At Esha Steel, a leading manufacturer and supplier in Kolkata, we offer premium Alloy Steel Fasteners to industries across India. Manufactured to ASTM, ASME, and ISO standards, these fasteners are engineered for high-strength, durable, and reliable connections in industrial and structural applications. Esha Steel emphasizes precise dimensions, strict quality control, and superior mechanical performance. Widely used in petrochemical, power, automotive, construction, and heavy machinery sectors, alloy steel fasteners deliver excellent corrosion resistance, toughness, and wear resistance, making them ideal for securing critical components, machinery parts, pipelines, and structural assemblies in demanding industrial environments.
Alloy Steel Fasteners are made from chromium-molybdenum or other low- to medium-alloy steels with carefully controlled carbon, manganese, phosphorus, sulfur, and silicon content. This composition enhances tensile strength, toughness, hardness, and resistance to wear and corrosion. Mechanically, these fasteners provide tensile strength ranging from 600–1,200 MPa and yield strength from 400–900 MPa, depending on grade. Heat treatment improves hardness, dimensional stability, and fatigue resistance. Their uniform microstructure ensures excellent machinability and performance under high-stress and high-temperature conditions, making them suitable for critical industrial and structural applications.
