At Esha Steel, a trusted manufacturer and supplier in Kolkata, we offer premium Alloy Steel F5 Bars to industries across India. Produced according to ASTM and ASME standards, these bars are engineered for moderate-to-high temperature and pressure applications, ensuring reliable performance and durability. Esha Steel emphasizes precision, strict quality control, and superior mechanical properties. Widely used in petrochemical, power, and industrial machinery sectors, F5 bars deliver excellent toughness, corrosion resistance, and weldability, making them ideal for fabricating shafts, fasteners, mechanical assemblies, and structural components where strength, safety, and long-term performance are critical.
Alloy Steel F5 Bars are made from low-alloy chromium-molybdenum steel with controlled carbon, manganese, phosphorus, sulfur, and silicon content. This composition provides excellent strength, toughness, and resistance to elevated temperature and pressure. Mechanically, F5 bars offer tensile strength of 485–620 MPa, yield strength of 260–415 MPa, and good elongation with reliable impact resistance. Heat treatment enhances hardness, dimensional stability, and high-temperature performance. The uniform microstructure ensures excellent weldability, machinability, and durability, making F5 bars suitable for moderate-to-high pressure and temperature industrial applications requiring long-term reliability and safety.
