Yazan Steel, based in Amman, Jordan, is a trusted manufacturer and supplier of high-performance alloy steel fasteners designed for demanding service environments. They provide Alloy Steel Grade B6 Bolts, crafted to meet ASTM/ASME standards for high-temperature and high-pressure applications. These bolts are engineered to offer exceptional strength, creep resistance, and long-lasting reliability, even in the toughest conditions. Yazan Steel guarantees precise threading, controlled heat treatment, and rigorous quality checks to satisfy the stringent needs of the power, petrochemical, and process industries.
Alloy Steel Grade B6 bolts are made from a chromium-molybdenum alloy, typically featuring around 4–6% chromium and 0.45–0.65% molybdenum. This combination results in impressive tensile and yield strength, outstanding creep resistance, and good oxidation resistance at high temperatures. Delivered in a heat-treated state, B6 bolts show dependable hardness, dimensional stability, and resistance to stress relaxation. Their mechanical properties guarantee safe and durable performance in continuous high-temperature and high-pressure environments.
