Applications
Applications: Piping systems: Flanges, valves, fittings Pressure vessels: Suitable for low to medium-pressure applications Mechanical components: Used in the fabrication of parts that do not require high strength or resistance to wear, such as brackets and structural supports.
Availability
Availability: A105 is commonly available in forgings, flanges, and pipe fittings. It is available in various shapes such as round bars, sheets, and plates.
Normalizing: 870-920℃ (improves toughness and refines the grain structure) Q+T (Quenching + Tempering): For higher strength (quenched at 880-900℃, tempered at 550-650℃ to improve mechanical properties and toughness) Annealing: Typically around 650-700℃ to soften the material and improve machinability Stress Relieving: Around 600-650℃ to reduce internal stresses and increase dimensional stability
