Amman, Jordan, specializing in high-performance alloy steel fastening components designed for demanding service conditions. They offer Alloy Steel Grade B6 Washers, crafted to meet ASTM/ASME standards for high-temperature and high-pressure applications. These Grade B6 washers are specifically engineered to work seamlessly with B6 bolting, ensuring reliable load distribution, resistance to creep, and long-lasting structural integrity. Yazan Steel is committed to delivering precise dimensions, controlled metallurgy, and thorough quality checks to guarantee dependable performance in tough industrial settings.
Alloy Steel Grade B6 washers are made from a chromium-molybdenum alloy steel, typically featuring around 4–6% chromium and 0.45–0.65% molybdenum. This unique composition results in high tensile strength, excellent creep resistance, and outstanding performance at elevated temperatures. The washers also demonstrate good hardness, oxidation resistance, and structural stability under sustained loads. Delivered in a heat-treated state, B6 washers ensure mechanical integrity and compatibility with B6 studs and nuts, even in severe service conditions.

Alloy Steel Grade B6 washers find extensive use in high-temperature and high-pressure bolting assemblies. Common applications include power plants, boilers, pressure vessels, steam lines, petrochemical units, and refineries. They are frequently paired with B6 studs and nuts in flanged joints, valves, and critical piping systems. Thanks to their exceptional creep resistance and thermal stability, B6 washers are the go-to choice for services that involve elevated temperatures, cyclic loading, and long-term operation, where joint reliability and safety are paramount.
