Yazan Steel, located in Amman, Jordan, is a trusted manufacturer and supplier of high-performance alloy steel fastening solutions designed for demanding service conditions. They provide Alloy Steel Grade 2HM Fasteners, crafted to meet ASTM/ASME standards for high-temperature and high-pressure applications. These fasteners are engineered to offer outstanding strength, creep resistance, and long-lasting reliability even in harsh operating environments. Yazan Steel is committed to precise manufacturing, controlled heat treatment, and rigorous quality inspections to satisfy the stringent needs of the power, petrochemical, and process industries.
Alloy Steel Grade 2HM fasteners are made from a chromium-molybdenum alloy steel, typically featuring about 1.0–1.5% chromium and 0.45–0.65% molybdenum. This specific composition grants them high tensile and yield strength, enhanced creep resistance, and good oxidation resistance at elevated temperatures. Delivered in a quenched and tempered state, 2HM fasteners showcase excellent toughness, dimensional stability, and resistance to stress relaxation, ensuring dependable performance under sustained loads and thermal cycling.
