ASTM A193 B7 Fasteners are widely used across many high-pressure, high-temperature applications due to their excellent strength. These fasteners are manufactured from chromium-molybdenum steel, which gets heat-treated so that it gains increased strength and longevity. These fasteners are used across many sectors, including power generation, heavy engineering, petrochemicals, and the oil & gas industry, due to their excellent performance.
ASTM A193 B7 Fasteners are manufactured from alloy steel (AISI 4140 or 4142) and undergo processes of quenching and tempering to give them added tensile strength. ASTM A193 B7 Fasteners include bolts, studs, nuts, and washers, specifically designed to withstand very high temperature and pressure. ASTM A193 B7 Fasteners are used in flange connection, vessels, and pipeline assemblies.
Dalloyed, a well-known ASTM A193 Grade B7 Fasteners Supplier, ensures that all produced fasteners meet the highest quality. Each produced fastener is rigorously tested to ensure strength, longevity, and corrosion resistance.
