Core Viewpoint - C276 alloy is a high-performance Cr-Mo alloy known for its strength, toughness, corrosion resistance, and good machinability, making it essential in aerospace, automotive, and electronic applications [2][3]. Material Characteristics - C276 alloy exhibits a tensile strength ranging from 500 to 600 MPa and a cold deformation limit of 300 to 400 mm/100mm, according to ASTM A 240-19 [2][4]. - The alloy demonstrates high corrosion resistance at room temperature, particularly in moderately corrosive environments, outperforming other Cr-Mo alloys [2]. Technical Parameters - C276 alloy complies with ASTM A 240-19 and GB 12741-2008 standards, which outline its performance indicators and chemical composition, including Cr content of 27.4-27.6% and Mo content of 1.5-1.7% [4]. Common Selection Misconceptions - Misconception 1: Overemphasizing high-temperature performance while neglecting its excellent strength and corrosion resistance at medium and room temperatures can lead to improper applications [4]. - Misconception 2: Ignoring the optimization of microstructure, which directly affects machinability, may result in processing difficulties if proper annealing or tempering is not conducted [4]. - Misconception 3: Focusing solely on cost while disregarding performance requirements can lead to economically unviable solutions, as C276's superior performance justifies its higher price in demanding applications [4]. Market Data - The market price for C276 alloy in 2023 fluctuates between $18,000 and $19,000 per ton, influenced by supply and demand dynamics, while C275 alloy is priced lower at approximately $17,500 to $18,500 per ton [3].
