At Esha Steel, a leading manufacturer and supplier in Kolkata, we provide high-quality Alloy Steel F12 Bars to industries across India. Manufactured to ASTM and ASME standards, these bars are engineered for moderate-to-high pressure and temperature applications, ensuring reliable and long-lasting performance. Esha Steel emphasizes precision, strict quality control, and superior mechanical properties. Widely used in power plants, petrochemical facilities, and industrial machinery, F12 bars deliver excellent toughness, corrosion resistance, and weldability, making them ideal for fabricating critical components, shafts, fasteners, and structural parts in demanding industrial environments where strength and safety are essential.
Alloy Steel F12 Bars are made from chromium-molybdenum low-alloy steel with carefully controlled carbon, manganese, phosphorus, sulfur, and silicon content. This composition provides high strength, toughness, and resistance to corrosion and creep under elevated temperatures. Mechanically, F12 bars offer tensile strength of 485–620 MPa, yield strength of 260–415 MPa, and good elongation with excellent impact resistance. Heat treatment enhances hardness, dimensional stability, and mechanical performance. Their uniform microstructure ensures excellent weldability, machinability, and durability, making F12 bars suitable for moderate-to-high pressure and temperature industrial applications.
